Duke's Diagnostic Service Tips At Allied Auto Works

duke

Hey, it's Duke and imagine waking up one morning with a stomach ache from too many steak bones. You pick up the phone, call the doctor's office and say, “I’ve got a really bad tummy ache. How much will it cost to make me feel better?” Of course, you wouldn’t do that. You know that there could be a lot of reasons for your symptoms and that the doctor will have to examine you, ask some questions and probably run some tests before she can tell you what’s wrong and give you treatment options. 

This same scenario plays out every day at CA auto repair facilities. When the cause of the concern isn’t obvious, the car will need to undergo a diagnostic examination. The typical car has about 30,000 parts, including several networked computers and miles of wiring. Finding exactly what is wrong can be very complicated and take some time. The most experienced technicians at Allied Auto Works in Los Altos are the ones who tackle the difficult diagnostic jobs. Once they have determined the cause of the trouble, they can work out the plan for how to fix it and tell you how much it will cost.

When you think about it this way, it makes perfect sense that, 1) the Allied Auto Works service advisor cannot provide an estimate before the diagnosis is done, and 2) there is a charge for auto diagnostic services in Los Altos. You expect to pay for an office visit to the doctor and for any necessary tests before you can be presented with your treatment options and costs; same goes for your vehicle.

We know it can be frustrating for Los Altos drivers when something is wrong with your car and you aren’t sure what is going to be involved in getting it fixed. We are passionate about helping you through the process, communicating with you at each step along the way. We have highly trained diagnostic technicians and technologically-advanced diagnostic equipment to uncover the cause of your trouble. We use quality replacement parts to help make sure you stay on the road after the repair is done. That’s our prescription for automotive peace of mind.


Give us a call and tell them Dr. Duke sent you and I leave you with my doctor joke of the day,

Patient: “Please help me! I can’t stop my hands from shaking.”

Doctor: “Do you drink often?”

Patient: “Not really, I end up spilling most of it.”

Cayenne Says "So You Think You Sound Like a Hot Rod (Noisy Exhaust System)"

CAY 

Cayenne here and my first dog ride was in a 67 SS 350 Camaro, now that was a hot rod.  What a beautiful sound when it drove down the road.  But have you heard some cars so loud even I want put in the dog earplugs.  What is that horrible sound and believe me it ain't not hot rod.  Welcome to the noisy exhaust system so let's roar into this subject today!

Driving along, your exhaust system's rumbling so loud that people turn and stare at you pass by.  You're wondering when the police are going to pull you over for illegal noise.

Your mind immediately thinks, aha! A broken muffler. 

Well, your exhaust system is composed of many more parts than just a muffler. 

Your engine makes power because of thousands of tiny explosions from detonating fuel.  Those explosions make a racket, so engineers came up with a system that acoustically dampens that sound in addition to getting rid of harmful exhaust.

In the engine is the exhaust manifold that looks like several pipes that join up into one pipe.  It directs exhaust to the catalytic converter. The catalytic converter converts harmful gases into less harmful gases using certain chemical reactions.  Then comes the muffler that has baffles inside to quiet the sounds of your engine noise.  Finally: the tailpipe.

All of those pipes and parts are joined together by clamps and held up by brackets, and they ride over some pretty bumpy roads.  They are also exposed to elements, like salt, water, rocks, and grit.  Chances are that one of those clamps or brackets has been weakened by corrosion.  When you hit a bump, bingo! The crack widens into a gap and there's a spot for the engine noise to come roaring out instead of being directed into the muffler's quieting chambers.

You might be surprised to know that the exhaust system can rust from inside out.  How? Moisture is one component of exhaust, and moisture on the inside can do the same kind of damage as moisture from the outside. 

It's a good idea to have your exhaust system looked at regularly by a technician.  He or she can evaluate the condition of the metal and recommend when it might be time to replace parts before they break.

Then you'll have a decision to make.  Newer exhaust systems are made out of stainless steel that is much less prone to corrosion issues.  Others are made of aluminized steel that also fights rust.  You've probably already guessed that they can cost more, but the extra price upfront may give you an exhaust system that will last much longer. 

Sure, with a repaired exhaust system, you won't have quite the head-turning vehicle you once had.  You'll just have to live with all the quiet.

It's got a Lincoln motor
And it's really souped up.
And that model A body makes it look like a pup
It's got eight cylinders; uses them all.
It's got overdrive, just won't stall.  ~Lyrics from Hot Rod Lincoln

Duke's Positive Crankcase Ventilation - PCV Valve Service at Allied Auto Works

duke

Hello Los Altos!    Duke here and did you know that the first federally-mandated emissions control device was introduced in the 1960's? The Positive Crankcase Ventilation valve, or PCV valve, has been installed in CA vehicles since 1964 and represents the first legislation by the United States government to regulate harmful emissions as well as to improve performance in the country's vehicles.  So today we will bark PCV and what it means for you and your vehicle.  So let's get barkin'!



