Stuck injector..

long story short I had 3 injectors to do on one truck today, 1,3,4..... 3 and 4 were good... 1 is stuck..... I pulled both rocker arms off/ head bolts, tried pry bars, slide hammers, hammers, chizzles, every an anything to make it move and its not budging.!

the truck was at ford before for heads, half of the oil log bolts were llose, same as the valve covers and ficm bolts, You cantdrill into the injectros I dont know what kind of steel it is but its some tough chit.! Notto mention the injector was "under" torqued I dont knowif the carbon and soot is whats holding it or if the injector welded its self..

Is there any way to get this mother ^&%&%$& out of the head so I can carry on, with out having to pull the head..?

you still have the hold down bolt in, when you remove the hold down bolt, it'll slightly push up on the injector

Yeah, shawn is right. In that pic the injector holder bolt is still tightened down. Not sure what year it is but it's either a T-40 or T-45 torx bit.

You said the hold down bolt was loose so chances are carbon has got up into the seat cup. the injector is ruined so here is what i do on those.
stick a 4 x 3/4 bolt into the top of the injector and weld around it. after it cool"s off, use a long ratchet or cheater pipe and work it back and forth to loosen it. then use a long pry-bar on the bolt head to lift it up. you might find the injector tip out of shape and part of the issue. check the seat cup real good and make sure it"s not scored.

I dont have apic on my lap top but.... on the newer model motors there is a clip on the botom of the hold down bolt that eeps in inplace ( so it wont fall out....) Trust me... that bolt is back out all the way....... I cant get a pry bar under the hold down As you loosen up that bolt is NORMALY pulls up te injector.. It backed out but didnt pull up the injector at all......

No doubt for sure if its stuck like that...that cup is probaly warped......

SOme years when you removethe hold down the bolt comes out........ they made them collared at the bottom so the bolt doesnt come out of the hold down..... If that was the case dont you think I would have pulled out the T-40 and pried up on the hold down?> Il try that weld thing.. Thanks..!! I do have apic of the diffrent hold downs

my cummins did the samething to me... I had to pull the head and DESTROY it to get it out... I WISH there was enough wiggle room to get the hold down out... but theres not... If thats the case I could get my make shift slide hammer in there better to bite on the lip.


How many of you had this problem, I really dont want to pull the cab.....
