Lets make this thread as informative as possible. Information pertaining to this subject is in fact on the board, whether it is scattered (usually) or not. However, over time, one can add to the subject, especially with updated experiences with our cars.

So you may have heard of the banjo bolts, or oil sprayers that were revised in the newer ap1s, I believe in the middle of MY02. Please vote if you have an ap1 that was manufactured before the revision took place.

I know what a banjo bolt is but I haven't heard that there was a problem with them. My AP1 is a 2001 so I guess that means I need to replace it. I assume it's located on or close to the oil filter mounting (as it was on the MG) but what does the other end connect to?

If you don't plan on driving the car at 7000+ constant rpms for 2-4+ hrs then you won't benefit from the upgraded bolts, they say if you go turbocharged that they are a must though. I've decided not to touch mine and to leave them alone, 2002 MY with engine VIN # that is under the "reported" VIN switchover point. I have 59k miles on it and the car runs strong.

Didnt do the banjo bolt change.

at 80K miles.

From what I read, its mostly necessary if you're consistently doing high RPM/high speed stuff such as driving at 100+ for extended periods, tracking, or going FI.

Since I live where the max speed is 55 with no track (yet) I saw no need to change the bolts. I have them on hand, just in case I ever drop my oil pan I'll do it.

I have a MY00 and am beginning to to track here and there. Based upon this, I have chosen to get them replaced for peace of mind. I also think for the earlier years, this mitigates some of the shortcomings of the 2000-2001 vs the 2003-2003 AP1 and when and if I ever decide to sell, I'm sure this peace of mind will also be shared by the next owner. Makes sense as a viable upgrade to me.

No replacement

48,000 plus

No issues-meticulous maintenance

Many moons ago I had a friend that worked at the Tochigi plant (he used to be on this boarduntilit became "too commercial"). He indicated signs of starvation occurred with extended 100 MPH driving or tracking the car.

I would like to ask if the modification of the sprayers does in fact cure the starvation (while doing 100+mph)? or does it just "decrease the chances"?

it has never been confirmed, there is TONS of speculation, no one has a concrete answer sadly. What I would like to know is where exactly do you find this engine serial number? From what everyone is saying, and from what I have found using this spreadsheet that patinum has made, it is agreed that somewhere mid 2002 they switched over to new style oil banjo bolts. According to that spreadsheet it seems in that in 2002 there were 10,036 s2000s made, from this can we assume that any s2k with a vin #(from the dashboard) with a number greater than 5000 has the new style banjo bolts? I have vin#8386 so Iam wondering if I got the new style ones or not.
