Unsticking an unused engine........

Miranthis said
Thanks for the suggestions. I suppose I should add that none of the spark plugs were rusty at all when I pulled them, so i hope that means the rust is just the usual stuck rings and surface rust in the unsealed portions of the engine. I will be rebuilding this one, but will keep trying at this point to unstick it as having it running, even a little, will make loading/unloading etc. so much easier. Will pull a valve cover to get an idea of the inside engine rust.

diesel engine OIL or diesel fuel?

I was told to be sure its "USED diesel engine oil". Cannot speak to the science however it was explained to me that the chemistry changes as diesel is used inside an engine. That chemistry change enables it to eat at rust and lubricate somehow. All I can attest to is that it worked twice for me. Both in 1947 engines that sat for well over 30 and 10 years. Never dismantled the engine at all other than the fuel system and cleaned the carb.
