This is what my uncle used to do with junkyard engines for his I/O. He'd pull all the plugs and change the oil a couple times-- first after cranking over by hand and then after running the engine on a pallet for a few minutes. He'd get 2-3 seasons out of a boneyard buick engine then go get another one for $75. I think he had more time than money.
