Check your intake heater injectors!

[texas30cal]

Mine started dripping fuel yesterday around the plug at the rear, I thought about eliminating it but decided to see if I could fix it. I pulled it and found that it's just a o-ring that seals a aluminum plug in the rear of it. I'm sure glad I decided to fix it because I found the tip of the injector was loose and already 3-4 turns out!!!

Yes, they are known for causing issues. I've eliminated mine, so being in Tx, I doubt you'd ever need it.

Check posts #2 and #44 if you decide to eliminate it.

Are they known to fall out into the turbo? I'll check it out thanks!

Not that I know of, but I'm learning new stuff every day! In fact, I learned a Dodge pickup front caliper can "just fall off" when your driving through a construction zone and can't pull over for 30min, just this summer.

Great tip! That is something I forget to check during my maintenance. I need to check out my injector....I live up here in the TX panhandle so I actually use it during winter.

I couldn't get my injector apart to change the o-ring without totally destroying it, so I rerouted the fuel supply lines and capped the injector. Then put it back in it's place. No more fuel leaking on the turbo anymore! I still inspect it to make sure though. (Pre-Trip-Post-Trip).

Remove it and make sure that brass tip is tight, mine wasn't far from falling out and into the turbo, the o-ring that leaks is on a plug under a snap ring, remove snap ring, cover plug with your hand and a rag and blow it out with compressed air. I'm not sure of the o-ring size bc it was in a box of random ones I have.

Removed the injector to check the brass tip, it wasn't loose, but it wasn't all that tight either. So I tightened down. I couldn't get the plug with the o-ring apart. (2nd attempt). I put it all back together with a new snap ring.At the very least, it doesn't leak fuel down on the turbo.

Well at least you know it won't fall out

I capped mine off the following way --

Both of the lines and then the two fittings that the lines went into were removed from the injector body.
Both of the fittings were sealed with brass caps from the home despot place. They are both the same size.
The size of the caps is 1/8" FIP
Then the lines were put back into their own fittings. I moved them where it would be easier to check for leaks.
I used teflon tape on the cap end threads and also I wrapped the injector to minimize dirt entry.

This is not a permanent fix but now I can drive it without fear of a fire, from this cause, anyway.

Yeah that too!
