..gotta let it break in good and baffle on the pan deal is a must. Might take a couple hundred miles to break in REALLY good....depending on ring material, bore prep and tolerances....

Any chance the PCV valve is in backwards? This could make your crankcase pressure high, which would put pressure on all the places oil could go, resulting in the condition you describe. Sometimes I ask dumb questions...
If you have oil sucking into the combustion chamber, and coming out of the breathers/valve covers, then something is not right. Are you using a stock type PCV system i.e. passenger side breather vented to air cleaner base and pcv to manifold vacuum? Did you do a leak down test and see if the rings have excessive blow-by? Without seeing the engine in operation, I'm not sure which of these is your problem, but do a leak down test first and eliminate one variable, then look at the others. |

Nobody would want to wish he has a bad engine! Nobody said anything about bad rings! Now if you read the name of the thread it says, " crankcase pressure up the yang yang!!!". Now what would cause that? And although I'd love to see the problem as simple as a PCV issue, I'm going by the initial info given. If you want to rule out the PCV just put a vacuum cap on PCV port and take it for a test drive, see if it still smokes on decel (throttle shut down).

According to the OP, the crankcase pressure came when he disconnected the PCV.
