What will fit my 88 d50
I was given a 1988 Dodge D50 4cyl 2wd auto by a friend for my birthday. The truck is mint (for Maine) with the exception of the engine. It ran and drove when parked (12 years ago) but has sat and now will not turn over. I have filled and filled it with marvel mystery oil but it's draining somewhere and not sure where to. I'd rather not have to tear down and rebuild the engine.(don't got that kinda time). I was woundering if there is an engine that would derectualy fit the auto trans that's in it? And if so what else was it in.. looking for the cheapest and easiest engine to slap in and get this moving.
