We've also had issues in the past where the oil scavenge pumps have bolts that loosen up as well. Sometimes they can be tightened up and it works again, but often they are junk when they fail.

Others may chime in here, but I think they typically have a life expectancy of about 30,000 miles.

I dont onow how but i got 65k out of mine. It start stopping working on the motor side when it got hot. And the lil tabs with springs that push against the main rod were to worn out to be pushed more
