I think one responds was mising in this discusion and that is high volume oil pumps as if u have a 2 tight bearing clearnce u might not be able to tun high volums oil pumps and only a standarn pump as the the bearing clearnace didcates wieght of oil and what oilpump u run.............as lower bearing clearnce will need lower weight oil and not high pressure pumps to get it through the smalller clearnces were the higher beary clearnces not heavy oil viscoity and the higher voulume pump................if you disgree with plase feel and explain to me were my thinking has gone wrong.............thanks al..
main bearing with a 2 thou clearnce with use a standard pumpwith alighter oil like a 15-40 or a 10-30
mainberaing with a 3+ thou clerance with use a higher volume oil pump and higher oil like 20 50 wieght.................i have also that for every ten degree hotter u r installing your bearing grow 1 thou....................foood for though
