Oil

Quite respectable with factory tolerances. Would probably also be just fine with 10-30, ‘cause you don’t need 45 psi at hot idle.

Interesting, I started my engine yesterday, about 35ish degrees , (not sure) . The oil presdsure was slower to come up than I`ve ever seen , and climbed way slower than I `ve ever seen. I let it get to operating temp on the gauge , and the pressure still dint come up to what it usually does. It has recently new 15w40 in it , from a main seal cap change .
I had a hair over .002 clearance when I put it together about 8ish yrs. ago . Hoping I didn't hurt the bearings , ether need warmer weather or lighter oil !
