hpop question
Good day I have a couple hpop questions. First I had an oil leak from a fitting on the hpop and lost all oil on a trip and then all power of course. The thread was screwed on the pump so we rethreaded and put a new fitting in. Oil was added not sure if he filled hpop res but would not start but after a while it did but running rough is this normal? Any suggestions

Yes, this is normal. When air gets into the high pressure oil system the truck will run rough for awhile, I usually suggest driving 50 miles or so to help purge the air from the oil rails in the head.

Yep, should be fine just give it 50-60 miles to work the air out of the lines. If you find you have leaks again here are some links for you.

If it is puffing white smoke while cranking it is getting fuel in the injectors and the HPOP is probably doing its job. Would lean towards IPR, but wouldn't feel comfortable changing with out some numbers to go off of.

I am guessing you mean the ICP on the drivers side head. If there isn't oil in the connector and it doesn't run better than I wouldn't bother replacing it.

As Clay mentioned, did you unplug the ICP or IPR? The truck won't run with the IPR unplugged if things are working properly, so if yours started, get a new IPR.
