Looking to buy a 6.4, how many miles is too many?

[Tinkerinmatt]

The 7.3s have proven they can go 300,000 with little issues, but I want a newer truck, I know the 6.0s have a ton of issues which can be prevented with $2000 or so, but dont want to have to immediately tear the heads off a "new to me" truck. Im looking at 6.4s but dont want to spend more than around $12,000 for my diesel. Ive found a few with between 160 and 240,000 miles on them, and want your expert opinions on how well these 6.4s have been holding up, and if any of you would consider trucks with this many miles. Will be primarily used to tow a 6,000lb open car trailer. (I know I dont NEED a diesel for only 6000lbs, but Ill be towing that car 600 miles across the appalacians to the LTx shootout in september and dont want to struggle through the hills of WV)

Also been looking at duramaxes and cummins 03-09 in the same price range, have a few months to shop, just getting ideas of what to look for now.

Thanks in advance.

I'm new to the forum, just got 6.4 back in January with 135,000 and its at almost 142,000 now and I have had no real issues. Slight radiator leak about 2 weeks in (turns out these radiators aren't so great) but Bar's stop leak worked and haven't seen a drop since 1st week of February. Just got my MBRP downpipe back exhaust and H&S tuner (I would HIGHLY recommend H&S). I would buy one of these trucks with 200k in a heart beat. just inspect it thoroughly and find out the typical issues and see if you spot anything when you check 'em out. Good luck

If you dont mind me asking, how much did you pay for it?

I am a GM guy at heart with lots of positive experience with V8 GM GAS motors. I know that the Duramax was only designed to go 200,000 miles before its first overhaul and all of them that I can find in my price range have about 200k on them. I love the Cummins motor but know that Chrysler cant put a truck around it, and am scared to take on the dangers of a 6.0. Leaves me with either a high mileage 6.4 or back to the 7.3s, or a Dodge with a stick.

Found it at a mitsubishi dealership but its basically a fully loaded lariat 4x4. came with audiophile sound system, 6 disc mp3/ cd, factory trailer brakes, power everything etc. KBB value was 29,500 dealer and 27,500 private party with 140k miles so i'm very happy with it

WOW, you got them to come down ALOT. Makes me think if I look closer to 18,000 Ill be able to get them down around my price range. Perhaps the high price of fuel right now will help my negotiations

You put a liquid stop leak in your coolant??? I have a leak as well but no way I'd do that even if I had an EGR delete.

The EGRs are already prone to clogging which will turn into a blown EGR.

1 second that^ that stuff is ok in an emergency situation or something but for a "fix" no way in hell. If it "plugs" the hole there think of what else its trying to plug... I hope u plan on doing an EGR delete real soon.... not to mention that stuff has to pass the water jackets in your engine, and I believe (if u dumped it into the degas bottle) the first place it goes is into the engine, and then through the water pump ... Dude I would do a flush with restore and restore plus ASAP and bite the bullet and change the radiator before u have many more issues on your hands.

negotiating based on fuel prices won't get you far with a dealer. unless the value of the vehicle has dropped because of it (which it hasnt). i just got lucky but the best thing you can do is get a price in your head and not let ANYONE get you above that price. when they know you refuse to budge is when they start working with you because they feel there won't be a sale unless they do. then you have the control. it took me 2 days to get that truck because i left when they refused to work with me. they called back
