Yes, it was the same with my mate's engine ... receipt from a garage for a VEGE engine with a recorded 250 miles since fitting ... the owner had shuffled off his mortal coil and his wife left the van on the drive to rot away. Justin bought it for the engine given the receipt and lack of miles but the van and the engine was a write-off. The cooling system was blocked with strands of light blue silicone One bank of barrels had 'Good side' written on them in permanent marker pen and there was other assorted bodgery which had occurred to one head .... so much for the total recondition.

Garages receipt is not proof in my book that this was agenuine VEGE recon
Garages probably buy from some middleman who may have told them what they want to hear.
How often do you see OEM describing parts that clearly are not.

My take is, it's under enormous tension, but without even tension, (like this stud got over torqued) the stud will flex/stretch more than its specified value.
This would result in metal fatigue over time and ultimately a fracture would develop across any flaw, the tension would accelerate this process.
Which would be perfectly acceptable IF applied correctly. It forms a gasket if lightly applied and the two faces brought together but not tightened until set. Once set and then tightened correctly it will have formed the gasket. I have yet to see a correctly made silicone gasket when I have dismantled items, everyone seems to slap copious amounts on then immediately tighten it up ( which of course then leaks!) squirting it everywhere. It has its place in the right hands.
