4th oil change on new motor, previous ocis after break in approx, 500km, 2500km, 2500km.
3 previous oil changes before this Zrod were Lucas 10w30 Hot rod oil. Did not get them analyzed as didn't want to do analysis on such short OCI's on a new motor as probably still flushing out contaminants from the rebuild.
Went 5958km due to 3000km summer roadtrip over 1.5 weeks to the Bonneville Salt Flats for speed week in August from BC, Canada.
Wanted to check up on this rebuilt motor done 2 years ago, and looks like some bearing wear.
Is this normal on old domestic motors? We will have to chart a trend with the next UOA I guess.
Or could the motor still be breaking in? It has plenty of oil pressure, 30-40 psi at hot idle. 75-80psi during warm up. No knocking or power loss. Baldwin B2 USA made filter.
Tore oil filter apart and no sparkly stuff or magnetic stuff in filter.
