The bearings were inspected and plasta-gauged at the time... I do not recall a # but I called the builder and the clearances were accurate with his records. He stamps the block and can look up the build sheet. The builder started the motor on a test stand and broke it in; only way he would stand behind his work. I moved, and the 90 days has long expired since the original light off.

Started at the 5W-30 and am now at the 10W-30. I did run 20W50 in it once just to see and do not remember it having a “WOW” type effect when hot. I guess I need to pull the motor again. Several K in the machine work and parts, and I am thinking I would like to keep the parts inside the block, or the bearings in place.

I am not happy with 45 when the motor is designed to pull 6K RPM. I believe the rule of thumb is 10 psi/1k in RPMs’.
