Hi,

one point to mention: The normal engine oil level is below the bearing if the car is standing on a leveled ground and the engine is off. It is under oil if the car moves, or not leveled, especially if the car accelerates. In corners the oils swaps to the side of the engine. So the oil level might be below the bearing.

The main problem in my opinion is that the sealing rubber of the bearing loosens plasticizer while the motor gets warm and cold over the years. Old, used oil can enhance this effect. The sealing rubber gets brittle. Oil walks through the rubber and washes out the bearing grease. The bearing gets pitting and fails in the end.

It's good to change engine oil regularly (recommend yearly), because old used oil is much more agressive to rubber sealings.

Regards from germany
