Oil above the sealing washer is a leak in the sealing washer or the injector body.
Hummm. Hat does bring up a question I?ve had in general: What is lugging for this engine? I generally try to drive gently, but I?m often at 2000 rpm when starting off in any new gear. I usually let the turbo come up and the RPMs to come up to about 2200 before asking it to accelerate.
I have to say, despite all of my crap I keep throwing at you guys, this thing does run well. I wonder what would happen if I never looked under the rock and just drove it.
Just conferenced with our diesel engine trainer on this.
He said it looks like there is a fuel leak from the injector body. So at this point, I'd say the injector needs to be rebuilt/replaced. And as always, if you do one injector, you probably should be doing all four.
Didn't he indicate the injectors have less than 5k miles on them since new/rebuilt and that swapping in a cleaned and recently tested injector results in the same diesel ping noise ?
fact is if you cant breach 1k you are way under fueled.
