The dead give away is when doing the blow down test is the air will come out the center of the oil air separator.
The pistons on this motor is weak.

Front crank seal shouldn’t be that hard to fix looking up the cost of labor and parts. Piston ring is a way bigger problem tho. Hope it’s not that. How much did it cost for u to get the piston rings fixed? Thanks
