Injectors stuck....cannot remove?

This may not be my issue...but I've read about if the copper washers double up because of people forgetting.  Maybe they were replaced at some point.  What would be the effects of that situation?

 

 

 

Most likely would never get the injector in or lined up being it would stand up so much taller and the crossover tube won't line up right and spray pattern would be most likely wrong. I know there is a wide range of copper shims but I really doubt you could get 2 stacked and get a injector lined up in the hole.

I could rotate them as I said but they would not go up.

 

Anyways the copper shim crush to the injector not the head. So the injector will still lift out. The o-ring is the only thing that would hang it up. So if the o-ring burnt to the head is will stick and hang up. All I've ever done is screw that short intake bolt in the head and then using that flat blade screwdriver and pry them out.  I've even use small nail bars before.

Pull the tubes and retainers then crank the engine over. You might end up with 6 holes in your hood but I guarantee they'll come out really fast.

Whatever it takes!  I read about something similar on a 12 valve...made me giggle

You might try what @JAG1 suggested with a piece of PVC pipe, a washer and use one of the short bolt from the intake horn. Crank it down and see if it pops loose. That or pry harder like @Mopar1973Man is saying. Just kind of perplexing to me they wont budge, just no that much holding them in place. The o ring lives with oil on side and fuel on the other.

Nothing like popping injectors and getting a redneck compression test at same time. Make sure all neighbors are indoors.

 

Possible those O rings turn into hard rubber over time. I would soak a bit of oil down around ea. one for an hour or so.

Ummm... The injectors are swimming in engine oil... Then the other side of the o-ring has diesel fuel.

 

My crazy idea of getting them out...

Like Mike says they swim in oil every day of their lives with diesel on the other side of the o ring.

Not sure I used a claw the first time i did mine but as easy as the popped out I could have. Was not sure what to expect the first time.

 

@sooxies How far would those injectors rotate any way?

360 degrees....in slow increments.  Kind of like a chopping motion..not a fluid movement.  I like the idea of using a hammer for leverage....that would be worth a shot.  But the number 5 fuel line is still another issue.  I soaked it in PB blaster overnight and it still wouldn't move.

Might need a high quality crows foot, pipe wrench style to get that #5 loose. Use plenty of PB blaster on it. Might have to shock the fitting to get it moving so look for that crows foot for that purpose and might try rattling a impact against it a little bit.

[Thunder2001]

A slide hammer would get em out for sure. At least it would not put a sideways force on them. And just go easy with it.

1 thru 4 maybe but 5 and 6 would be a challenge. Not sure Snap On sells a tool for that.

Would something like this work?  Put nut on all thread bolt,  place bolt with nut through large fender washer, place short peace of pipe over injector then put bolt with nut and washer into the injector.   Now tighten the nut against the fender washer while counter holding the bolt head.  This should 'suck' the injector out.  You may have to take the valve rocker arms off but at this stage of the game what else can you do. 

[dripley]

Thats petty much what the fancy tool does and what @JAG1 suggested with pvc pipe. Should work just fine. 

[JAG1]

'Mopie' (Michael Nelson) gets the credit cause he first told me about the pipe trick. And IBM adapted it to work on the 24 valve style.

I bought the tool from Tork-Tek....I'll report back when it warms up again in the garage.  Give it another go.

[crf450ish]

won't the use of a slide hammer to remove the injector, damage the injector?

[dripley]

While it would not be my first tool of choice. I cant see what harm it would do. They just pull straight out and are not attached to anything.

[JAG1]

Let us know why they were tough to pull.

Got the job done; the tool took them out with no issues.  P.O. had 275's in it which is what I just put in...no worries.  But now I have a leak from what I think is the return line on the back of the head?  It's not the number six line I know that.  It's dripping down to the bottom of the bell housing.  My rear main is shot but it is for sure fuel.  I never touched the return line nor has it ever leaked so I'm not sure why it's leaking now.  I do know it's common.   

 

Between doing a valve adjustment and these new injectors it idles a lot quieter and smoother.  I do notice however, it chatters a little different.  Kind of hard to explain without hearing it in person...it's very very minute but I have sensitive ears.  Not sure if that leak in the back would cause it.  I would only say that because of when you bleed the engine and it idles like trash until the lines are tightened down...and air is out of the system.  Truck has the power...no loss whatsoever.    

 

Fixed one issue but created another.  I like solving problems so I'm not that frustrated.  Luckily I walk to work. 

 

Cheers fellas for all of the help.  Really means a lot.
