my 93 4.0L I6 has about 213k miles on it. the tranny has about 75k, i put a new radiator and water pump and belt on it not too long ago, and a new alternator. my question is, what else should be done to it to keep it running good for another 10k? are these easy spark plug changing type things, or do i need to do an engine overhaul? i dont want to get rid of my baby, but if she's getting to the point where theres just too many miles on her, i guess i might have to. please help
