    Popped the hood this afternoon and noticed this plug was kinda greasy. Truck ran fine but just noticed it. IMG_4127.jpeg Took a little brake clean and sprayed it somewhat clean, after the engine had cooled. What exactly is the name for this piece going into the head, part number and best way to remedy what I’m seeing.

    The pic is from after I sprayed it with brake clean and it kinda appears that oil may be leaking from the plug receptacle.

    Best way to remedy the problem is pull the boat anchor out and sell it for scrap iron price .

    That's called an injector pass thru.
    I would change all of them. They aren't too expensive, just a few bucks.
    Register on Cummins website.
    Quickserve. Lot of information there

    There is an o-ring on those pass though connectors , if you pull them might as well replace the connector, they have been known to go bad.

    By chance, is the part number the same for a Celect and Celect +?

    Was"'t wait'n on you ... Just reassuring everyone my.opinion about Cummins boat anchors has not changed ..
    Nor the fact that those motors have a history of having issuses with the injector harness & the pass throughs
    But you rest assured they are very reliable about being unreliable

    I’ve got a few Cats, Cummins, a Detroit, Deere, IH, air cooled Deutz and it seems I’ve had good days and days I’ve spent wrenching on them all. I do like the B model Cats though.
