Morning all, probably pushing my look for a long distance diagnosis, but here goes anyway. Original symptoms where a knocking at the top rear of the engine and smoking heavily on acceleration, resulting on a tow home to make sure, just in case. First diagnosis varied from piston slapping, broken injector, damaged valve or valve spring With now the head off no damaged valves I can see straight away,(though the head is going off for testing and valves recut if needed) but, all piston tops are clean with just s light carbon film that cleans off..however..No 6 at the back, where the noise seemed to come from is damp and has what looks like small peck marks all over the crown.
Broken piston rings anyone..?
And.. Pull the piston out from the top or through the bottom, if so anyone pulled these before .?
