East Greenbush Drivers: Is It Time to Replace Your PCV Valve?

Posted June 26, 2022 10:44 AM

drive

The crankcase is the lower part of the engine where the crankshaft is housed and where the engine oil lives. The crankshaft is connected to the pistons that power the engine.


When you are diving around East Greenbush, fuel is burned in your vehicle engine, it pushes the pistons down and the crankshaft rotates and sends power to the transmission. Some of the explosive gases from combustion squeeze past the pistons and down into the crankcase.

Now this gas is about 70% unburned fuel. If it were allowed to remain in the crankcase, it would contaminate the oil and quickly turn it to sludge. Sludge is like Vaseline and clogs passages in the engine, leading to damage.

Also, the pressure build up would blow out seals and gaskets. So in the old days, there was just a hose that vented the crankcase out into the air. Obviously, not good for our air quality in East Greenbush, NY.

Enter the PCV valve. It's a small, one-way valve that lets out the gases from the crankcase and routes them back into the air intake system where they are re-burned in the engine. Fresh air comes into the crankcase through a breather tube. This makes for good circulation in the crankcase. And that gets the air out. As you can imagine, however, the valve gets gummed up over time.

Your vehicle manufacturer usually recommends they be changed somewhere between 20,000 to 50,000 miles/30,000 to 80,000 kilometers. Unfortunately, PCV valve replacement is left out of some vehicle owner's manuals, but your friendly service advisor at Pro Tech Tire & Auto, we will make sure your PVC is replaced if needed.

Testimonials

, 06/20/2022
My husband and I experienced a blowout of one of our trailer tires on the highway. With traffic speeding by at 70 miles an hour my husband got ready to change the tire. James from Pro Tech happened by and parked behind us in his truck with lights blinking to help let oncoming traffic realize we were there. While he couldn't stay the whole time he did let us know Pro Tech would have a replacement trailer tire so that we'd still have a spare. When we got to Pro Tech James and Mike (the owner) helped us get the spare back in place, removed the blown tire from the bed of our truck and checked out the damage to our trailer septic system. Zip ties were applied to keep the remaining piping from dragging. They went above and beyond to help us and we were able to continue on to our campground 2 1/2 more hours away. Thank you!!!!
