which grommet or air bleed to use???

Fidelity101 · 05-10-2009, 06:46 PM

I have an S5 motor in an S4 car using the S4 electronics and all that boring jazz, so I still use my S4 injectors but I am using S5 rails. so I ordered s5 grommets for my injectors since they were going to be on an S5 block/manifold with s5 rails.

on mazdatrix's website they have the grommets listed as

84-92 All Upper Grommet 13-2520-8574
84-88 All Lower Grommet 13-2570-N326
89-92 All Lower Grommet 13-2570-N350

so I have the right upper grommet but I ordered the bolded grommet for the lower

I have a terrible vacuum leak coming from the primary injectors and the air bleeds are in there.

The 84-88 non turbos use a one piece bleed, while 86-88 turbo and all 89-92 use a two piece bleed (Top & Bottom)

so do I need to put S4 air bleeds in there or did I buy the wrong grommet?

help

I would order the cheeper part # as the 13-2570-N326 & 13-2570-N326 is the same part just has a different#..

I have used both part #'s with no problem..

okay I've used both lower injector grommets from both the N326 and N350 and its still leaking, but now I think its leaking from where I plugged the primary oil injectors, do you use loctite or RTV with the threaded plug? I have the banzai block off kit on it currently.

ive tried both and they still leak, I even used some RTV and red thread locker on the OMP plugs and it still leaks!!!! now my LIM to dynamic chamber gasket is ruined and I have to wait till I can I get a new one from the dealer (which they will probably have to order ) to try again. this time I put some RTV around the lower grommets to hope that it wont leak anymore!
