2002 So I am right on the cusp of the transition to the new jet bolts. I've seen some discrepancy on the transition numbers/dates. Additionally I have read that the bolts will fail regardless, and have read multiple posts of engine failures having the symptom of failed oil jet bolt 'valve' failure. I figured they're worth checking even if my engine number post dates the transition to the new ones.

I'm with you on that preventative maintenance crew. Since you're already taking care of the banjo bolts and retainers, what about a Billman TCT to top off the AP1 preventative care trifecta?

Already been in contact with Billman

The banjo bolts are a risky procedure, so just make sure you actually need to replace them. And needless to say, be very careful if you do decide to replace them.

The banjo bolt related engine failures that I have heard of were from extended 6K+ RPM use on derestricted roads. Like...constant high speed use on the German Autobahn or something.

I was looking into this. Most of the problems I saw were from using 3/8 inch torque wrench instead of 1/4 and stripping the threads. Have you heard of any other problems while replacing?

Nope, no other issues. Just user error. A stripped thread will mean a bad day.

Cross threading is common on the banjo bolts. Even seasoned wrenches can have difficulty with this job.

Do ap2 retainers and ap2 cotters.

I recommend you DO NOT do the oil jet bolts, unless you plan on future forced induction.
