Ok, here is the $10,000 question: Should Babbitt bearings if properly installed hold up for a good amount of mileage? Reason I ask is I have had main bearing failure on a couple of motors. Mains on these motors were not peined, set up way too tight ( I had to back off to get the crank to be able to rotate). If I tried to set proper clearance but crank would also not rotate. Had to use a rear main cap from another motor because the rear cap was butchered so badly.


Ironically I have an old engine with extremely worn main bearings, perhaps original but not a piece of broken out babbitt in the entire motor.


I drive this car 6-7k year
