    Think this cylinder has low compression?

    I had this gut feeling the sound of pieces dropping into the oil pan was what was left of a piston.

    when the pic was loading (yes im on dialup :p:) it looked like there was a stream running out from the cyl wall next to the hole. I was going to say I found your problem someone left the cyl cooler switch open... but then I saw it was really a ring! :yikes: How'd you blow that piston up?

    I was told this motor was "bad". When I got the truck home, I went to try and start it to see how bad. It fired once. Then fired a 2nd time (priming it with gas). Then it pulled fuel up, fired and ran for a bit once it pulled up fuel. It was making a not so loud clatter. Then all of a sudden, after about 10 seconds of running, it sounded like a big backfire, and it died. Wouldn't spin over anymore.

    I drained the oil... and 2 gallons of coolant came out before oil (there wasn't any water on the dipstick when I first tried starting the motor).

    I'm thinking a wristpin was the initial culprit. Then when I fired it trying to make it run it must have shattered then.

    To the right person, it would still be worth having the one cylinder sleeved. The rest of the cylinders are all standard and the crank is standard.

    "right persons" hard to find lately--

    Its not easy to find someone willing to buy an engine that needs a sleeve,unless its a rare block or they want matching #'s ,but you never know.....but the bright side is.........

    Scrap is 75 bucks or more a ton here,might be more in your area--that motor will still buy your groceries for a few days,even it its current state of disrepair....:grin:

    NICE!

    Reminds me of a story that a guy I work with told us. He was an armored-vehicle mechanic with 1st Armored Division in Iraq; they had a bridge-launcher take a hit and come in (under it's own power) for repair. The bridge launcher is powered by an air-cooled 12-cylinder Continental diesel, and each cylinder has it's own "jug". Well, whatever hit them took out an entire jug, right where the jug bolts to the crankcase.
    The motor still ran!
    He said it sounded like s**t, but it ran. Said it was insane to stand there and watch the crank throw for that jug spinning in a no-BS running diesel engine.....

    2 stroke conversion>:saweet:

    Or did you get tired of water cooled and switch to air? lol.

    What ever happened to the old two stroke diesels?
