Hey all,

Well I got my injectors seated into my rail and I reused my old O rings. I did not fit them into the car yet though. After reading, alot of people are saying not to reuse the O rings.

Problem is I cant find them and apparently Nissan charge half a penis for them.

To confirm, are these the parts I need?

"O-RING HOU LWR" - 16618 - 53J00

"O-RING HOU UPR" - 16618 - 10V05

Ive still got the rubber seats and the spacer shit, I just need to small and big O rings.

I found a few shops on eBay selling sets for silvias(in 4's) for a pretty decent price(I recall 10.60 for the item + about 10 on post). Is that my best option?

These are the links, if anyone can confirm these are the parts I need ill hassle the seller to make me a kit of 6.

Also found some EFI shop in Melbourne which I contacted but not too sure if they got the parts I need. If anyone has dealt with them or what ever, please let me know.

Yeah it's sad Nissan charge either 6 or 8 dollars a seal which is f*ken ridiculous you could try efi performance they do seals can't remember how much tho also places like auto barn sell generic injector seals you take your old ones down an they match them up I payed 2 dollars a seal from there

The o-rings are a special type that doesn't break down over time with fuel hitting it. That's the reason they would be expensive. I re-used my old ones on my nismo 555's purely because it was Christmas and I would be without a car for a few days without injectors. No leaks so far, but I have a front facing plenum so if they do leak it's not hard to take them out and fix them.

If your desperate you can check your current o-rings for defects and if they appear ok then they may (I'm not saying definitely) should be ok to re-use

What to look for. Make sure there are no cuts, pinch marks, tears etc etc anything really that makes you worry either don't use it or put up a photo.

The o-rings should be a bit soft. Fuel o-rings are a little harder then some o-rings but if you can squish it a bit it should be fine. If it's rock hard and doesn't stretch etc then it's no good.

That is if you want to re-use what you have. It's a pain to fix if it goes wrong and you have a standard manifold but lol. Id keep that in mind

In the case of rubber, when I was talking to my mechanic (nissan specialist), he said the difference between genuine Nissan rubber (cam seals in particular as I had him do my 100k service) and aftermarket rubber (Gates) is significant. The Nissan cam seals are nice and soft whereas the aftermarket cam seals are rock hard, I'm not saying which is better for that cam seal application (hard vs soft), just pointing out quality difference what is supposed to be the same part.

    • Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
