I'm not upset at all just don't like the yeah right attitude. If i'm wrong, just tell me don't be a smarta$$ about it.

As far as the driveway, it you point downhill your motor maybe about level unless its quite steep. I think I'd put the back down then you know its at a slope. Just a thought but you can check it out and see.

 

Ok darin thanks that makes sense, yea i'll probably back it down hill.

 

You call it paranoid, I call it cautious. I don't mind spending a few extra minutes just to be on the safe side. You'll notice I also said I pull the IDM fuse AND unplug the CPS when I pump the motor with the glow plugs out. And if you think I'm paraniod, I know a guy who pulls the injectors, vacuums the cylinders out, then lets the truck sit overnight before proceeding. To each his own.

 

wow, okay, letting it sit overnight, never heard of that, talk about getting every last drop out...

 

so do you pull the idm fuse and unplug the cps before you do anything? and why do you do it? is it so it doesnt trip the computer and start throwing codes?

 

that sounds like a better alternative than hydrolocking a engine, always better safe than sorry lol.

 

It was a first for me too, but it left more time to drink beer.

After turning the motor over by hand a couple of times or vacuum if you don't pull the oil and fuel plugs, or if you do pull the plugs and don't turn it by hand or vacuum, then I use the starter to spin the motor a few revolutions with the glow plugs out (and something covering the glow plug holes). Pulling the IDM and unplugging the CPS makes sure the injectors won't fire and the truck won't start.

It does start to pump oil & fuel back into the rails, so I usually give it a few good cranks with the fuse out and CPS disconnected after I get everything buttoned back up. Then replace the fuse, plug the CPS back in, and fire her up. It will smoke, stink, and run rough. Let it idle a few minutes, then drive it around. When it warms up, get on it for a while. It can take 50 miles or so to work all the air out of the rails.

As for the earlier comment about Jim saying something about not turning the motor over by hand, he may have a point. I'm used to the super duty with an electric fuel pump. Turning my motor over by hand won't do anything for the fuel. Of course I would think turning it over by hand AFTER you stuck the injectors back in but had the glow plugs removed should work fine.

 

Dan, what your doing isn't exactly the safest way actually and He wasn't wrong either.. i will vacuum all my cylinders and won't chance stripping the oil rail plugs, don't gotta mess with the fuel plugs. i can probably vacuum the cylinders faster than you can pull those plugs and wait 10 minutes to let it drain. So if thats your prefered method, then do it that way. There was one thing in there that i saw that i actually do and didn't say anything about it and that was cleaning the oil out of the cups with a rag and i cover the injector o-rings with motor oil to lube them up rather than grease, but grease should be OK and i do put grease on the side of the copper washer that sits against the injector body just to make sure it stays.

Here is what i want you to think about when you aren't vacuuming the cylinders out. by pulling the oil and fuel plugs are you draining the oil and fuel out of the injectors themselves???? Nope, still need to make sure the fluids are all out of the cylinder and this is why i don't see the point in it, but again i say, if thats how you like to do it then awesome, there are others that do it that way too. I just want you to understand that He was NOT incorrect, you were IMO. not trying to be an azz so if i came across that way i appologize ahead of time

 

you can do that or just leave the injectors unplugged all together when you crank it to keep them from firing. i would think leaving them unplugged would be faster since your already there, just plug them in when you put the glow plugs back in.. just sharing that with ya. i actually never thought about unplugging the CPS. LOL

 

Just use Travis way take your time even if it takes you the hole weekend and you will be ok. But like i said once it's back together i turned mine over by hand just to be sure i was not hydrolocked. Better safe then replacing an eng. Not trying to tell you what to do but leave them little drain plugs alone i got a buddy that tryed to pull them and one striped and that was a PITA to fix

 

Ya i know what you mean travis, but I just know that that was the way I did it twice, and this is the way Chris from Jefferson State Diesel does it on all there trucks... And he is probably the smartest guy I know when it comes to diesel's... So maybe I will have him jump in on this tomorrow when i go down to the shop...

 

why? not many of us are going to do it his way??? i for one have never heard of Jefferson Diesel so why am i going to listen to what he says? LoL. i have done quite a few injector swaps and taking my time we can do it in a couple hours on a truck that doesn't have an IC. I'm perfectly happy with my way and will continue to use it esp since i can have the truck started again in a couple hours with a helper? not sure exactly how long it takes us, but if we get on the ball and work it would be pretty damn quick i'm sure. haha.

 

4 HOURS back running for me doing inj. orings

 

If you use comp d you will have heard of them...
But they started there shop about 2 years ago, and now this will be there second year hosting the Redding NHRDA event, they also have one of few towable roller dyno's...
Whatever is safest i guess, good luck

 

haha travis you talk like u have done this injector thing a time or two lol. u planning a trip to oregon any time soon i could use your expertice lol. but darin, chris,fordride and travis have been a great help admist all the heated disussion lol. i will difenatly pull up this thread when doing my injectors and try to soak up all the info on here. and speed might not be the key if it takes me a weekend to do it than so be it, i just want more power, as long as my truck is running haha.

duradan your ideas seem to work if you have done it twice and your truck still works but seems to be pretty contriversal here lol. i too would not want to strip one of those plugs you have been pretty lucky doing it twice and not stripped one.
