Three easy questions... 1. If the PCV system is working correctly. Is it normal to have the inside of the intake manifold coated with oil?
2. Is it normal for smoke to come out the rubber grommet when the PCV is removed from the intake when the engine is at full operating temps..
3. When the valve cover is removed. Is it normal to see smoke coming from the top of the open head when the engine is at full operating temps?

Not necessarily.. At operating temps (even when shut off), it is somewhat normal to see a bit of smoke come out. I wouldn't necessarily say a stream of smoke or something, but evidence that it's hot as **** down there. Oil does some crazy things under hot conditions.. Who would have thought

Thanks for the respnses guys.
I am confident in saying that when I have had the valve covers off in the past with the engine running, it did not smoke at all. So something has changed.
Is there any chance a head gasket failure could cause problems 1&2?
I dont seem to have any white smoke from coolant burn.

If I have a head gasket going bad. Could you see it being related to the oil in the intake problem?
To be honest with you everything you said up there is normal. The little oil coating is normal in the intake....these cars tend to do that. Also as for the smoke....thats normal as well.......its just a bit of blowby as long as its not excessive I wouldn't worry about it. Both my 355 and my 385 had the same deal....I ran a crankcase vacuum pump and I would always have a bit of white condensation vapor comming out of the catch can.
