The bracket looks attached to the pan.

yes it does look that way, it is deceiving though , if you can remove the two lower bolts the bracket separates from the compressor and you are left with the small bracket attached to the pan while the compressor is left in place.

interesting.... My block number is 1025223, built in April 2002. I always thought i missed out on the upgraded bolts, but now I have new hope! I'll have to check this out and let everyone know.

according to this, yours are upgraded already

I'd advise that you don't count on it. Just as engine #s don't always match chassis #s, there's no guarantee that the part #s always correspond to engine #s. Engines would have been assembled and tested in batches (or in parallel production lines if you will), and it's possible that some batches with the 2-hole bolts got stamped with higher ID numbers than other batches with 4-hole bolts.

I'd actually be surprised if there was a single clean cutoff point, where every engine below that # has the 2-hole bolts, and every one above it has 4-hole bolts. For the purposes of the TSB, Honda will have simply identified a point where they're sure that no "straggler" 2-hole motors were left.

Until you actually check, you'd be wise to assume that if you're under Honda's official cutoff, you have the 2-hole bolts.

Unfortunately Honda has no "official" cutoff point, the last number of xxxx5376 was simply the last reported engine where the owner found 4-hole bolts (prior to me finding mine). In North America Honda was completely "mum" on the subject and wouldn't even confirm that the issue of 4 hole vs. 2 hole bolts even existed. This is my biggest complaint of Honda with respect to the S2000, they just wouldn't discuss the issue in North America.

Jfusion...

I actually got Honda to warranty an engine for a guy based on the oil jets. He had a genuine number 4 cylinder failure. I got the official recal letter from a guy abroad, it was in dutch, and I had it translated.

The car was topped out on a long road at 154mph for 90 seconds or so. Think about that. This is hard to do in the USA, unless you live in the desert.

I told Honda I would prove this and I also told them I would not tell anyone about our arrangement. Well its been many years so the dust has settled. They hated me at first but now would love to have me work for them I am on great terms with them today.

That is pretty amazing, that guy was lucky to have you in his corner. I'm willing to bet a few owners weren't so lucky and got the raw end of the deal from Honda. I just wish Honda came out and said the bolt changeover happened on such a date and after such a VIN #, and acknowledge the event.

I think it was earlier than August. By then 2003s weren't far from hitting dealerships. My '02 was built in June 2002, I took delivery in July, and it has the 4-hole jet bolts (based on the engine #, I have not verified this visually).

Yeah there are is a lot of incorrect info out there, apparently the person who quoted the August 2002 date was a forum member who was affiliated with Honda, obviously he was wrong. My build date was April 2002 and my car had 4 hole bolts. They likely started even earlier than that though, we just need others to confirm it.
