Question

I have a 68 camaro w/ a 350. The previous owner has the pcv valve drawing vacuum off of the carb, and my valve cover breather is blowing oil. It has an Edelbrock manifold that has a (i believe) vacuum source that is capped off. Is this where I should run the hose to?

Cool

If it is an Edelbrock carb, the pcv should be hooked up to the large fitting on the base of the carb, same with the holley but on the corner I believe. So it sounds like its hooked up right.

Is the pcv valve clogged? Do your valve covers have baffles in them? I wouldnt think the pcv valve would cause oil to come out the breather. Usually if your pcv is clogged you will get a bit of smoke from the breather.

I'm sure someone will come along and give you a better explanation and answer. Sean

I had the same problem on two separate engines. Both of them run a pcv with a breather on the other side. I was using billet style aluminum covers on both. These engines both have leakdowns of 2% or less but they still dripped oil from the breathers after a "pass". After several different styles of breathers I installed the Edelbrock tall chrome valve covers that have an oil baffle like a stock cover. They have not dripped since. I did try the baffled grommets also but I guess at 6500 rpm there's a lot of oil splashing around; the new covers solved the problem.

Thumbs down

if your cranking the engine above 6500 you should have crankcase evacuators from moroiso. i don't care how much leak down you have on cranking it thats not statick compression

I lost you Devil's Lake; you don't crank the engine to do a leakdown. Since I've eliminated the problem I don't think I will change. I thought about the Moroso deal but with a full exhaust I don't think it works as well at normal rpm's which is where I am most of the time.

If you're running the Moroso style evacuators you wouldn't see any oil being pushed out; it would go out your exhaust.
