So... my colt melted the groundstrap on cyl 3 spark plug. The car still ran but obviously stumbled when i got into it anymore than about 25 percent throttle, but otherwise idled fine and sounded perfectly normal...
Im pretty sure it detonated under high boost however. With that being said however i had 30 psi on cylinder 3 and i pulled the cylinder head after a compression test.
I Still have stock headbolts and a stock composite ORIGINAL headgasket on the motor and was getting some rust looking coolant which i hadnt had before... I didnt have overheating problems though.
Upon removing the cylinder head i found no obvious signs that the gasket was blown but i guess it could have been something i didnt see. Cyl 3 had no scoring on the walls so im not 100 percent sure if the ringlands didnt break though... Should i see atleast some scoring with broken ringlands or would i obviously see at the edges of the piston? Has anyone see the ringlands break but the top of the piston turn out fine?
Ive also flipped the cyl head upside down and filled each combusion chamber with alcohol and released pressure on the cams (close valves) and none of the alcohol leaked through from the valve seat area out into the intake/exhaust ports. The seats appear fine without removing the valves and the alcohol test indiciates they are ok
Am i lucky possibly? New hg and bolts and be done? Im expecting to see something majorly damaged here causing the low compression and im not...
