This is false information. All rear main seals do not leak.
What is the main bearing clearance .0015-.003. So the crank settles max half of those numbers so .00075-.015. If you believe that “theory” which I do not.
When the engine is running the rods and pistons are pushing down on the crank and so it’s loaded in the down direction anyway. Then when it sits gravity will pull the crank down, but not any harder that the forces when the engine is running under power.
NONE of ours leak.... because we test them as above.
