Yesterday was on the freeway and was boosting 14psi at full throttle. It reached 14psi then had a smoke screen coming out of my exhaust. I am running a built head on a jdm gsr motor with a greddy kit and an open header / cutout set up. Note: i have this tuned on 14psi making 273whp on hondata s300.

I lose oil pressure and after getting the car to the pullout on side of the freeway. i pop the hood. oil is all over my valve cover and all over the exhaust manifold. i am unable to start the car since the motor doesn't turn over anymore.

So is the motor blown or just a headgasket. having it towed to a shop for a rebuild.

 

no oil pressure = increased bearing clearances somewhere.

the possibility of it pushing out the gasket around the oil jet is not likely.

if you have no oil pressure, take it out tear it down.

 

was torn down. found that i had cracked my cylinder walls and on all four cylinders but a massive crack on #2 cylinder.

so as of now, trying to source a new block. wondering if i should go find another gsr block or get a b20 block and new pistons.

 

Depending on the damage to the cylinders you may be able to just re-sleeve the block. Which block is it?
