Tell me your horror stories (Diesel)

[ib516]

Ok, so browsing through the thread about the 2011 Ford diesel left me in shock. Seems like there were many issues with the early builds of that engine. I know the Cummins and Duramax of that generation had their own issues (mostly emissions related?).

How are the newest gen Ford 6.7L diesels holding up (2015+)?
Are their similar stories for the Cummins and Duramax in the latest gen (2014+)? I know the Cummins has been 370hp/800tq for a while (in the 2500), have they worked out the kinks in that one? Are failures common? I only know one guy with a 2014 Ram 6.7L Cummins SRW 3500. He has had plenty of recalls and was losing coolant a while back, but I think that was the famous water pump issue. He has had no serious issues. His is a 370hp/800tq version with a 68RFE auto. But that's a sample of 1 which is pretty meaningless.

I went with a 6.4L Hemi last time I was shopping as it suited my needs better and frankly, I was scared away from diesels (all of them). At that time, my research told me they weren't worth the gamble. What I mean by that is their superior towing performance wasn't worth it to me when they could cost me tens of thousands to repair if they failed, and they were all (my opinion) having reliability issues in the 2011 to 2013 time period. I thought they were mostly pesky ones to do with emissions, but I'm just not into check engine lights on new trucks.

Are the diesels getting better? Should I put them back on my shopping list for my next new truck?

I'll likely be towing under 10k GVW, and it'll likely be a TT around 30'. I do want to log some miles though, and that will include some long distance touring (cross Country type).

Because I want to.

Nothing wrong with that!!!

No horror stories here, bought my current 2003 2500HD Duramax Silverado LT new and 15 years later is has 292,000 miles and have been a solid truck. Replaced injectors at 100,000 under warranty.

Picking up a 2019 3500HD Duramax Silverado High Country Dully this Friday and plan to drive that truck for the next 15 years.

Been a hard core Chevy guy all my life.

My horror story with mine was being without her for a week last month while waiting for my custom built trans and ultra low stall speed triple disc TC was being installed. Finally got the weakest link out of the truck for the power levels I want to run.

I had to wait for my rebuilder to get someone who wanted to buy my old trans so I can use theirs as a core to put all the bilet goodies in her.

What power levels are your seeking?

Now that my father in law has a more reliable truck and we don't have to use mine as much, I am planning on doing compounds which would probably be around 700 rwhp. I am getting the supporting mods out of the way first so it can handle the power.

I assume your installing head studs? And another HPFP?

Yes, I plan on doing ARP 625s before then. I don't think I will need another CP3. I should be able to do with a stroker CP3 and bigger injectors. Nothing is set in stone yet and I may even change to a big single when the time comes.

Kosub Transmissions. Why? You want to swap out that Aisin?

NOPE!

I may want to beef up my 01 Sport with 125k miles if I put a little more power to it.

Well I am sure he can do that and beef up your Aisin if needed. He said he has already done a few Aisins in multiple brands.

I would highly recommend a ultra low stall torque converter if you do. It puts the power to the ground way better than the stock TC and requires much less throttle to get her moving. It almost feels like it is locked all the time. That coupled with the almost telepathic shift tuning Hardway performance did for me made it a much better driving experience.

Please tell who that builder was.

Oh, I forgot about my buddy’s wife’s horror story.
Traded him the old Dodge for his Titan for a couple weeks because we had a guest who wasn’t driving that big stick shift tank around.
Next time his Titan needed a repair it cost him $50k when he traded it on a new Ram Cummins!
She was in horror!!!
