225k miles w/massive oil leaks
New to the sight, and new owner of a 2000 7.3 4d short box 3/4 4x4 w/auto. I got it in exchange for a few days work for a friend of mine. It has over 225k miles on it and the last 60-80k miles it was used as a ranch pickup (aka- tractor) with a hydraulic flatbed hay hauler. It has spent the last two winters idling for at least 5 hours a day. It has been hammered off road so hard that both rear bump-stop brackets are broken off even though it has "helper" springs. It does have a rebuilt auto tranny so I would like to save this motor. The problems I have found so far are as follows:
1. Uses about 1 qt of oil per hour. It has so much oil on everything that its hard to tell where any one place is leaking but, near as I can tell there is oil in exhaust pipe, oil built up all around turbo and piping, and oil coming from back side of motor (could be more from turbo)
2. Has bad misfire/lope when cold
3. Hard starting when cold, sounds like a dead cyl or two.
4. No power at all when cold. A dog, at best, when warm
5. Blue/blackish smoke, bad when under power up hill
I think it has a hypertech chip (at least the sticker on the inside of the door and the programer in the glove box.)
All of that back story to lead into my question,
Is it worth fixing the motor? If it is, What parts? (timing chains/fuel sys/turbo?)
Since I got the truck for little to nothing and have nothing invested so far, would it be worth my time to get the old girl running? I am a good mechanic and very familiar with the diesels that we used in the military, but new to the 7.3's and their computers wizardry. I'm thinking that I will do a compression test and see if the rings are good. If they are I plan on replacing the Turbo, timing chain, ?lift pump?, glow plugs, and get re-man injectors and injector pump.
Does my plan follow sound logic? Is there anything I'm overlooking or that anyone with experience would suggest? I'm not looking to build a monster but I would like to keep up with our 99 24v Turbo Dodge ranch pickup (so I don't have to hear crap about my Fords.)
Is there a good aftermarket turbo/exhaust for a reasonable price that helps with the typical turbo lag down low that these trucks seem to have?
Any suggestions would be greatly appreciated!
