Exclamation Injector Cup / Sleeve Removal

Has anyone out there replaced the injector cup before? I am attempting this for the first time on my own. Seems relatively simple however I am getting conflicting information about use of sealant on the injector cups. A couple of guys I have talked to have said to use Threadlocker 620. Per the International dealer I spoke with this morning they stated, "no use of any sealant!" This could maybe be why the leak?? What have others done??

Has anyone used the 7.3 Injector Cup Sleeve Puller or Driver from Whitaker Tools? I was curious as how effective the tools were. Whitaker Tools claims to save up to 85% in labor time when using this tool. Are there any reviews of this tool? Thanks!

Would you be willing to sell or rent me the removal and install tool? Also, what were your symptoms that you had that made you decide to replace them, and did it fix your problem.
In my case, I seem to be getting blow by when I remove the oil cap while the engine is running, as well as a miss at low to mid throttle, dealer said it was injector cups. Not sure I agree with that diagnosis.

Umm - no.

Brian - bad injector cups will allow fuel to pass into the coolant. That's it. No way - under any circumstance - would blow by be related to injector cup failure. Can't even conceive of a mechanic that would have the balls to tell a customer that.

All 7.3's have a certain amount of blow by - the high compression of a diesel contributes to that - along with the absence of positive crankcase ventilation (your engine is passively vented through the "doghouse" into your air intake). The quick and dirty test is to put your oil fill cap on the filler upside down. If it has enough blow by to blow it off - its too much - otherwise don't worry about it.

As far as your miss, you need to get a scanner on it to determine the cause. You might need to do a compression test and fuel pressure tests as well.

If you aren't going to do it yourself, you need to find a mechanic that is either more competent or more honest.
