is a man of many talents
When I was helping a mate build supergas drag car engines, supercharged big blocks engine in a full road chassis, circa 1500 hp, we used permatex ultra cooper spray on any MLS gasket that didn’t have viton facing, also used it on other lesser engines getting composite gaskets.Finally was able to sort out my air in the fuel issues today with the tractor. One of the olives on the steel line returning to the secondary filter was worn out and loose. New lines got it sorted and there's no air at the 4th injector line.

But, give it some throttle and the dreaded white smoke is back. Slight miss in there as well but it revs up spectacularly...but smoky. And I've no real clue what else could be wrong. Unless there was a compression issue...
And then I start to hear it as the tractor warms up and at the sort of revs you use when running attachments via the PTO. A light, sharp, squeaky repetitive banging. Chasing it down with earmuffs on did the trick. The head gasket is blown at the back of the engine on number 4 and oil/diesel/whatever is squirting out....
Looks like I'm going back in...
Helps deal with surface imperfections too, while it’s easy to face the head, dealing with a block deck that’s rough was always a PITA.
The ultra cooper will make it a PITA to pull apart in the future, so much so one trick was to mount slide hammers to the head to get it off.
Fingers crossed it hasn’t turned a block thread into a slinky.
