    performing a leak down test .....

    Intake plugged up with three squeeze plugs, racquet ball wedged in the exhaust manifold. Rear oil fitting pluged, am I supposed to be getting vacuum to the front oil fitting? Because I am, I thought that was sealed off from the rest of the engine? When I run a single oil line between them it holds vacuum for a good 10-15 mins. Do I have a crank seal blown or its supposed to do that.

    Thanks guys

    Nope, that is correct. There is a check valve between the balance shaft oil resovours and the crankcase cylinder 1 and 3
    Thats why the carb oil fittings provide less oil to 1 and 3 because the rest comes from the oil fed the front and rear housing and why you must fill them before running the engine.
    Sounds good to me.

    Thanks splash,

    So with that being said, my check valves are in working order now after applying vacuum. Because the front fitting wasn't leaking until about a min into holding the vacuum. Heard a slight pissing/hissing sound and thought aww shit!
