Just stripped down top end and found this.The hatching marks have worn away in parts of the cylinder,and looks like evidence of tightness on the piston.Would a deglaze with one of the 3 pronged deglazing tool be sufficient to bring things back or would it need a hone?

evidence of a light seizure would be more likely :-(

Whats teh piston to bore clearance??

Nice porting. Is it your own work?

No Knowledge its an MB tuned TS1 240,sprint motor.Done in 2000.34 hp.This is why I need the advise to keep cost down if it needs a lot doing as in rebore etc.

Donnie the clearance is ok had it checked a while ago.May be heat seize.Its from my sprinter,prob got too hot waiting in line,but surprised the hatching has gone.

That looks more like scoring from grit particles being digested....dusty paddock maybe?

Possibly as I run an open carb coaster.So whats the best course of action,a few runs of a deglazing tool and clean up the piston with emery paper?
