Cayenne's PCV Valve Service at Allied Auto Works in Los Altos

cayGood day, it's Cayenne again and today we will bark all about PCV Valves and the service they need.  So let's get barkin!

 

 

 

Today, we are talking about your PCV valve. Unburnt fuel is forced into the crankcase as your engine runs.  The PCV (positive crankcase ventilation) valve vents this unburnt fuel and oil vapors from the crankcase and sends it back into the air intake system to be burned in the engine.  A clogged PCV will not allow these vapors to escape. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause vehicle engine corrosion, something we see occasionally at Allied Auto Works. At high speeds on CA freeways, the pressure can build up to the point that gaskets and seals start to leak.

Back in the old days, vehicles were simply installed with a hose that vented these gases out into the atmosphere. But starting in the 1964 model year, environmental protection laws required that these gases be recycled back into the air intake system to be mixed with fuel and burned in the vehicle's engine.

This is much better for air quality and improves fuel economy also. (Budget-conscious Los Altos drivers take note!) The little valve that performs this important function is the PCV valve. The PCV valve lets  gases out of the engine, but won't let anything back in. Over time, the vented gases will gum up the PCV valve and it won't work well. That can lead to all of the problems I've already described, oil leaks, excessive oil consumption and decreased fuel economy.

Fortunately, it's very easy to test the PCV Valve at Allied Auto Works in Los Altos and quick and inexpensive to replace. Even so, it's often overlooked because many Los Altos vehicle owners don't know about it. Check your vehicle owner's manual or ask your Allied Auto Works service advisor. If this is the first time you've heard of a PCV valve, you might be in line for a replacement.

There's another aspect to the PCV system. In order for the valve to work correctly, it needs a little clean air to come in. This is done through a breather tube that gets some filtered air from the engine air filter. Now some vehicles have a small separate air filter for the breather tube called the breather element. That'll need to be replaced at Allied Auto Works when it gets dirty.

Please ask your Los Altos service advisor Matt or Travis about your PCV valve. For the price of a couple of burger combo meals in Los Altos, you can avoid some very  expensive engine repairs.  Til next week with Duke, this is Cayenne        cay

Duke Is Watching Your Check Engine Light

dukeWell hello, it's Duke and I am keeping a watch on your Check Engine Light.  Are you???  Let's get barkin about what to watch out for!

 

 

Did you know that most of the cars driving around Los Altos, CA carry more computer power than the Apollo 121 Lunar Module that landed on the moon in 1969?

New cars sold in the Los Altos area have as many as twelve networked computers and over five miles (eight kilometers) of wiring. In fact, for the last decade or so, auto computers have been controlling about 85 percent of your vehicle's functions.

Cars have sensors for manifold air temperature, coolant temperature, manifold air pressure, airflow, throttle position, vehicle speed and oxygen content. All of this electronic wizardry is pretty complicated. So how do Los Altos drivers know when there is a problem?

It's simple; the Check Engine light comes on. The computer monitors all the sensors and uses that information to decide what to adjust such as the fuel mix, spark timing and idle speed. In addition, the computer monitors its own circuits. When it finds a fault, it turns on the Check Engine light and stores a trouble code in the computer.

It can be pretty disturbing for Los Altos drivers when the Check Engine light comes on. We wonder just how urgent it is. Generally speaking, it is not critical like a temperature or oil pressure light. When you get one of those it means STOP NOW! When the Check Engine light shows up, you should come in to Allied Auto Works in Los Altos to find out what the matter is as soon as possible.

Since 1996, there has been a strong emissions control component to the Check Engine diagnostic. But if your Check Engine light flashes on and off, you know that it is more urgent and you need to get it checked immediately to prevent damage. You should slow down and avoid towing or heavy loads until you can get it checked out.

Your friendly and knowledgeable technicians at Allied Auto Works have special diagnostic equipment that will retrieve the trouble code from the computer and help him determine what is wrong. From there, we can fix it and get you back on the road.

