PCV Valve Service at Mac's Tire & Auto Repair in Center Line

Posted May 8, 2017 2:40 AM

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 Mac's Tire & Auto Repair. At high speeds on MI 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 Center Line 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 Mac's Tire & Auto Repair in Center Line and quick and inexpensive to replace. Even so, it's often overlooked because many Center Line vehicle owners don't know about it. Check your vehicle owner's manual or ask your Mac's Tire & Auto Repair 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 Mac's Tire & Auto Repair when it gets dirty.

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

Testimonials

  • Honesty, What makes this place great is their honesty. I feel very comfortable taking my vehicle to Mac's knowing they aren't going to rip me off for repairs I don't need.
    -Cindy T.

  • Another great experience! I have been bringing my car here for service for some time now. Fortunately, I have a vehicle that has held up very well (209,000 miles and counting), but when something does go wrong, I know exactly where to bring it. Mac's Tire & Auto Repair has always been forthright and honest with me; they WILL NOT try to sell you something you don't need. My most recent visit required new brakes, rotors & calipers on the front end. This isn't a cheap job, no matter where you get it done, but I must say, I don't think my brakes were this good even when the car was new. Money very well spent. Keep up the good work!
