High Mileage 6.4's?

[DirtySouth85]

I'm looking at buying an 08 6.4. I switched from my 6.0 to a Duramax and I love my truck, but it just doesn't ride as nice, and there isn't as much room in the cab as my old 2006 had.

I'm a little nervous about jumping into a 6.4 with 90K+ on it. I will tune it, and even though it won't be as fast I think I'll like the truck over all a little more.

So, I'd just like to know do's and don'ts as well as how long tuned trucks are lasting with sensible drivers. Thanks for the help guys.

I have 160k miles on mine been tuned since 100k with no problems

How about anyone else? When I do get it, should I do anything specific, Like change the radiator bottle cap? Or anything else that I might have missed.

First off..I came from an LB7 and an LBZ Duramax. I looked at your mods and I promise if you drop the same amount of money in a 6.4 as you have your LBZ you will have a truck that will blister that LBZ all day long.

Have a Ford dealer pull an Oasis report on the vehicle you look at. Make sure the radiator has been replaced, the venturi-t has been done and you have both new stlye upper and lower radiator hoses.

My truck has 119k on it and has been modded since 115K.

I bought my truck new in 08, drove it stock for around 65,000kms, then bought an edge race evo & dpf/cat delete& drove it with that for about 30,000kms. It changed the truck & I never looked back. I recently put on a mini maxx & egr delete & now have 112,000 kms on the truck. It is a long ways from high mileage but with these simple deletes I am hoping to get alot of miles out of it.

This is correct do a delete and h&s programming and you'll be amazed. Whoever told you that your truck would be faster is mistaken

Lol, that's funny. And no mistake was made, and it's been proven against 3 different 6.4's. All 3 had spartan tuning

I said h&s for one, but there's no way just search the forums not to mention you tube. Maybe you raced a 6.4 with a bully dog.
