Convert from oil breather to PCV?
Hey guys,
Car is a 1985 Camaro IROCZ, 350 engine with roller valve-train, TPI. Issue is described below,
The problem is the previous owner of the car installed a high volume oil pump and the car is leaking very small amounts of oil after driving it. I believe the issue is that the oil pressure is waaaay to high, the pressure gauge it basically maxed out. The previous owner also told me that if the car was driven really hard, it would push oil out (not really sure where, and I can't tell where it's coming from). Anyways, the prev. owner told me he had planned on converting the valve cover breather to a PCV valve.
Does anyone know if converting oil breathers to PCV will reduce the oil pressure, or is this even possible to do with a 350 TPI engine...and if it is possible, how would I do it? I will post this on a new thread because I am guessing no one will see this post, thanks in advance for the advice and guidance.
When I had the car in the shop to have the rear diff seal replaced, the mechanic told me the oil pan gasket was good, so the leak was likely coming from up higher. I wish he could have pinpointed it right then and there...
Also, this is the first time I have owned a car with valve cover breathers, how often should they be replaced?
Right now the car is in storage, so I won't be able to do anything until the spring.
Cheers,
Mike

Just addressed this in your other thread, but here it is again.
Oil pressure is internal and isn't going to cause an external oil leak, but a poorly vented crankcase will. Hook up a PCV valve to one valve cover, and leave a breather in the other. Doing this will have the PCV sucking out crankcase pressures, instead of it blowing out naturally on its own. Some people view the PCV as an unwanted emissions item instead of something that's actually good for the engine to have.
