The engine has 12 cylinders and its power is 104000 HP.
Every cylinder has 8 studs M85 which are very slack. I can move them with my hand ( when the nuts are of course not tightened)
Also the gasket between the 1 meter diameter liner and the cover is very soft. I can fold it with my hands
The nuts which are tightened with 2200 bar hydraulic pressure have no washers underneath
If one stud is not tightened not any problem or even two provided that they are not side by side.
Why not any washers, why very soft gasket, why slack studs, why static indeterminancy at the covers
