Yes it did.on top of the piston also.it was like it was baked on.Preignition which leads to detonation maybe.[emoji848]
Did it have a crap load of carbon in the ‘squish’ zone?
The carbon acts as a glow plug.

I had a similar one, but much more of the piston, you couldn't even tell there was a problem with it looking thru the exhaust port.That's an interesting failure. Any chance on some pics in the intake ports and exhaust port??
Yes Brett, This one is quite unique for sure. The uniform shape of the heat pits and mainly concentrated on the cylinder roof and piston OD. It makes you think fuel additive.
