i need some help, i just rebuilt my motor and I got it tuned. Then 500 miles later smoke started coming out of the breather when the engine is under a load. I did a couple things,I compression tested it all 160 to 170 psi. I also got a new pcv and also realized there is a little shaft play on the turbo. I dont know if that's what's causing the smoking? No CELS.. what else could it be???
