Hey, I'm wondering if my 02 AP2 needs the updated banjo bolts. My engine number that I got from Honda is F20C11024272. Last four of VIN #4291. Thanks.

The general rule seems to be that serial numbers prior to 5386 are using the older banjo bolts. This is not the confirmed cutoff, but your serial ends with 4272, so I would believe that you have the older banjos unless someone prior to you updated them.

Also, I think you mean 02 AP1

From my readings which includes this issue since the beginning of time:

1) your serial number is before the new bolt was available so you are at risk
2) if you are super or turbo charged you at risk
3) if you track your car over 105 MPH you are at risk
4) if you street your car for "long periods" over 105 you are at risk

I should note I have an AP1 with the old bolts. I sleep well at night. I am normally aspirated ( no SC or TC). While I do not track this car I do see infrequent entry to the 105+ area. Not for extended periods.

I don't think its so much 105 MPH+ as it is extended high RPM driving. The 105 number comes from being in 6th gear and continuing to accelerate. This will put you at a sustained high RPM. I had a rod bearing failure at the dragon due to none other than the OJB. I had full oil, and maintenance had always been on point. It was the only thing that possibly could have caused it. It makes sense too since most AP1's drive 90%+ of the dragon in 2nd gear between 7-9K RPM almost constantly at times (those that actually push the car).

You engine number says you have the old bolts.

The bolts can be identified without removing them, the 10mm heads are quite taller on the new bolts.

It would be cool to borescope them without removing the oilpan (go through the drain plug hole) never tried.

Not sure that you could Bill with the factory windage tray in the way. Otherwise that'd be a hell of a lot easier than pulling the pan, lol.
