PCV Valve Service At Tuffy Grand Haven In Grand Haven

Today, we are talking about your PCV valve. The PCV Valve is a little, inexpensive part that does a big job for Grand Haven auto owners. PCV stands for Positive Crankcase Ventilation.

The crankcase is the bottom area of the engine that holds the oil. When the SUV engine’s 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.

It can also cause SUV engine corrosion, something we see occasionally at Tuffy Grand Haven . At high speeds on Grand Haven freeways, the pressure can build up to the point that gaskets and seals start to leak.

Back in the old days, auto makers 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 SUV's engine.

This is much better for air quality and improves fuel efficiency also. (Budget-conscious Grand Haven 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 efficiency.

Fortunately, it’s very easy to test the PCV Valve at Tuffy Grand Haven in Grand Haven and quick and inexpensive to replace. Even so, it’s often overlooked because many Grand Haven auto owners don’t know about it. Check your SUV owner’s manual or ask your Tuffy Grand Haven 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 Tuffy Grand Haven when it gets dirty.

Please ask your friendly Grand Haven service advisor about your PCV valve. For the price of a couple of burger combo meals in Grand Haven , you can avoid some very pricey engine repairs.
