im a f'n newb when it comes to diesels alright, now that we got that out of the way, im going to go look at a diesel jimmy this week for $600. originally i was planning on just swapping the 6.2 into my other k5, but im not sure yet. anyway, engine wise, what do i need to look for, check for when i pop the hood on a 6.2? what bout smoke from exhust etc? thanks a bunch.
