Your available resources deoends on how much you can or want to spend. You can order a remanned 4.0 OHV from a parts store with a warrenty for close to two grand. It will need valve covers, alternator, water pump, etc., but it has the heads and valves.

You can get a used engine from a salvage yard (or other places) much cheaper, but often without the warrenty. It also depends on if you're doing it yourself.

Personally, if I couldn't find an engine that I knew was in good shape, I would go the remanned route. Because having to do a job like that twice for no reason other than being cheap doesn't save you anything.

I agree, I would need to know the motor is good. I disagree, however, that salvage and junk yards are hit or miss. A strong majority near me offer very good warranties. You can't always tell overall wear on an engine, but with modern gas engines running 300k miles easy, I wouldn't even worry about it. You can tell pretty easy if a motor is bad when looking it over. I would pull the oil pan an inspect the bottom end good. Its a good idea to replace the oil pan gasket anyway. I would also compression test the motor. If the oil was full and looked good when I got it, no obvious signs in the bottom end, and it had good compression, I would not hesitate to put it in a vehicle.

I have to agree and the oil pan gasket is a smart move since they can leak badly and are not easy to replace with the engine in the truck.

I have gotten a warranty from a junk yard, but there's some I've been to that don't, which was my only point. They are a good option if they have a good deal. I saw one at a yard that made me double take! Looked very well loved. I asked about it, transfer case failed, everything else was good. Now, I'd have taken that engine in a heartbeat. Maybe the whole thing if my situation allowed.

KF6NFW, just for my information, why are you considering replacing the engine? Is it beyond a relatively simple (i.e. top end) rebuild? When either of my DD Ex's engines go away, unless it's a lower end issue I plan to either rebuild it myself or have a local shop (which I consider the best I've ever encountered) do it, depending mostly on my time and $$$ situation.
