But... isnt it a problem trying to stuff molasses into a tight bearing clearance? it just wont get in there and the bearing will starve. I understand what your saying about rotational pressure... BUT, I still disagree that feed pressure isnt important. To keep plenty of oil in the bearing when its getting pressed out at high RPM it requires good feed pressure right? otherwise performance engines wouldnt be so concerned with such high oil pressure right?? I do agree that proper lubrication our engines dont need the pressure they have when new, but without it the engine will wear down to insufficient pressure long before they reach end of life, and if they dont have it because a bearing is loose the bearing will hammer out the case and make things even worse.
