JB weld that sucker and throw it back together.

 

looks like it got a little hot...

 

That'll buff out...

 

Duct tape it and say it came like that!!
Surprised your heads look as good as they do really!

 

Gotta agree, little elbow grease. thats all u need.

 

Really good pictures. They show the damage that can already be done inside by the time it shows up on the spark plug. In all, you came out really lucky with the little damage you have compared to what could have happened.

 

how did this happen

 

#7 runs hotter than most on most engines. Ends up running lean and then...boom. Still kinda of a mystery as to why exactly. Good theories but no definitive ones yet.

 

Too much heat

Yah Not as bad as i thought it was gona be just some scratches and melted piston slag on the cylinder walls and the head, but the oil had alot of small debri in it and gray swirls so im not just gona slap it back together.... So Im gona have it bored 20 over and put all new bearings new oil pump... the works

Season is about over anyways
