You sure the copper washer isn't still down in the bore?

 

ahh.there ya go.even if they test ok (doubtful lol) it sounds like a good set of delphi's are in order.
send a pm here to: typefour
Ford Truck Enthusiasts Forums - View Profile: typefour

and tell him your interested in a matched set of injectors.complete with install kit and Viton O-rings.
(you'll have to ask the price via pm as per forum rules.)

forget that GL ad btw.you could do better here:
http://pensacoladiesel.com/ford-6-9l...injectors.html
if you didnt want them matched.

 

i just got finished with the other side and they were 2BB's and 2E's. looks like somebody put neverseize on 2 of them.

 

so here's what id guess:
all injectors are weak,and spray pattern is god awful.
he likely had a miss,and went to the yard to replace a few injectors.the good ones wore the original pump out,so he scored one from a yard too lol.
so really,you don't know if that ip is worth a lick either.
bummer too cus they are pricey,and since you don't know how well a properly tuned IDI runs,your really not going to know until:
1.new set of injectors.
2.new ip.
3.timing set.

i would guess that if your even contemplating keeping the IDI running like it is now,then it's likely you'd love a freshly tuned one,and perhaps w/a turbo,you'll really like it just fine.
it will never be that PSD engine you have modified though.just know that.but it sure would be much cheaper to maintain too.
it's going to be tough without having a properly tuned IDI to know,but it costs $ to find out.
i guess the thing is though,is you plan on putting it in the current truck no matter what right?
if that's the case,your not going to be out anything to completely tuned it up and see what ya think before deciding swap or not to swap.

your going to need to have her timing checked,after at least the injectors are in:
https://www.ford-trucks.com/forums/9...ing-specs.html
but you'll want to check it again if you install a fresh ip latter too of course.


this is the most powerful (proven) IDI without any internal modifications we have on record currently:
https://www.ford-trucks.com/forums/9...torque-rw.html

so if you know thats just never gunna do it for ya,then perhaps some time and $ is saved.
if you think you can live with that,then welcome to the classic IDI
great engines.im loving mine.worked her good and hard again today.(hauling 2k lb chipper + chips and wood-a whole tree on her back)
with no turbo,she talks to me in 2nd gear on the hills,and with the chipper,and the load she can't maintain the speed limit up the mountains,but i don't mind.

 

if i can get it running good i will consider keeping it in the truck its in now. i had a 92 idi for a couple of years until the tranny died, and it had plenty of power sometimes i think it had more than my powerstroke when it was stock. i pulled the IP to see if the shop iam going to tomorrow can check it out also. i have no problems buying a reman pump IF i know it is the problem. i took a pic of the reman tag on my pump i will up load in a few and see if you guys can tell me about how old the reman is ETC... BTW why did you say to forget the CL injectors?

 

here is the tag, does it mean anything to you? the pump was very clean and I cant see someone who installed mis-matched injectors taking the time to clean it this well.

 

sweet!!
when did the po say he put it in?
how many total miles did you say this rig has now?
is this your first dually? -sorry getting off track,but i wanted to say how niiiiiiicccccccceeeee it is having duals(i just did my conversion.)

looks like your other thread may not get moved.have to show the guys your new rig.

 

the PO rambled a bunch and i usually dont listen because most people selling a used car are lying. he did say that the pump, injectors and glowplugs are new. the injectors look like he found them in the bottom of a river, the glow plugs are nice and shiny, not sure about this pump. i dont know if the 04 on it mean it was re-maned then. i will try and call cat in the am. the truck has 313k, the engine is dated '93. and yes it is my first dually. i was told the engine has 156k on it, once again, i dont belive everything i hear

 

That's pretty...

Make sure those glow plugs are motorcraft/beru!

 

well, if it dont get moved over here, i think we have been posting here enough to be the same. on the coolant issue... rusty water

 

We have a whole forum full of them one section down.

I also have a 97 Stroke that won't catch my 87 6.9 turbo IDI yet.

I will admit after doing the fuel pressure regulator shim, 140 volt IDM mod, 3" down pipe to 4" Diamond Eye straight exhaust and the 6637 mod, the Stroke is getting closer, but still not there yet.

Yes, the 6.9 is "not exactly stock" internally or externally.

The map sensor is most likely for the E4OD computer if that is the transmission you have.
The low vacuum sensor should be on the passenger side inner fender, round about the size of a snuff can with three wires in one harness and one hose attached to it.

You already figured out the tach sensor.

Thge 92 engine in the 97 truck may not fly if you have any sort of emissions checks where you are.
When you install it in the 97 it will have to pass 97 emissions.

That is not likely if you turn the fuel up any at all.

When we turn the IP up, we turn it up one or 1.5 flats at a time.
One flat is one side of the Allen wrench AKA 60 degrees or 90 degrees for 1.5 flats.

One thing that is important, NEVER BOTTOM OUT THE FUEL SCREW.
If you do, there is a decent chance you will hydrolock the IP and schear off the IP drive shaft.

When you turn the fuel up, you are increasing the piston stroke in the IP.
If it builds to much pressure before the IP head opens to one of the injection lines the IP dies an instant death.

Near the cover that looks like home plate on the passenger side of the IP there should be a plate with the IP numbers on it.

In 92 it should have either a DB2-4817 or a DB2-5013.

If it has the DB2-5013 there is a second fuel adjustment.
If you can't see the numbers, does it have a serpentine belt or V belts?

I can also move this post to the IDI forum if you want tons of information since I am having a hard time getting online every day with my work schedule right now.

 

i was looking to get this moved over to the IDI forum, we have been talking over there also. if you want to move it, go ahead, please. i have more info over there in addition to this.

 

ther is a pic of my IP tag in the other forum

 

DB2-4817 is the Stanadyne number, correct for the 92 7.2.

B, BB, C or D injectors will work fine.

The higher letters have more to do with emissions than they do with power.
I would get a set of B injectors if it were me, new is almost the same price as remaned, so just get new ones.

Some of the reman shops do less than perfect work.

 

any big difference betewwn B and BB? i can get a good deal on a set of BB's and the install kit for $200. what do you think about the pump?
