PCV Valve Service At Triangle Auto Service In Chicago

Today, we are talking about your PCV valve. The PCV Valve is a little, inexpensive part that does a vital job for Chicago drivers. PCV stands for Positive Crankcase Ventilation.

The crankcase is the bottom area of the engine that holds the oil. When the Minivan engineís running, fuel is burned to generate power. Most of the exhaust from combustion goes out through the exhaust system. But some exhaust blows by the pistons and goes into the lower engine, or crankcase.

These hot gases are about seventy percent unburned fuel. This can dilute and contaminate the oil, leading to damaging engine oil sludge. It can also cause Minivan engine corrosion, something we see occasionally at Triangle Auto Service. At high speeds on Chicago freeways, the pressure can build up to the point that gaskets and seals start to leak.

Back in the old days, manufacturers simply installed 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 Minivan's engine.

This is much better for air quality and improves fuel efficiency also. (Budget-conscious Chicago drivers take note!) The little valve that performs this important function is the PCV valve. The PCV valve lets harmful gases out of the engine, but wonít let anything back in. Over time, the vented gases will gum up the PCV valve and it wonít work well. That can lead to all of the problems Iíve already described, oil leaks, excessive oil consumption and decreased MPG.

Fortunately, itís very easy to test the PCV Valve at Triangle Auto Service in Chicago and quick and inexpensive to replace. Even so, itís often overlooked because many Chicago auto owners donít know about it. Check your Minivan ownerís manual or ask your Triangle Auto Service service adviser. If this is the first time youíve heard of a PCV valve, you might be in line for a replacement.

Thereís 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. Thatíll need to be replaced at Triangle Auto Service when it gets dirty.

Please ask your honest Chicago service advisor about your PCV valve. For the price of a couple of burger combo meals in Chicago, you can avoid some very pricey engine repairs.  Ask for Bryan or Paul.  Triangle Auto Service 4060 N.
