Will replacing PCV valve Stop oil leak?
It’s a pretty simple system that does an important job. The re-circulating air prevents sludge from entering the crankcase. PCV relieves pressure in the crankshaft, allowing the oil to flow more freely through the cylinder.
In addition to this, it also helps to keep your engine cool, which is important when you’re driving at high speeds. It’s also a good idea to have a fresh oil change every 3,000 miles or so, just to be on the safe side.

What causes PCV valve failure?
The pcv valve is exposed to extreme temperatures and pressures over time. Prolonged exposure to these forces can cause these parts to swell, stick in place, or even grow brittle and crack. This can cause vacuum leaks, which can lead to engine misfiring and damage to the engine.

This system is called an air-to-air intercooler, or A/A-I. First, you can look at the car’s odometer.
If it shows a mileage of more than 20,000 miles, it’s likely that you have an engine that has been modified to run on gasoline. Second, if you see the word “PCV” on the engine’s owner’s manual, that’s a good indication that your engine is running on gas.
