    You guys need a solid block of hardwood about the same diameter as the piston. Place it end on on the piston and hit the top of the wood with a sledgehammer. Works every time!

    Looking forward to more! Thank you for the extra explanation. Great video.

    Good progress. I’ve done one D4 with a tight engine years ago and have another early one waiting. I cleaned the liners up with sunken hone, new rings, reused head gasket. I used conventional o-rings one liners. They were too narrow for groove so I filled void with silicon and let cure before a fresh film of silicone on o-ring just before installing. The liners will do just fine with some fine pitting. I’m kind of cheap or frugal, what ever you want to call it. All I bought were the piston rings and liner o- rings. Everything worked out and it runs good. I’m going to subscribe and keep watching.

      The acetone works on any rust and transmission oil penetrates and lubes

    It still might have a stuck Cam Follower, as it seemed to stop the rotation fairly quickly. I missed the bit where you needed to park it on a hill top...!

    • @John_Graff
      @John_Graff  Před rokem

      We started a teardown of the engine. Video on that will be out tomorrow. It was parked on the pile of stone because that's how it got unloaded. They delivered on a flat bed trailer with no ramps.

    It is surprising how well beer can save the day if the clearance is too loose.
    Dont recommend it and you have to make sure everything is not way out of round and journal is clear.

    This one will need a lot of work ! When using the log and sledge hammer on a piston , Be careful that the engine doesn't start on you ! Ha Ha

    Try a torpedo heater to heat that engine up to a summer temperature to help the the oil to creap where it needs to go.
