sr20 fuel injector o ring? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Alright so since last mm, I've had a leaky injector. So im going to first resort to changing out both the o rings. But i've been doing some research and have come up with two different answers. Some say to use the o rings off of the kade rail, while i saw on a few searches that you use the 300zx tt o rings. I jsut want to get this figured out before i go out and buy them. Also when I go on autozones website to look for the o rings, they dont have anything listed for it.

so any help would be nice.

ka24de fuel injectors are the same o-ring part, make sure to get dealership equivalent parts

so my best bet would be to go to the dealership and get the ka o rings. also then why am i finding on zilvia and nico in so many places to use z32 tt o rings? this is confusing me so much.

Same thing also

Basically what you need is the O-rings for a Denso Side Feed High Impedence injector.

The Z32TT, iirc uses these type of side feed High Impedence style injectors as well, so does the B13 Sentra SR20, the KA24DE motor and even some mazdas and mitsubishi

ok thank you very much.

Alright, so i pulled the fuel rail and primed the fuel system and no leaks. So now im really wondering how fuel is getting in my oil.

rings or leaky valves?

clay9110 · 09-10-2009, 03:08 PM

Is there anyway to check those easily, also someone else told me to check my pcv valve. All i know is that this is getting frustrating to me. any help is appreciated.

Got it figured out. the gas in the oil wasn't from a leaky injector. my pcv valve was stuck open so gas was getting in while under boost.