The PCV valve, as you can probably guess, is located on the crankcase. The crankcase is the lowest part of a vehicle's engine. It houses the crankshaft and the engine oil. The crankshaft connects to the pistons that power the engine.

Pistons are pushed down when fuel is burned in an engine. This causes the crankshaft to rotate, which sends power to the transmission.  It ultimately turns the axles and causes the vehicle to move. Some of the gases released by the burning fuel squeeze around the pistons and down into the crankcase.

If the escaped gases mix with the engine oil in the crankcase, oil sludge develops. This sludge has the consistency of petroleum jelly and can cause damage by clogging up passageways in the engine. Further, escaped gases can build up pressure inside the crankcase that can blow out seals and gaskets.

Before 1964, a hose was attached to the crankcase that vented escaped gases out into the air. These gases contained about 70% unburned fuel as well as harmful emissions. The PCV valve was designed to curb these harmful emissions as well as recapture unburned fuel.

The PCV valve is a small, one-way valve that allows escaped gases to exit the crankcase. The gases are then routed into the intake system so they can be re-burned in the engine. Fresh air enters the crankcase through a breather tube to facilitate this circulation and keep the air in the crankcase clean.

The PCV valve, like most working parts on a vehicle, will wear out over time. Usually it simply gets gummed up. Preventive maintenance, including routine oil changes at Allied Auto Works in Los Altos, will extend the life of the valve, but eventually it will have to be replaced. A sticking PCV valve won't allow gases to circulate properly, which can increase pressure in the crankcase. Over time, that pressure will lead to oil leaks.

Your vehicle manufacturer recommends that a PCV valve be replaced every 20,000 to 50,000 miles (32,000 to 80,000 kilometers), depending on the vehicle and Los Altos driving conditions. It's an inexpensive repair but may not be included in the maintenance schedule in your owner's manual.  So if you're looking for auto advice about the PCV valve, you may have to ask our pros at Allied Auto Works.

duke

Taking care of our PCV valve protects the environment in CA and improves vehicle performance. It's just part of good vehicle care for Los Altos drivers and a way all of us can do our part to improve the world we live in.

Cayenne's Question Of The Week: "PCV Valve, What Is It?"

cayPCV, hmmm...... what does that stand for?   Pork, Chicken and Venison?  No unfortunately it does not.   Hi Cayenne here and today we will answer that question.  What does PCV stand for and what is a PCV Valve?   So let's get barkin!

Most  drivers in Los Altos, Cupertino and Mt. View  know something about preventive maintenance on a vehicle. We know we should routinely replace the oil and wiper blades and other fluids. But have you heard of a PCV valve ? This little car part needs to be replaced regularly or it can cause some serious problems in your vehicle engine.

PCV stands for Positive Crankcase Ventilation. The crankcase holds your motor oil and is located at the bottom of your engine.

When fuel is burned in your engine, it produces waste gases that are mostly vented out through your exhaust system. But some of these gases push their way past the pistons and into the crankcase. There, these gases can mix with motor oil to produce oil sludge, which can damage vehicle engine parts through corrosion and by clogging engine passages. Los Altos vehicle owners should be advised that if the engine is running at high speeds, these gases can also cause pressure inside the crankcase to build up. This pressure, in turn, can blow gaskets and damage seals, leading to oil leaks.

The waste gases that leave the engine are comprised of about 70% unburned fuel. They used to be vented off the crankcase into the atmosphere. But starting in 1964, laws mandated that these gases be recaptured. Manufacturers began installing PCV systems, which recycled the gases into the air intake system where they could be mixed with fuel and sent to the engine to be burned.

The PCV valve is a one-way valve attached to the crankcase. Waste gases exit the crankcase through the valve but cannot enter.

Over time, the waste gases leave deposits on the PCV valve that can gum it up. So it needs to be replaced occasionally. This is an inexpensive part of preventive maintenance that is often overlooked, but which can have very expensive consequences. It's good auto advice to keep this little valve clean and working well.

In order to maintain efficient circulation, the PCV system also has a breather tube that allows clean air to enter the crankcase. This air is usually filtered through the engine air filter. But some vehicles have a separate air filter for the breather tube called the breather element. If this is the case with your vehicle, proper maintenance of the PCV will include replacing this element. To find out whether your vehicle has this type of PCV system, check your owner's manual or ask your service advisor at Allied Auto Works.

The PCV system reduces harmful vehicle emissions. The maintenance it requires is simple and inexpensive at Allied Auto Works. A fouled or damaged PCV system can lead to serious engine damage for Los Altos drivers.


Let's all learn to practice good car care. It's good for our wallets, and it's good for our CA environment.   Now  I think I will go cook me up some Pork, Chicken and Venison.

