That's too bad. It's usually the most simplest things that go wrong and get amplified with the lack of common sense and forgetting that almost anything will follow the path of least resistance.

Man... I read all of that and as you said... a lot of smart a$$ comments for a simple leak test. A lot of people fail to realize that combustion engines, no matter how well engineered, have slop in them, and that engines at rest will have looser tolerances all the way around compared to an engine that is working due to the process of heat generated. People forget that things expand and contract with temperature changes.

Mine just did this last night on a 29PSI pull. The dip stick is still good no puking, lucky me!

no when u do a test take off the cap or it will pressurize the crankcase which possibly couldve broke oil cap seal.
