It has 25psi compression, and 99% leak down on #8. So what is needed to fix the car when it drops #8? I was quoted $9800 from brenspeed to fix it and I'm not interested in going that route, because I want to trade the car in at some point. Is it able to be fixed by just replacing the rings, and maybe the piston? If the cylinder wall is bad couldn't that just be sleeved?
