Pic of your crank? It may have wear. OEM bushing, right?Gonna wait for ideas..right now im thinking about using anaerobic sealer inside spacer bushing...On new replacement 440 crank it looks like the crank is thickened....but that is for 12mm wrist pin..mine is 10mm
Small leaks at seals can be tuned out (debate on this), but aren’t ideal. I didn’t pressure test the 044/440s I’ve rebuilt... no running issues, though.
Lakeside had a post about this years ago.
