Blowing oil out dipstick and oil pan HELP!!

Hey guys, thanks for the help on my other thread and after getting the car just about running i've found the problem. I have NO IDEA what could cause this but the engine is creating pressure not vaccuum. When i crank the engine i have no vaccuum and it blows oil out of the dipstick tube and out of the front of the oil pan, when i stop cranking i can hear pressure hissing out for another second. Could this be from a blown head gasket or something? Everything has new gaskets and seals except the head gaskets. Thanks for the help guys!!

christ it sounds like you got some crank case pressure going on.
Hmmm could be a few things but Ill take a stab dunno if you had the engine apart,
Cam timing out to lunch not sure on these v8 but on the stationary guy had his timing out and valve hit piston and put a bloody hole in the piston. wasnt pretty big mess.
See on the big engines all the time broken rings that one really gets the oil coming out the dip stick tube. Hole in piston cracked piston.

Should do a leak down test and compression test
