    Yes they just slid off but OEM ones are pretty hard to slid off. I just cut them.

    Old seals can get rock hard and be difficult to remove. If you do decide to cut them off be careful not to damage the injector. The seals fit over a groove in the injector to hold them in place. When the seals get rock hard they shrink and allow a lot of air to leak. The injector and seal should be a snug fit into the sleeve. That way you know it won't leak. The clip is important. In the event of a backfire it prevents the injector from popping out.

    Thanks guys, I ended up not needed them after all (I had spares and din't realize it.)

    My VIN:    4519

    First start in almost 15 years...

    4519 is running!


    Everything I worked on (to get it running) was fuel-related:

    -Cleaned the tank & lines
    -New fuel pump & fuel filter
    -Swapped the RPM relay, fuel distributor (w/lines & WUR attached) with Jimmy's parts off 2706.



    The engine sounds really good; the valvetrain is quiet and the motor sounds "tight." It "hunted" a bit for a few minutes, then had a steady idle.

    I think it could have a leaking head gasket (there's a lot of heavy white exhaust.) I also think I caused a vacuum leak somewhere; it was idling around 900 with the air cleaner off, but slowed down when I covered the hose to the oil fill. When I put the air cleaner on, I think I wrestled a line off somewhere....RPM's went to ~1100 and stayed there with/without the air cleaner.

    Another DMC rises like the phoenix!

    I presume when it was running it was bone chillingly cold in your garage; hopefully all of the exhaust you saw was just decades worth of moisture burning off rather than a head gasket leak. Fingers crossed...

    Good point, it was in the teens. Tonight I ran it and think you're right....might just be the cold weather. I didn't smell coolant in the exhaust, so I'm remaining optimistic!
