Well I got a friend to do a compression test on the motor and 3 cylinders were at 60 lbs, so the heads were removed and it looks like the rings were bouncing and start to wear them selves out, they piston walls look like a hone will fix them. To say the least I am happy to not see any broke rings and scratched piston walls..I think maybe an evacuation kit will be installed on the refreshed motor.
