im asking for maybe some insight on the problem that occurred in my engine, there is noticeable scrapes along the front and back sides of the pistons, as well as the cylinder walls... also, there are 2 or 3 pistons that have small *****s taken out of them, like maybe a valve hit them?????

any insight is greatly appreciated

 

detonation...damn that sucks sorry to see that

air/fuel mixture problem most likely

...just another bump in the road!

 

Boosted engine?

 

i dont see any chunks missing in the pics, but if there are missin pieces, its detonation.

as for the scrapes on the sides of the pistons and walls, its due to overexpasion of the piston, the tune was too hot.

yea i just lookeda t the pics again, detonation

got pics of the cylinder walls? how bad are the scratches? does it catch a nail?

if i doesnt catch a nail, u could probably rehone the walls and run the same bore again

 

yea it scored the cylinder walls, i just decided to go 84mm anyways, its a sleeved engine. the scores dont hit catch a nail
