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.

It would be a nice for us the have an estimated MBTF for some of the key parts in the HPF kit so we can add them to a Maintenance schedule for r HPF cars.
