Engine Compatibility
A question that highlights my laziness:
I have a ‘93 F250, 4x4, 5.8, E4OD. The engine is old and tired, compression varies from 70 - 110, oil pressure is low. The truck runs very well, trans shifts crisply, suspension is very good.
I would like to buy a low miles boneyard motor and drop it in. One day in and out. Plug the harness in and go.
What year motors will work? I have asked this question and been told 92½ to 93½, 92 to 94, and 93 to 93½. Which, if any of these is true?
I thank the Ford geniuses in advance.

If you want a simple, plug and play, engine swap, get another 93 5.8L from a F250. That way you know that all the stuff is the same. Any other year will have slight differences, mainly to the emmisions stuff. F250s have the dual thermactor system, f150's have the single. They would not be plug and play, unless you took everything off of the old motor and bolted it on the new one. If your just looking to replace the main part of the engine( longblock) any 5.8 L from 88-up will bolt right into its place.

I've had good luck with used engines and long blocks both. If you buy a used engine get it off a high volume dealer that has several to choose from and make sure that you get a guarantee (and that they've been in business awhile). I can buy 150 mi. away in DFW for ~$500 but a premium long block would only cost $750 (cheaper ones ~$575). Either way, I save my core until I get the truck running. I have no idea what I might need later for parts. If you are willing to swap over emissions, intake, exhaust, etc., you basically put in as much labor as a long block. Problems can occur. Hard vacuum tubing breaks easily and exhaust manifolds are prone to crack. If you can find a close match with low mileage, it will swap as fast as possible. You are still at risk but I occassionally get bad long blocks too. Some people (including me) have totalled low mileage trucks with good engines. They are worth selling and using but you have to find them. I've also bought long blocks bored 0.080" over too. So where ever you get it, talk to them enough to find out if they are trustworthy and reputable. Good luck.

I like to go to towing yards that have a small salvage yard on site. Usually the motor is still in the vehicle so you can hear it and check for blowby. The last motor we bought they even had the compression checked and written on the valve covers with chalk!

thats what mine was a repo or impound next to a towing yard, it ran great til it warmed up, just saying that sometimes it is worth it to go new but either way u take a risk, new with warranty i recommend b/c i built my own to save a few bucks and it ended up spinning a bearing and the rod bolt broke and i had no warranty

I don't have experience with Ford reman. engines because they are more expensive. If the warranty is longer than an ordinary remanuf. engine it could be worth it though depending on the price. I would think Ford subs it out and somebody builds the engines to their specs. Should be a quality engine or they wouldn't put their name on it. They do have problems sometimes even with new engines but considering the quantity sold and human error involved (and internal parts can fail too), I'm surprised we get so many good engines. Anyway my main point is that a remanuf. engine is just that and when done right will perform right. If somebody else remanufactures engines to the same quality standards/specs and uses good parts, it should be as dependable and at a lower cost. Plus you don't have to go through the dealer to get it.

Actually the "Motorcraft" reman is about 300 more than Jasper. But it comes with 3/36 parts AND labor (and towing) warranty, oil pump, water pump, valve and timing chain cover and spark plugs. The dealer said the 5.4 even comes with oil and filter!
I have heard they are done in Mexico or some crud, but I just wanna drive it! If Ford stands behind it, I suppose that it will be fine. It is $2300 from Ford.
Thanks

If that is installed price it will be a good deal. Part of the price is the warranty. Be sure that you follow their maintenance schedule and keep all receipts. Otherwise they might try to renig on you. Don't get me wrong I drive only Fords, it's just that I don't trust dealers, don't need a warranty if I get a good product, and don't like spending $$$$$.
