Pcv valve problems

[Matthew12M]

Hey guys

I got a 1988 c1500 5.7 350. I have been noticeing oil in my pcv valve and sometimes while decelerating the engine idles a bit low. I also have a little white smoke on startup. I believe that the white smoke on startup can have something to do with the pcv valve being contaminated with oil (even though its new) (and no I dont have any coolant leaks, its not the only thing that can burn white). Is oil supposed to even get on the pcv valve? I know its attached to the valve cover, but isnt there some sort of a filter where the pcv valve fits into the rocker arm cover that protects the pcv valve from oil contamination? I noticed some thick oil sludge in the compartment, and cleaned it out before I installed the pcv valve. Anyways, I was wondering if I could take the valve out or put a breather in its place or something. Or is there an oil/air seperator for the pcv valve? Or should I replace my valve covers? Thanks,

Matthew

P.S. (Im also contending with the idea of bad valve stem seals, but I dont wanna fix something difficult if I caan do a quick fix on my pcv valve.)

Are the head drain holes filled with gunk??
