When **** hits the fan

OK, so that may have been crud due to the poor seat/valve seal and the hot gases coming back. Seems logical. I was just wondering of some oil made it into the chambers and helped the detonation fun begin.

Those piston tops sure look 'clean' around the edges. Is that normal for this engine?

Yes, normal...lol...
No one else runs these and no one yet is posting any pics of a 8k mile run build that had coolant and oil blow through it after a piston disintegrated
The burn is central, it's a dish, fuel comes round that way from the int port, all I did was wipe the coolant with shop towels before taking the pic... some tan was wiped but that's air fuel path following the cylinder wall...thats how it works... the air follows or it breaks up and diminishes. Like a guide.

Carbon build up, it affects us all.
