what time frame/use/passes did that gear have ?
my thoughts are, where do the gear particles cause the most damage to the rest of the internals ?
beer


2.5 years, six passes and roughly 3k miles. Cold oil pressure would run 80 PSI. After the change from 20w50 to 10w40 cold pressure is something like 65 and hot idle is 25. Been checking the gear every Spring since and it looks like it's wearing OK. Don't drive the car too much anymore though.

No idea what the clearances are in the motor. Would have to find the paperwork from the shop.
