High oil pressure

My buddy has a old stamas with a alfa drive and 350 engin. He just put a crank kit and new oil line hoses on it. now he puts it in the water and it blew the oilfilter oring out. so he takes the remote filter hoses off and puts a filter directly on the block. It swells the filter up and blows the gasket on the filter out like right now! ( for a second like 80 + lbs oil pressure ) my thought is maybe there is a blockage in the oil line (from the new oil lines) and its stuck in the engin now. Thanks for your sugestions. I've had a couple, so bear with me. :D

Another questions. how doe's oil flow through a 350 chevy. (like a road map version please) from the oil pump out? Thanks!:biggrinjester:

Not good. Who did the work? If it is a shop bring it back.

Many years ago we installed a rebuilt engine for a customer. It had excessive pressure and blew the lines. As it worked out in that case the clearances on the crank were too tight. It needed to be re done.

Maybe the oil filter adapter is installed wrong. Not sure how it could be.
 
Adapter backwards causes the oil to flow backwards through the filter. No more internal bypass and the element is blown out into the can clogging the outlet. Oil pump rides up on the pressure relief.
 
Thanks,he never took the adapter off the engine, the hardware on the engine is from late 70s.
 
The hoses on the oil filter mount are on backwards. The filter has an anti-drainback valve in it so all of the force of the oil pump is going into the filter and no oil is going to the engine!
 
If it's doing it with the filter mounted to the block you have a stuck oil pressure relief valve or incredibly bad crank clearances. Either way, gotta come out and oil pan has to come off.
 
Thanks everyone. Yes he took the hoses and remote adapter off, its has a 2 bolt adapter on the block that was already on it for the filter. They had the hoses made at a auto parts store.

Thanks for your help guys. It was a cracked fitting that the oil filter screws on to. you couldn't see it without a mirror.
