Hi Finn, in my case and many others, the oil pan bolts are actually holding the engine in-place.
A sub-plate of aluminum is sandwiched between the block and oil pan; engine mount attaches to aluminum sub-plate.
Does this not mean oil pan bolt tightening is more critical?
Do all engine vibrations distributed from block to sub-plate get absorbed by the rubberized Lord-Mounts?

If you clean both mating surfaces with alkohol and be careful not to get
any oil or grease on them prior to applying the permatex, I think you'll
find it very hard to pry them apart later and have an oil-leak-free
seal. No big pressure needed from the oil pan bolts, if you tighten them
in a round-robin manner, slowly enough to let the permatex squeeze out.
