Injector O-Ring sizes?

[DaydreamDrifter]

Same as title. I've searched ofr the culprit of my smoking and I beleive its the injector seals. Anyone know the size?

I dont know the size, but 2BN_S13 just bought a injector rebuild kit that came with O-rings and a few other parts (maybe plugs?). Dont know where he bought the kit, but check out some sponsors like everythingnissan.com or Midway Nissan. I'm sure they can get you the correct size

thanks for the info, but i've changed my hypothesis and now i think the ecu is bad and is keeping the injectors open for 14 milliseconds during idle. which is way too much

actually, you can get an o-ring kit for those injectors at autozone for like 5 bux.

if you do replace the orings, make sure they are intended for use in fuel sysems. those NOT designed for use around gas will breakdown and leak double quick. get them from a dealer if all else fails.

why do you think the ecu is holding the injectors open too long? what other mods do you have to cause that change?

I was working at a mechanic shop as of this past Friday and i got him to look it over. He used some peice of equipment and read how long they were staying open. This may have happened as I was swapping ecu's and maf's and such before as the information as to what should be used in this swap wasn't clearly available. I may have miswaired the MAF back and possbily fu-ked up the ECU.
