Massive oil leaks.

I just called Mazzolini and he says the 50-70lbs of pressure probably didn't cause this but only having one breather may have done. Anyone thoughts?

dude, you have no crankcase ventilation. it built up pressure and relieved itself wherever it could. probably the dipstick tube, and other various places.

my 440 has 85 psi cold, and I don't leak a drop