Cayenne's Exhaust Service at Allied Auto Works: Passing the Smell Test

cay nose

Hi Cayenne here today and being a Hound Dog, I have a nose for smells!  Today I will bark about your exhaust and passing the Smell test.  So let's start sniffin that exhaust!

 

The exhaust system on a vehicle is more complex than most Los Altos residents realize. It contains everything from old-fashioned pipes and clamps to sophisticated computers and sensors. All CA folks know a properly functioning exhaust system is good for the environment, but sometimes we forget that a damaged exhaust system can be deadly. That's why preventive maintenance on your exhaust system is so . We can help you with that at Allied Auto Works in Los Altos.

The exhaust manifold is the first component in your exhaust system. The manifold is attached to the engine. It collects the gases that are produced by the engine and directs them into the exhaust pipes. At this point, these gases are both hot and chemically dangerous.

One of the gases produced in your engine is carbon monoxide. This gas is colorless and odorless. Breathing it can cause headaches, dizziness, nausea and drowsiness. Continue breathing it, and you will die.

To keep this gas, and others, from entering your vehicle passenger compartment, the connections from the manifold to the engine and from the manifold to the exhaust pipes are sealed with gaskets. These connections should be routinely inspected at Allied Auto Works for cracks and to check if they have come loose.

The exhaust pipes can also get damaged, allowing dangerous gases to leak into your passenger compartment. These pipes can rust or be dented or broken by rocks and other roadway debris, so they need to be inspected regularly.

The catalytic converter is the next component in your vehicle exhaust system. You can breathe a sigh of relief now, because this is where the dangerous engine gases are converted into carbon dioxide and water, greatly reducing the amount of harmful emissions in your exhaust. You'll also be happy to know that your catalytic converter doesn't require maintenance. However, it will wear out. If you fail an emissions inspection because of a faulty catalytic converter, you need to replace it.

The muffler's job is far less critical, but far more noticeable, than the catalytic converter's. It dampens or absorbs the noise from the engine. Most Los Altos residents don't realize that we can actually customize the noise our car makes with a custom muffler. You can upgrade to a muffler that will make your car sleuth-quiet, or you can advertise your presence in Los Altos with a sassy rumble.

Mufflers can also rust or be damaged by road debris. But just because their main function is to dampen out engine noise doesn't mean they can be ignored. If your muffler is leaking, you need to get it replaced quickly. Exhaust fumes need to exit through your tailpipe, not your muffler.

The exhaust pipe contains at least one oxygen sensor. The sensor monitors the oxygen content of the exhaust, which allows it to adjust the fuel-to-air ratio in the engine. This keeps your vehicle engine running smoothly and maintains good gas mileage. So, besides keeping you and the environment healthy, a well-maintained exhaust system also keeps your vehicle healthy. The tailpipe itself can rust or get damaged by road debris, so it needs a quick inspection once in a while, too.

The whole exhaust system is mounted on the vehicle with clamps and hangers. These clamps and hangers can come loose, rust or get dinged up by road debris. Remember that the gases in your exhaust system are hot, so the exhaust system itself gets hot. The clamps and hangers keep the exhaust system attached to the vehicle, but they also prevent the heated components from touching things they shouldn't. If you don't inspect and replace broken, loose or damaged clamps, you may end up with melted wires, hoses or lines. And that can spell some expensive repairs.

You should schedule an exhaust system inspection as recommended in your vehicle owner's manual. Because this system is critical to your health and the health of your car, and because of its sophistication and complexity, you need to have the work done at a qualified service center such as Allied Auto Works in Los Altos.

Maintaining your emissions and exhaust system is not just good auto advice: it's good health advice for all Los Altos residents and their families.

Exhaust Service



Whenever we talk about exhaust service, most people normally think about exhaust pipes and mufflers. Well, actually, exhaust service is a lot more comprehensive these days. For example, catalytic converters were mandated in 1976 and on-board emission control computers in 1990. Governmental emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental regulations.

Exhaust service has really become exhaust and emissions service. High-tech computer controlled emissions devices are now a big part of exhaust service. Because it is so sophisticated, your vehicle manufacturer recommends you have your emission system checked out by a qualified Los Altos exhaust technician regularly to make sure everything is working right - usually every 6 months or 10,000 miles/16,000 kilometers.

If your Check Engine light comes on, especially if it's flashing, get your car looked at right away. Technicians at Allied Auto Works handle emission problems everyday. You might have exhaust or emissions trouble if your car is difficult to start, runs rough, is noisy or smoking. Call Allied Auto Works at 650.968.7227 to schedule an appointment if you experience these problems.

