Got My Injectors:
 
Got My Injectors, stage 1's from Rosewood, sent them on the 15th PM and got them back on the 27th AM, that's 12 days total turnaround time (USPS) Spoknae WA to C******, Ohio. Great service, thanks Jim.
Now all I have to do is install them, and hope it solves my shaking engine problem, Jim had to replace one injector due to inadequate oil flow.
If anyone has any good tips on the install please feel free to offer any advice, never done this before and sure don't want to screw it up now. Especially interested in methods of removing oil from cylinders and procedure for refilling oil. I'll appreciate any advice I can get.

DZL JIM 10-29-2010 06:14 AM

If you have a small vac pump, hook it to a piece of 5/16" brake line and stick it in the injector hole and suck out the top of the piston.
If not, install the new injectors and remove all yoru glow plugs. Make sure injectors are fully installed and bolted down, bolt the valve covers down and crank the engine over. This will purge fuel and oil from the cylinders thru the gp hole.

To install the injectors, oil the o-rings really well, amke sure copper washer is properly fixed to the nozzle and stick it in the bore. Beat it into place with a mallet or deadblow. You can beat on the top all you want just stay away from the solenoid clip or you could easily break that off. If you can't get a good swing at it use a screwdriver and beat on the hold-down strap, or use a dowel (piece of broomstick) and hit against the solenoid somewhere. You need to set them good by hand, till you hear the distinct CLINK of metal to metal.
Then torque the hold-down bolt to 120 inch pounds.
Don't guess at this, it needs to be correct. Too much and it will squeeze the washer too flat and not make a good seal.
Not enough torque and you won't crush the washer enough and the injector will essentially loosen up and cause lots of problems.
You can NOT seat the injector correctly by drawing it down with the bolt, you have to seat it by hand first.

Hope this helps.
Jim

What Jim said. I did mine a few months ago.

Oil the 0-rings really good, tighten everything the way it should be, and if you do pull the glowplugs out to purge it I recommend pulling all 8 just to be sure you get all the oil out. And make sure the valve covers are bolted down at least at each corner, that oil shoots FAR! (don't ask, the side of my house repels water really good now).

And if you have a battery charger charge up your batteries really good before you start cranking because it will take a while to get it to fire up.

Talyn 10-29-2010 10:08 AM

Double check your torques downs after you have them all torqued in.

MagKarl 10-29-2010 10:09 AM

I like to dunk mine in oil to help assure no o-ring pinching or twisting on install.

Pull the glow plugs and roll the motor to purge the cylinders. I do it by hand the first two revolutions, you will be amazed how far the oil/fuel mix will squirt even when turned by hand. Then put the covers on and spin it with the starter to blow out the rest.

Top off the HPOP. Replace the HPOP plug. Then crank for 10-15 seconds. Crack one of the head plugs to purge the air, re-tighten. I'm talking about the big hex plugs on the top of the heads. Then repeat on both sides till no more air comes out and the HPOP stays full. It should start very easily now.

I think it's a good idea to change your oil if you are burping the cylinders and letting it run into the pan.

JamesHajek 10-29-2010 07:24 PM

So for my own understanding, if you have a vacuum, you can just suck out the cylinders and not have to pull the glow plugs and bump it over? or If you suck the cylinders, you still pull the glow plugs?

427 fordman 10-29-2010 07:34 PM

You can just suck the cylinders, that's what I did, just make sure they are clean. I used a syringe (spelled right?) and a small plastic tube on the end stuck in the injector hole.

DZL JIM 10-30-2010 07:05 AM

I have a 12v vac pump with a piece of brake line and I just suck them out.
If you remove the back 2 injectors first and let everything drain into them, then you only have 2 cylinders to clean.
I've always used the vac method and have never had a problem.
There will be a small amount left in there and just bump the motor over slowly till it spins freely and there will be a bit of smoke on start-up, but it has always worked for me.

driximus 10-30-2010 09:35 AM

I used a hand pump for putting the Oil in the Axles and transfercases. its just a basic push up and down pump that has a Long tube on both ends.

Talyn 10-30-2010 12:52 PM

With no vacuum pump, i used the pull the relay/fuse method with the GP's out and the VC's on.
my god if you do it this way put the vc's on with a bolt or 2, just sit them on there.
I tried to do jims method, but had problems with number 7.

I turned my engine over 2 or 3 times pulling the VC's and cleaning them to check for oil, got oil every time.

Just trying to get a majority of it out to prevent hydrolock. I believe the rest will make it past the rings or out the valves.

out of all the important things to do, its just making sure the motor is free of oil.

lube them injectors up good before putting them in. Some dunk, some stroke.

