i hope i am wrong being something internal , but lets see wht the compression shows , because all the air is flowing back to the crankcase not going to where it should to , which means this might be a burnt ring piston , but the car idles,fine,drives fine, no smoke , so not sure yet , i just hope its not with 1500miles only on the car , and the owner was on 7 psi only and a week only on 11psi , so no matter how beat on it it should have held it, it had 500 miles when he got it and he broke it in till 1000miles or so , so 500miles boosted miles .
