Motor... Rebuild or replace?

[psychos2]

the dealer just saying the bearing was bad, and that was the cause is B.S.! the bearing failed because there is something else wrong. if it was because the bearing is bad then the other five bearings would have failed too.and the fact that it is #1 99% rules out bad bearings.you would also think weak oil pump? but from what i saw on the cd manual the oil pump is in the front ,which would mean the front bearings are oiled first.could be a lean cylinder causing detonation ,causing the bearing to be pounded to death? and another question is why are some failing and not others?i think isuzu has the answers.maybe andy from isuzu can shed some light.one last question is are the short blocks updated ,and if they are what is updated? shawn

Joe-

I don't guess you have any physical dimensions on the turbo deisel, do you? I will do some research tonight and see what I can find, but any free info I can get would be great. The TD would be ideal in MANY aspects, but again, I would question the transmissions ability to handle it as MOST TD's put out hella torque! Of course, if it can handle it, HELLA TORQUE is GREAT! You said that there's no computer involved... whay is that? Don't tell me that the TD is carb'ed... that would take lots more stuff outta the loop too! The next question would be how much of my AC stuff can be adapted to the motor... is the TD a V-6?

The warranty company told me personally that unless I find more of my receipts, they aren't even going to LOOK at it. I will be tareing things apart on Sunday after I put my son on a plane to head down to FL to visit his mother for Christmas... anyway...

If they don't cover it, I'm gonna dig deeper into the TD subject... sounds like a possibility... anyway... MORE info please?!

TTYL!

I don't have the TD dimensions but they are available from Isuzu's corporate site. They sent me a nice info packet last lear when I was compiling info for doing this with a Trooper RS. As for the computer, diesels use mechanical injection rather than electronic, minimizing the need for a computer. I have seen some use them, but not many. Keep in mind too that the 3.1 and 4.3L TD engine are 4 cylinder so room isn't much of an issue. You'd have to get a bit creative with the turbo and intercooler plumbing, but it's very straightforward. As for accessories, just simply fab or adapt the necessary brackets and make sure your cable runs are routed properly.

There was another post on here a while back about converting to a manual 5-speed tranny and retaining TOD. That would be ideal for the TD swap.
