Getting the Wheeling Fever

My Buick V6 conversion runs well and does not seem to burn oil, however, it's leaking from pretty much every gasket and seal there is. My crankcase pressure seems to be quite high. Oil is not just leaking out of the valve cover gaskets - there are tiny droplets spraying out and getting on the wires. The PVC is new, there is a breather cap on one of the valve covers. Smoke comes out of the breather cap when I shut the engine off. What else can I do?

Body Damage is Cool

Have you checked the vacuum line going to the PCV valve to insure that it isn't clogged?

Where does the pcv empty? If into the breather I would take it out of there and put it to a positive vac port. I may even take the pcv out and run a direct hose to a vac port. Several Jeeps I have had I put BOTH hoses from the valve cover to a vac port to stop the internal pressure...it worked fine. Also that breather may be clogged replace it with new or soak it in gasoline a while to melt the crud inside it.

Sorry for the slow response. Computer crapped out. The PCV went from one hole in the intake manifold to another in the manifold. I moved it so it goes from the back hole in the manifold to a vac. line in the carb. Seems OK. Thanks for the help.