Let's review the exhaust system. We will start from the top and start with the exhaust manifold. That is the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe. Exhaust gaskets help seal the connection with the manifold and various other joints along the way. If the manifold is cracked or loose, or a gasket is leaking, dangerous gases could escape into the passenger compartment, where you ride. Carbon monoxide can be deadly, so it is important that your exhaust system doesn't leak. The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next is the catalytic converter. This part looks like a muffler. It changes chemicals that are dangerous to your health and the environment into harmless carbon dioxide and water. It doesn't require any maintenance itself. But eventually they wear out. You will find this out when your car fails an emissions inspection.

Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car's sound with different mufflers - anything from whisper quiet to bad-boy rumbley. Rusted or road-damaged mufflers can leak and need to be replaced right away.

The exhaust system is attached to the car by a series of hangers and clamps. These fasteners hold the system in place. When hangers come loose or break, hot exhaust components can touch and melt wires, hoses and lines.

Finally, we end at the tailpipe. This is the final outlet for the exhaust. These can be plain-Jane or pretty flashy. Also, the oxygen sensors monitor the oxygen content of the exhaust so the engine control computer can adjust the fuel-to-air mix to keep the car running right.

Exhaust and emissions service covers plain old pipes and high-tech computers. It impacts everything from life and death safety due to exhaust leaks, to fine-tuning the sound of your ride.

Cayenne & Allied Auto Works Service For Your Exhaust System

cay

Hi Cayenne here and I am just exhausted thinking about the exhaust system but it is important. So here goes!

Your sedan’s exhaust system is more than just a tailpipe and a muffler. In fact, it is one of the most complex systems on your sedan. Maintaining it is good Allied Auto Works auto advice for Los Altos drivers, but it’s also good health advice and good environmental advice.

The exhaust system includes your emissions system. Because this system may affect your health and the health of our Los Altos area environment, it is subject to strict government regulations. Satisfying these regulations demands some high-tech, computer-controlled equipment, which means that the emissions system is a lot more sophisticated than it was thirty years ago. Most vehicle manufacturers recommend that you have your sedan exhaust and emissions systems checked by a qualified technician at regular intervals.

The exhaust system starts with the exhaust manifold. Allied Auto Works Service For Your Exhaust SystemThe manifold is attached to the sedan engine. It collects exhaust from the cylinders and directs it into the exhaust pipe. Gaskets seal the connection of the manifold to the engine and to other joints. A cracked or loose manifold or a leaking or damaged gasket can allow dangerous gases to enter the passenger compartment of a vehicle. One of these gases is carbon monoxide, which is colorless, odorless and deadly. For this reason, it is critical that Los Altos drivers keep their exhaust system in good repair.

The pipes that connect the various parts of the exhaust system can rust or be damaged by rocks or other road debris. Such damage can cause dangerous gases to leak into the air. So it is essential that exhaust pipes get a diagnostic examination regularly.

The catalytic converter is the next vital component of your sedan exhaust system. It sort of looks like a muffler. Its job is to change dangerous gases into harmless carbon dioxide and water. The catalytic converter doesn’t require any regular maintenance, but it can wear out. If it fails, you will need a new catalytic converter to pass an emissions test in CA. Call Allied Auto Works at 650.968.7227 if you suspect a problem with your catalytic converter.

Oxygen sensors in the exhaust pipe monitor the oxygen content of the exhaust. This helps the sedan engine’s computer keep the fuel-to-air mixture at optimal levels.

The muffler is also part of your sedan exhaust system, but it deals with a different kind of emission. It keeps your sedan from emitting bad sounds. Mufflers act like finely tuned musical instruments. They create a feedback of sound waves to absorb or decrease the noises made by your engine. Different mufflers can create different sound waves, so you can actually “tune” your car to produce a particular sound, anything from whisper to rumble.

It is critical for damaged mufflers be replaced immediately at your Los Altos automotive service center, especially if they are leaking. Not only will the extra noise annoy your Los Altos neighbors, a leaky muffler could be serious.

The entire exhaust system is attached to your sedan by hangers and clamps. These fasteners can rust, come loose or break. The critical components of the exhaust system can get very hot, so when the hangers or clamps fail, these hot components can come into contact with other parts such as wires and hoses. These can melt, causing serious and expensive damage to your vehicle. Good car care requires that you have your exhaust system inspected regularly.

Let’s not forget the tailpipe. It’s the last vital piece in the exhaust system — and of your sedan, for that matter. Exhaust fumes exit your sedan through the tailpipe.

If your sedan has any of the following symptoms, it may have a problem with the exhaust system: it’s hard to start, it runs rough, it’s noisy, it’s smoking. Also, if your “check engine” light comes on, especially if it’s flashing, it is important to get your sedan to Allied Auto Works in Los Altos right away. Often, the “check engine” light indicates a problem with the emissions system.

Caring for your sedan exhaust system yields cosmetic benefits like quieting your engine sounds, but also may impact your health and safety. Your life, or the life of a loved one, may actually be on the line.

Well go out and get the exhaust system checked today!
