So if I find a 6.4l that has an DPF delete shoud I think that the guy knows what he is doing or what? I heard that they put a twin-turbo system on this engine? Is that true?

 

the tearm twin implys a matched set of turbos. one for each bank. they dont have that set up. they have a set of sequential tubos. thats a very different set up. IMO I would skip the 6.4. but thats my opinion. lots of happy owners though.

 

At this point, I'm one of the happy owners. 62000 miles, only a few minor oil leaks, and now a fuel drain leak. Mileage is 11-13 in town, 13 on highway, 7-8 towing 17000lb fiver.

 

6.4L seems to be very sensitive to water in the fuel destroying the fuel pump and injectors to the tune of several thousand dollars. Drain the fuel/water separator regularly.

 

Yeah, well, now I have to replace the drain valve as it is leaking...

 

Mine did that last summer. Leaked out the drain valve and I couldn't get it to stop. It did NOT leak once the truck was running. Had it fixed under the 3/36. Paper work said they replaced the frame mounted FUEL PUMP which seemed strange.

 

Best I can determine, you can't buy any of the parts individually. someone like Ed at partsguyed.com could probably tell you.

Local parts person may not have the researchability skills.

 

you can get the WIF manifold by itself done a bunch of them.

 

good to know that you can buy just the pieces.

 

not good to know that you have done a bunch of them though.

 

I would imagine that vast majority is due to lack of maintance.
