I replaced one of my injectors yesterday, put everything back together and started it up. It fired up nice, sounded strong...but...

I noticed one of the original injectors is leaking from the top were it meets the fuel rail. I was just able to lift the drivers side and swap the injector out. At this point now that I have to pull every part off again, should I just replace all the o-rings and bushing? Or just reseat them?
These are the original bushings and o-rings, they were put into a new engine (not installed by me).

Thanks

I'd replace them all. Also the fuel rail crush washers are one time use items. Read this: http://www.ncttora.com/fsm/1996/SIL/.../inje/inst.pdf

Don't play around with fuel leaks.

BTW it would be a good idea to have the other 5 injectors cleaned, and the whole set of injectors flow tested

 

Where the hell are the fuel rail crush washers and how many are there?

 

The FSM calls them gaskets, there are 4 of them, 1 on each side of both banjo connections. Really they just look like washers, but they are a soft metal that seals as you torque the bolt.

 

Are they the 4 black round things that go between the fuel rail and motor? Guess I'll have to make a list of whats to get at Toyota.

 

No, here are 2 of them. There might be as many as 6, it just depends on how many of the banjo bolts you loosen up.

 

this is some good info....i did not know these were one-time use only..thanks Dale!!!

 

I'm sure there will be someone chime in now and say they have never replaced one and never had a problem. But as long as you are at the part counter anyway and they are cheap.

 

^^

I'd agree. Spend the .75 cents and stay safe. Fuel leaks are nothing to play around with!

 

$0.75 I wish...dealer is killin me for these things.

 

Agreed with replacing the O-rings.

If you can afford the down-time, send the injectors off to be deep-cleaned: http://www.witchhunter.com/

 

i saw this and knew i had too...


i used my old ones and didn't have a problem.

i'm sure goat is plotting my demise now

lol.

 

OK, Just got a call from the dealer to let me know all the o-rings and gromets (insulators) are in:

Here's what I got: (8) O-Rings, (6) Upper Insulators and (6) Lower Insulators.....ready for this...$66 TOTAL!!!!!!

Any place else I can get these?

 

Maybe LC Engineering?

 

 

So after 2 trys (damn over torquing) I finally got the injectors installed. Runs great now. Thanks to this site for all your help. Its alot easier then I thought.

For further preference, I got all my seals (o-rings, gromments, and seals) for 5.00 thats all of them that I needed From NAPA auto

 

i was gunna say try local auto store.