  Stop by if you're check engine light is on and tell them Duke was keeping a watchful eye for you.     duke

Cayenne's Fuel Saving Tip for Los Altos: Check Engine Light

cayCayenne here today and here's a question for all my Los Altos neighbors :

 How long have you been enjoying the romantic glow of your check engine light?   Well that is what we will focus on today, let's get barkin'!


Hey, it's not there to create ambiance; it's a warning that something's wrong. (And, by the way, Homer Simpson's fix of covering it with tape is not a good idea.)

Many conditions that trigger the check engine light can hurt your vehicle. A lot.

If your date's eyes are smoldering in the soft glow of the check engine light, try to think of all the gas money you'll save by getting it fixed. Give Allied Auto Works a call when you areready and tell them Cayenne sent you! cay

Duke Asks "Are Modern Vehicles Maintenance Free?"

dukeIt's Duke and do you believe that today's sophisticated and modern vehicles are maintenance free?  Well today we will bark about this and find out the truth......let's get barkin'!

 

 

 

In our auto video today we'll be talking with Alan Peterson about myths surrounding automotive maintenance. You can lump these myths into the statement that "modern cars are so reliable, they are virtually maintenance free".

Any good myth has some elements of truth. No offense to Los Altos Bigfoot fans, but this maintenance-free myth has more evidence than most. If we look at some isolated areas of auto maintenance, we could conclude that maintenance isn't so important. But other areas would just as easily lead you to believe that maintenance is more important than ever.

Here are some examples for our friends in Los Altos.

  • Some cars in Los Altos no longer require chassis lubrication. They're made with self-lubricating materials and have sealed joints. There's literally no way to grease those joints.

-Chalk one up for the myth.

On the other side, some vehicles come with sophisticated variable valve timing. A lot of complicated parts up in the valve train that didn't even exist not that many years ago. These parts are very vulnerable to oil sludge.

  • So, skipping an oil change here and there could lead to very expensive damage.

-A point to maintenance.

  • Electronic ignition has eliminated replacing points.

-Myth gets a point.

  • Fuel injectors on direct injection engines are very expensive to replace so one must be sure to get a fuel system cleaning on schedule.

-Point for maintenance.

I think you get the picture. As automotive technology advances, it eliminates or reduces some maintenance requirements. And maintenance becomes more critical for some items. Most others remain very similar to what they've always been.

So the maintenance mindset is still important for car owners in Los Altos if we want our vehicles to last a long time. The checklist may change over time, but there'll always be a check list.

Your friendly and professional service advisors, Matt & Travis at Allied Auto Works can answer any questions you have about your vehicles maintenance schedule.

Til next week, this is your friendly Automotive Dog Blogger, Duke!   duke

Cayenne Answers "Why Wheel Balancing and Tire Rotation Save You Money on Tires"

cayCayenne here and today we will do a balancing act.  Wheel balancing and tire rotation that is!  So let's get barkin!

 

 




Los Altos drivers want their tires to last as long as possible. Two ways to extend tire life are wheel balancing and tire rotation.

When wheels are out of balance, they wobble and vibrate. That makes the tires wear in a cupping pattern. If a front wheel is out of balance you'll feel it in the steering wheel. If it's a rear wheel you'll feel it through your seat. To fix this, your technician at Allied Auto Works puts weights on your wheels to balance them out.

That brings us to tire rotation. The front tires on a vehicle wear out faster than the rear tires. As they push through turns, the shoulders of the front tires wear down. So rotating front and rear tires allows them to all wear at about the same rate over the life of the tire.

Proper tire inflation will also help Los Altos folks' tires last longer. Under-inflated tires wear more on the shoulder and may even overheat. This could cause tire damage or a blow out. Over-inflated tires wear too fast in the middle.

Four wheel drive trucks and SUV's tend to wear their tires more unevenly so rotation is even more with them. Give Allied Auto Works a call to get our recommendation for your vehicle.

See your owner's manual or ask your service advisor at Allied Auto Works for your recommended tire rotation schedule. It's usually every 5,000 to 8,000 miles.

Tires are one of the most important safety components on your vehicle. Take care of them and they'll take care of you. 

This is Cayenne and til next week check in with Duke !    cay
