Buying a High Mileags 6.0

[Twincam666]

Hi all, Im looking at diesels and have seen some Higher mileage 6.0's with between 125k to 180k

Is this just too much mileage?

If I do buy one with that kind of mieage and do the deletes and head studs/tuner will I blow the bottom end out of it?


also, is there anyone doing 6.0 excellent performance crate motors out there as I've never seen any mentioned???

Since this is ultimately your call I will give you what I look for when buying a truck.

First will this truck fit the bill for what I want it to do for what they are asking
How old is it in yrs in relation to that mileage. A truck of 2 yrs with that mileage means it was rode hard and put up wet more than once. [When did it have time for maintenance] so a lot of wear in a short time span with sketchy maintenance. (minus).

Either way a lot revoloutions = lots of wear not only on engine but entire drive train. With that in mind I would assume it will need an overhaul soon.

That in it'self may not be bad. Figure purchase price + overhaul cost am I still cheaper than buying a newer.less mileage truck.

Thats how I look at it anyways.

You have to judge off what your looking at, in relation to what the above said, if you've got a beat up 2007 with 190k on it, it's probably someone's work truck, if you find a 2004 with 60k on it, your probably into either someone's extra vehicle only used for towing, or a truck that was broke most its life...

Mines a 05, with 72k when I bought it, perfect inside and out, lifted since 20k miles... It was someone's truck who does exactly what I do with it, drive around town.. No long haul trips, just cruising around, it had never been tuned, and the oasis report was relatively clean... So I was comfortable paying what I paid, had this exact truck had 140k on it, I still would have paid a good amount for it... Had the interior been beat up, and all dented outside, I would have just passed it up, even at 70k miles

I argree with what the above posters have said, buying a high mileage truck in and of itself is not such a bad thing, if you know the maintenance that was done (the 6.0 is a very maintenance specific motor). What does the body and interior look like? As to blowing the bottom end out, I am currently rebuilding my 03 6.0, and looking at it, I honestly think stock bottom half could handle over 700hp, that block is built tough, the top end is where it would go, head bolts and head gaskets. Also it all depends what you want to do with the truck too, as to whether you are getting a good deal

Don't be scared usually the higher mileage 6.0s have the problems worked out or didn't ever have any, also a high mileage 06 or 07 would had to have a lot of highway miles which wouldn't be as bad as stop go city driving
