Great new oil/coolant problem today!!

How long was the system pressureized during the cold test, and how much pressure drop was there? As mentioned in post #14, the intake gasket can leak internally. How long has the "catch can" been installed?

How long should I leave it pressurized during a cold test? The catch can has been installed since about february. Should I go ahead and work towards replacing the intake manifold gaskets again?

First you need to determine if there is a leak. If so, then determine what's leaking. Don't just throw parts at it until you know what's wrong. Provided the engine is cold, it should hold pressure indefinitely, but for the purpose of this test, usually 15 minutes is long enough.

I'm quite sure that a gasket is not broken. I've figured out that it is just condensation (yes ZL1 you were right!! Thanks) in the catch can. It sure is a lot though. At least 1/3 full in a couple of days. Cooling system pressure checked out normal. So I think I'm done here. Thanks.