Use a dead blow hammer to seat them into the cup.
be sure not to hit the solenoid plug when doing it. You'll hear a very distinct ting or ping sound when they are seated. So turn off the radio and listen close.
Then torque them down and double check your injectors a few mins later on the torque again.

richdawg 10-30-2010 02:15 PM

Thanks for all the feedback guys, I'm going out now (it's noon) to suck the fuel out through the GP holes, going to be using the syringe method, I'll let ya know how it goes. The temperature is just above 40 and not expected to get much warmer, so got to get this done soon, snow is a coming its just around the corner for us.

richdawg 11-02-2010 01:47 AM

Well, I finally got it all done, but I am not happy with the results, when I first fired it up it smoked and shook pretty bad about like I expected. So if figured it just needed a good run, don't know about smoke it was dark. I drove it about 30 miles tonight, the shaking never went away, not at all what I expected. The stage 1 injectors seem to give a little more power than I had before. :confused: Don't know what to do now.

Brown Falcon 11-02-2010 05:33 AM

One might not be seated correctly, or might have knicked an o-ring?

MagKarl 11-02-2010 09:59 AM

You won't get much power increase with stage 1's until you get a custom chip burned for them. Any improvement you get is likely due to the overhaul of your old injectors, they won't deliver any more fuel than stock until a chip tells them to.

My buddy put stage 1's in his truck and is putting down 300 without a chip??

Also, Richdawg, dont know how many miles you drove, but ive heard it can take up to 100 to get the air out of the system.

JamesHajek 11-06-2010 01:19 PM

Just checkin up on this thread... I am going to be swapping my injectors tonight and there is some good info here. Richdawg, is there anything i should be looking out for?

richdawg 11-06-2010 01:51 PM

James, I just got kind of burned out doing my swap, a little to much stressing about doing something wrong (like not draining oil properly causing hydro- lock) which can bend a rod. I haven't made any progress with finding the problem miss I was trying to fix with injector change. I a little slow cause I'm a lot older than most on this site and its just a lot harder to absorb this diesel stuff. I am still learning and fore the most part enjoying learn what I can. James feel free to PM me and I'll give you my phone number if I can help you with anything. Going to be away from puter for most of the day, but I'll have my phone.

Brown Falcon 11-06-2010 02:04 PM

Hey james, if you need any help feel free to send me a PM too. I had mine out and re-installed 3 times within the last 6 months (long story).

I'd be glad to help you if you need it. If it's easier on the phone just PM me your number and I'll get back to you asap.

JamesHajek 11-16-2010 03:25 PM

Richdawg, you ever get your truck running where you want it?

superduty4x4 11-16-2010 04:27 PM

richdawg if you need to get that truck hooked up to AutoEnginuity let me know, I'm in Spokane more than I care to admit. There is another member that might be willing to hook it up for you too out in Cheney.

oldbird1965 11-16-2010 11:11 PM

Ya, I hope you got it fixed Rich and your in Parker, AZ soaking up the sun.

richdawg 12-03-2010 12:39 AM

Thanks for asking, I had to give up do to health issue and weather. Record breaking snowfall for November, ever.

oldbird1965 12-03-2010 12:43 AM

You should be in Parker!

Thanks for the offer on AE hookup, just to cold for me right now and I don't have a large enough garage to work on it in. I started it yesterday after it setting for about three weeks , it surprised me and started right up. More white smoke than usual though, till it warmed up a little. Engine still has the shakes though and smooths out a little as RPM's increase.

Glenn, I would really love to be in Parker and at the Riverland Resort in Earp CA. where we stayed last year. We had reservations for this year but had to move them over to next year. Hopefully I'll have my truck fixed by then.

Gagew90 12-03-2010 01:15 AM

along with what everyone else said, unplug the cps when purging oil with the gp's out, very unlikely the truck will start so soon when your just purging but better to be safe

Well the offer stands if you ever want to do it. If I could get some crap cleaned out of my garage we could roll it in there and throw some wood in the fireplace and have at it, but my garage is a disaster zone right now.

richdawg 12-03-2010 01:14 PM

superduty4x4,
Thanks again for the offer, maybe we can find some time after the holidays & I do really appreciate your interest and follow up on my problem. I don't really know what else to do, don't want to just throw parts at it, can't afford that. AE sounds like it could be the answer. I have thought about buying one but not sure how user friendly they are.

Sounds good, just give me a shout!
On second thought, there is another member that lives in Cheney (Pwerstroke99) that may be able to hook your truck up and scan it for you.

rideracelivemx7 12-03-2010 02:46 PM

its not the injectors if it went to jim, he bench tests them to make sure there 100% before they are shipped back, no BS from jim ill tell you that. you might have a burnt valve cover harness if it has a miss.
