Hi all, Im having excess oil issues in my Z06 road race car. Its a 2002 Corvette with a 383 stroker mild build. I do believe it has a hi volume oil pump. I do get excessive blowby at hi rpms (just the way it is)and I have 3 catchcans all over the place, thats not so much the issue but valve covers getting loaded with oil and filling up catch cans, as 2 of my CC's are plumbed off valve covers.
She has a Crane Cam, specs unkown-but not huge, OEM pushrods, rockers, but dual valve springs.
Would a oil restricted set of push rods help here? THX all!
Years back when we had a 350 or 383 with too much oil going to the valve covers, from using soil lifters with a flat tappet camshaft, and hi-volume oil pump. I was told by an engine builder to put restrictors in the oil galley`s feeding the lifters in the back of the block. Had no issues. Used 2 restrictors, 1 per side.
Yes that can restrick the oil flow. The fact you have excessive blowby could be concerning. Loose, worn or broken rings could cause excessive blowby,along with excessive oil in the valve covers could be messy. I can see your concern, Maybe a different breather catch can plumbing system might help also.
