Are you saying I have a small d#%$ and I can use my condom? Oh, that's true that's why I buy a king of SUV to compensate.

Yes, I follow the direction from one of the you tube to pull the wire from the pass. side and jump to the positive post on the battery.

 

Not casting aspersions on your manhood , just saying anything that holds air. When I typed that I was thinking some people have quite a few around the house. A condom would work fine unless someone has poked a hole in it.

 

Beside the glowplugs tool, what other special tools do I need to buy in preparation for this injector work?
I saw that I need a long torx ~6" long, what other tools to take the injectors out?

Thanks,

 

I use a 4" T40? for the #5 and 7 injectors because of the HVAC box. 6" might get you a little crooked on the hold down bolt.

On the glow plug harness I've found that it helps to give them a very slight back and forth twisting motion as you start to pull them. Be as gentle as you can because they are way too fragile. You might even want to invest in the side that you are pulling but IMHO it's cheaper to buy 4 injector O-ring kits than one glow plug harness. The leaking injector will be very apparent.

 

I would recommend replacing all 4 injectors on the bank that has the failed injector. The reason being that the injectors really don't like air, and they share oil and fuel on each bank.

 

That mean after I find out which side has the bad injector, go ahead and order 4 injectors and replace. No need to figure out which injector(s) by doing the glow plugs test?

 

That's what he's saying.....

 

Yeah, I learned the hard way after replacing one or two injectors, and then having to go back in to replace the remaining two or three injectors. After doing that a couple of times, I started doing all 4 on the offending bank. These injectors really don't like air.

 

In your experience, how long does the other bank last after you changed one side? I hate to go in again in a few months or days to change the remaining 4 injectors on the other side.

 

the other bank should not be effected by replacing injectors on the opposite side. the fuel lines T off at the filter housing and dead ends in the head. there were some people back in the day installing a braided steel cross over line in the back of the heads (there are plugs back there where the banjo bolts would be on the other side of the head) but this mod doesn't seem to have taken off like others have, so i can't really see how any air is going to be able to make it to the other side of the motor. having the fuel lines off for the bubble test might introduce some air, however doing an oil change will cause no oil pressure for 1 or 2 seconds too...what can you do about?!?! i don't think swapping out injectors would cause enough damage to the others to worry about it. personally i would try to isolate the culprit injector and just replace the ones that are faulty (there's no telling if, when, why your injectors might start to fly south...so you might be ahead of the game by replacing all of them, or you could be replacing them when they still have 100,000 more to go...you just don't know). i guess its all what you want to do, how often you want to be wrenching on your truck, and if you have the scratch to throw at it just cause your in there.

 

The other side should be fine. There is really no way to predict injector failure. I have replaced them in trucks with less than 30k miles, and I have seen trucks with over 100k and all original injectors.

 

Understood! But my Excursion is currently at 155K miles, bought it at 125K miles in December 2011 (about two yrs). Like to have a feel on an average, how long does the injector last from all 6.0 owner.
