92 3.0 fuel injectors leaking - rebuild help

jburke232 · 11-08-2009, 11:45 PM

I searched but couldnt find the exact answer I was lookin for.

I have a '92 3.0 and the injectors are leaking under the intake. I think I have found all the nice little parts to rebuild and reseal the injectors, but I cant seem to find those 8 little gaskets for the connectors on the fuel pipes. Anyone have any suggestions on where to find them. I was able to locate parts to replace all the upper and lower o-rings and grommets on the injectors themselves along with the 2 gaskets for the EGR and the one for the intake chamber, but I cant find the tiny fuel rail ones.

I need to rebuild and reseal this before I have a ball of smoke and flames. Your help is greatly appreciated.

Now thats a nice site! Too bad there isnt a way to buy the parts at the prices shown, definitely cheaper than the dealership by quite a bit.

Try this on for size: http://www.1sttoyotaparts.com/

Thats where I order my parts from and it saves me money even ordering from Canada and paying extra shipping/tax.

You might consider sending your injectors to witchhunter.com. Bugs tipped me off to him a while back. He charges $19 per injector to pre-test and record the results, then checks the coils, cleans about three times or more if needed and returns them with all new seals, grommets, o-rings, screens and tip guards installed and ready to go back in. Mailing cost about $10 each way, USPS, Priority mail. I mailed mine from MS to WA on 10/22/09 and got them back on 10/30/09.

One other thing to do is pressure test the injector installation for leaks before installing the air chamber, the FSM gives the procedure.

In fact, you could do the pressure test after removing the air chamber to see the leak you now have. Just make sure all the fuel lines are reconnected.

My pre-test showed over 4% difference in flow rate, or whatever its called and my post- test was less than 1%. He sends an excel chart back with the injectors showing those results.

Thanks
Harry

I would love to send them out, but unfortunately I dont have the time to wait for them since my wife andI are now down to 1 vehicle. I did remove the air chamber and jumpped the fuel pump on in the diag port. After doing so I felt bad for driving it as long as I have, the leak is HUGE.

Im gonna order the kit from the guy on ebay and get this fixed myself, especially since I already have 3/4 of it torn apart.

Thanks everyone for the suggestions.

X2 on witchhunter performance. They did a fast turn around for me, even when I was down to one car also. One car is a hassle, but those guys did a great job. worth every penny.
