Oil pump went out on my V10 SD. The engine seized up. Truck is a Crew Cab 4X4 in very good condition (with the one minor flaw). What do ya'll think the best way to go from here is? Rebuild, Short Block, low mileage engine from a wreck, possibly replacing the V10 with a diesel?

I would imagine it is a toss up between the short block and the rebuild depending on how much time you can have it down. A low mileage swap may be worthwhile if you get a good deal, but you may wind up in the same place in a few months.

Converting to a diesel would be a daunting task as you would probably have to replace everything from the fuel system to the exhaust and possibly much of the wiring at the engine. transmission? (this is all speculation, however)

How many miles on your engine? I have a V-10 also.

My 2000 F250 SD V10 worked nearly perfectly for 120,000 miles before we sold it. Sorry to hear about yours. But since I'm admittedly not a fan of diesels, I wouldn't try the diesel route. I would guess a rebuild might be more costly because the extent of the damage isn't known until they tear it down. Tear down labor plus parts plus build labor.

Start with a short/long block....I think you will spend just as much money rebuilding and you will be happier in the end. I have seen some low mileage take-outs on Ebay, might be able to find some at some local yards as well. How many miles did it have when it seized? The V10 is usually a very high mileage engine before any issues...beside spitting plugs I guess.

Same tranny as the diesel by the way (4R100, depending on how old it is)

Are you going to do this work your self? If not, and you decide to go to a dealer, you can get a reman engine, plus you will get a warranty on it. As for the best route, i think rebuild or short block would be cheapest. That way, you can re-use most of the parts you already have i think. As for replacing with a diesel, you will also need to work with the suspension and who knows what else. Its kind of like making a 4x2 into a 4x4...possible, yes, easy....not really.

Thats wierd, i have never heard of a pump failing. That doesnt mean much, though.

Short blocks look they are running around 2500 - 2750. Found low mileage complete take out engines (one had less than 20,000 miles) for about 3700.00 with shipping. Quick searches have shown some higher mileage (60,000+ miles) take out engines for 2700 - 3200. I'm not in a great hurry as I have several other vehicles to drive. I am going to have to have a mechanic do the work (no time and I'm not sure I still have the skills). My truck had about 140,000 miles on it. Based on what I know from other V10 owners, this was a fluke. These engines seem to have very long lives. It does look like diesel conversion would be too complicated and costly.

just out of curiosity, did the warning light come on?

Interesting case. I'd like to hear more details about the pump failure.

Was it the actual pump that failed or was it a break in some other part of the oil system?

Sucks to hear that.

Admit it though, you never changed the oil

We haven't cracked it open yet so this is mostly speculation. I was running about 80 with no load, passed a car and something "felt" wrong; no power. Looked down and oil light was on with NO pressure on gauge. No sounds, clatters, clunks or knocks. Let off gas, put truck in neutral and it died with all lights on and I coasted to stop. When I tried to crank it,it was locked. There was oil in crank case (admittedly about a quart low) No oil around or under engine. I have had no signs of an oil leak but engine does use about a quart of oil every 8,000 miles. From what I understand, this is not uncommon for these engines. I'm not real AR about engine care with this particular vehicle, but I rarely go over about 7500 miles between oil changes and usually change about every 5000. I drive lots of highway miles and never pull anything heavier that a trailer with some four wheelers on it. I've blown my share of engines when I was younger. I know what it usually takes to trash a motor and what one sounds like when it goes. This one caught me completely by surprise.

Wow...yeah, mine burns exactly the same amount of oil too.

Putting a diesel in would cost a fortune, I would go with a shortblock.

It is interesting you said you never went longer than 7500 miles for an oil change. The owner's manual recommended interval for normal use on my 2000 V10 was 5000 miles. Heavy use had a shorter interval. I was disappointed in the short interval because my Jaguar had a 10,000 mile interval. Our V10 was definitely in the normal use category and we changed oil consistently at 5000 miles.

I'd say you did NOT change your oil frequently enough since your oil change interval was longer than what the factory recommended.

Would not changing the oil at proper intervals lead to premature failure of the lubrication system?

My intuition is that it would lead to sludge in the oil lines and faster wear on engine components.

What kind of oil were you running? Some synthetics will go that kind of mileage.

I doubt it.....seriously. Even conventional oils should handle 7500 miles without any problem whatsoever.

Perhaps the Ford V10 isn't as tolerant of dirty or degraded oil as other engines. Why else would Ford specify 5000 miles as the interval? Maybe this engine, with 10 spark plugs and 10 combustion chambers generates 20% more crap than a V8 running the same miles. Hence a more frequent oil change interval.

It could also be that occasionally the filter wasn't performing adequately. One result could be reduced oil flow.
