Re: Crank Case Pressure oil leaks ?? Help

Gary,

Just my opinion ...... I think you are wasting your time looking at the pcv valve for an answer to your oil leak issues. If it was a crankcase pressure problem you would be puffing smoke from the breather or pushing the dipstick out of its tube under load. You should be able to remove the pcv valve completely and run 2 breathers and still not have an oil leak. How many race engines do you see with pcv systems on them ? Do they leak ?

Same with the high pressure pump .... it will not cause an oil leak except for at an oil galley plug that is not sealed correctly.

What you have is a leak ..... you need to find where the oil is leaking from and fix the problem. Simple as that.

Start out by buying a $5 bottle of leak detecting die at the parts store and a $6 UV light bulb from Wal Mart. Put the die in the oil, drive it a few miles than use the light to see where it is leaking from. You would be surprised at how far oil can run, or get blown around an engine before it decides to drip off. Your drip in the back could very well be from a valve cover gasket at the front of the engine. The die glows bright yellow and allows you to see exactly where the oil is coming from.

Forget about the PCV valve .... fix the leak.
