I ran across a old trencher with an air cooled deultz 4cyl engine. This thing has been sitting for a few years. I am wanting the engine for a project, but when I pulled the dipstick, it had a lot of grayish sludge on it. Since the engine is aircooled, I suspect the moisture is condensation, or possibly rain water that has somehow gotten into the engine. It would be a lot of work to pull this engine and just wondering if it would even be worth the effort. Its a 64hp motor and if i can get it to run would make a good hydraulic pump puller. I'll know today once I get the backhoe attachment off if the engine is locked down, which if it is, I aint going to fool with it. If it isnt locked down, I am just wondering how much possible internal damage there could be since the engine oil does show signs of moisture. I should note, the gray sludge isnt at the top level mark of the dipstick, but only on the bottem end so the crankcase isnt completely full of water. Has anybody ever rebuilt one of the aircooled dueltz engines and what kind of cost should I expect if i decide to do a teardown and rebuild. I will only be paying scrap prices for the engine and it is complete except for a battery.
