My experience is that bubbling is often the prechamber (washer/seating problems just leak). Replace or clean and reseat the washer and retorque the injector. If you're still bubbling it's the prechamber.

Just did this recently. The pre-chambers have a seal ring on them and are held in place by a screw collar. Two special tools are required for this job- a wrench to remove the slotted screw collar and a puller with the proper threads to screw into the pre-chamber. A slide hammer is usually used with this tool as the pre-chambers get "locked" into place from exhaust residue. They can require several heavy slams of a slide hammer to pull/remove. The pulling adapter costs about $40(without the slide hammer) and the wrench is $75ish. I think there is a thread on here that had a solution for the threaded adapter (?) But the wrench is almost a must have as the collars are torqued at up to 130ft. # ,and if a little rusty ,can be very difficult to remove.
Remove the parts.(glow plugs must come out first) Clean things up. (use a shop vac with a small hose duct taped on the end to vac out the cylinders)Replace chamber seal rings and injector seals(I use liberal amounts of anti-seize compound on the screw collar threads) sweat the details, and that should do it.
