    Default D2 no start .... now started with blown head gasket

    D2 3J was parked for a year (inside). Always fire right up, especially in summer, with electric start. Long story shorter :
    Would only fire with a shot of juice. Drained fuel ( was stinky - not normal smell) went through the bleed sequence and got her going. ( real time about 4 hours : (

    Right away I noticed gray / white smoke and it never cleared up. Cylinder balance ( crack injector lines) shows #1 is dead.
    Radiator is bubbling. Seems I have a head gasket leak now ?

    I know ďanythingĒ is possible ... but ever heard of head gasket going bad while sitting ? - jest kewr-e-us...

    Seems to be more common than gasket AND a lot easier to check out and fix. I would start there.
    D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time

    If the seats in the head are not real smooth, I have had trouble sealing the washers. i believe the old time ones where copper. All the modern ones seem to be steel with copper paint. Engine rebuilder found real copper ones at McMaster-Carr. They sealed and ended my problems in that engine. Have another I just don't seem to get to.

    Doh Bummer Jack!

    That is a real rain on your parade moment Jack!
    Yes, sounds like bad precup or head gasket issue.
    Youíre pretty savvy, so Iím sure youíll get the little D2 back to 💯 soon.
    Havenít heard from you in quite some time. Always wondered what became of you and your D2.
    Maybe life was quieter without all of the extra iron you had? Please let us know how things progress. JM

    Thanks all, and JM. We had a fire here ( near keene, CA) and it got within 15 ft of my building where little D2 was sleeping. I pulled him out with a chain, and after fire was out - thatís when my new problem began. ( down hill out of building - uphill into..)

    SO I have been reading and I guess the copper ( or soft metal) seal could allow combustion in to the cylinder ? I will pulli injector and Then prechamber ( if Iím lucky from what I have read). If that seems good then the head comes of next.

    Thank all

    Copper gaskets if not mangled can be annealed and reused. Bob

    Most likely a corrosion hole in the pre chamber.
