vaccum problem???=blow by???
is it possible that a VERY LOW vacum can make a blowby problem... i have smoke comming off valves breether on a brand new engine. Still have this problem while hitting the gas. I dont want to tear my engine apart if it could be a little problem.
i have a prety wild cam

mine was doing that. it's normal i guess. i just hooked a pcv valve to mine. it should get worse when you get on the gas. thats not too wild of a cam. and has nothing to do with blow by.

Re: vaccum problem???=blow by???
Your TB? Is this TPI still? How'd you tune your ECM for that cam? Think it might be running rich?
Lack of vacuum can cause your PCV to not work up to snuff, but that shouldn't make the engine smoke more. What did you gap your rings to?
Most importantly, how'd you seat the rings? HARD?

Re: vaccum problem???=blow by???
think i fixed a part the problem...i have no much smoke off valves covers... i did'nt plug the vacum hoses the right way...i blocked the vacum hole under the TB (lt1 intake) and it was the pcv vacuum hose...but still oil comming off dipstick ans oil distributor...
