PCV Valve Replacement

Posted September 13, 2020 7:17 AM



Hello CAPE CORAL, let's talk about your often-unnoticed but extremely important PCV valve. The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. CAPE CORAL folks know that sludge is one of the biggest enemies of your engine, clogging it up and eventually leading to expensive failures. Also, the pressure buildup would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.

Pre-1963, gasoline engines had a hose that let the  fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. (Can you imagine how polluted our FL air would be if every car had been releasing those poisonous fumes for the last 50 years?) Diesel engines are not required to have these valves.

The positive crankcase ventilation (PCV) valve routes crankcase gases through a hose and back into the air intake system where they are re-burned in the engine. Fresh, clean air is brought into the crankcase through a breather tube. It's really a pretty simple system, but it does the job. The re-circulating air removes moisture and combustion waste from the crankcase, preventing sludge. This extends not only the life of your oil but the engine as well. The PCV relieves pressure in the crankcase, preventing  oil leaks.


Eventually, the PCV valve can get gummed up. Then it can't move enough air through the engine to keep it working properly for CAPE CORAL vehicles. If the PCV valve is sticking enough, you could have oil leaks, excess oil consumption and a fouled intake system. If you experience hesitation,  surging or an oil leak, it may be a sign of PCV valve problems. Your vehicle's owner's manual may give a recommendation for when the PCV valve should be replaced - usually between 20,000 mi/32,000 km and 50,000 mi/80,000 km. Unfortunately, some don't list a recommendation in the manual, so it can be easy to overlook.


Many PCV system problems can be diagnosed by our technicians at Superior Auto Care . Fortunately, PCV valve replacement is both quick and inexpensive at Superior Auto Care. Proper oil changes will greatly extend the life of the PCV valve. Skipping a few recommended oil changes can allow varnish and gum to build up in the valve, reducing its efficiency. So now when your CAPE CORAL service technician tells you its time to replace your PCV valve, you will know what he's talking about. If you have had your car for a while and this is the first you've ever heard of a PCV valve, ask your technician to check yours out or call Superior Auto Care at (239) 574-2121.

What People Say About Us

    This was my first experience at Superior. Shane, the manager, greeted me, and listened attentively to what I needed done. In a timely fashion, Shane called me and shared with me what needed to be done with my car. The estimate was clear, and fairly priced. When I arrived to pick up the car, I was a little early. All of the mechanics, dropped what they were doing, to help finish up my car. The mechanics were very professional, personable, and quickly finished my car. This garage was an A+ experience. Oh, and the quality of work was superior!!

    My clutch burnt out on my VW Jetta on a sat. I had my car towed to Superior on a strong recommendation of a friend. Monday morning, Manny the outstanding manager had an super reasonable estimate for me. I told him I’m an Uber driver and needed my car fix ASAP as it’s how I provide for myself. With all the challenges of parts etc Team Manny got it done in a few days. He has an outstanding staff of Jose the mechanic that work on my car along with Frank. I strongly urge you to consider Superior and Team Manny for you car needs
