Yes those are the injector hold downs

Don't forget blue locktite on the balancer bolts, and your turbo is likely shot

Hello fellow diesel enthusiasts,

So I just picked up an 05 Limited CRD that has a cracked cylinder head. The P.O. had a dealership take it all apart but the tech did not label any of the parts nor put it back together! The cylinder head has been verified that its cracked just under the valve seats on cylinders 1&2.

So now its in my garage and I have laid out all the parts on the floor and started to clean them up while I wait for a new head from VM and parts from IDparts. I think I pretty much know where everything is supposed to go with the exception of this one part. I have the FSM and I can't find any reference to it. I'll posted a pic and hope it comes through but its about 3.5" long steel tube with threads at both ends. At one end, inside it accepts a very large Allen key that it would seem that it screws into something. It was covered in oil/carbon//soot.


Does anyone have an idea what this is and where does it go, assuming it is actually goes with this engine?

Thanks for any help you guys can provide. I already own an 05 3.7L Limited and used this place to help rebuild that one with the vast knowledge of you guys on here.

If one of the treaded end is M21, it might be part of an injector puller !

That is NOT an injector puller part - at least not for this engine. The injectors can't come out with being side-loaded (where the hard line connects) and the Miller tool - if the dealer monkeys even had that - doesn't use that part anywhere either.

Not sure what that is or where it came from, but it wasn't from the CRD.

When the head arrives from the UK, take it to a machine shop and have them pressure test it. Then replace all the valves in it with brand new from IDparts. The VM Specialist is a "breaker" or boneyard over there, and they have said to several of my customers that they were "replacing all the valves" before sending a head.... And what arrived had valves that were NOWHERE CLOSE TO NEW. They had been cleaned, sure.... But cracked at the bases, covered in hard deposits, and obviously worn. I trust that they have parts that will fit. But not anything beyond that, b/c they have been claiming this "test engine" nonsense for at least 4 years now. I don't think there's that many test engines to be had, but this engine IS used in the black cabs and in minivans over there, so there are LOTS of used engines running around to pull from. Caveat Emptor.

You will be fine, they aren't going to spend the energy to do anything other than hot tank the heads - and that's OK. The cost of replacing the valves is just the cost in parts, about $300, and then you will KNOW that it has new valves. You don't need to do anything with the seats, springs, keepers, or guides as in most cases those are all just fine. Just lap the valves in with compound, clean, and you will be good to go.

Sounds good. I'm at a point now that I'm just waiting on parts to arrive in the mail. Cleaned up the valve/cam cover and since the jeep already has a SEGR it didn't have that much soot/carbon build up. In addition, I physically removed the EGR and all of its coolant plumbing and made some block off caps to go on the exhaust manifold and FCV.

Don't forget to remove the butterfly out of the FCV.
