What Year Powerstroke is Best

Ahh, some info, but you must consider that this guy's main business is rebuilding 6.0L Ford diesels.

So of course he'd be slanted towards that motor.

Mind you, I don't disagree with his assessments on many of the different motors but still, he's selling 6.0L rebuilds.

Nice to see my friends still remember...There have been several revisions made by Bosch on the fragile CP4.2 pump...

Believe so. The CP4.2 on the 2015 Dmax physically looks different than the one used on 2011-2014 trucks. Failures rates on 2015s seem lower (have only seen 2-3 reports) but hard to compare since they don't have a lot of miles on them.

Ouch! Just from memory, believe Ford had said that the stroke was longer on the improved 2015 CP 4.2 pump.

I was hoping that this meant they had finally put a connecting rod pin into the thing so the pump piston could NOT separate from the rod and pound the piston into oblivion.

The cp4 pump still uses a spring to push back the intensifier piston just like a cp3 pump does

LOL, 1 1/2 years after I bought my truck in large part due to the CP4 pump improvement "mystery" the same lack of information is still out there, and there are still failures occurring. I feel very good about my purchase!

Thanks for all the comments though none give me a warm and fuzzy feeling. The dealer quoted $6900 which I thought was high but I can see the even higher figure now. It seems like all have similar problems. I'm trying to get the BBB to arbitrate. Is there any articles out there that defines the problem that I can use in my defense? My dealer in Hutchinson Ks dumped me; I'm on my own. Wish I would have know before I bought from him. If I fix cheap and dump early what is the best buy now?

Thanks,
Jeff

I would recommend a 2013 and up Cummins 6.7L. 2013 was the first year of the addition of DEF which drastically reduced/eliminated the soot/excessive regen issue. One of the major advantages of the Cummins vs the Powerstroke and Duramax is the fact that it uses the Bosch CP3 HPFP which is much more reliable than the CP4 that the others utilize. It will also not trash the rest of the fuel system in the event that it does fail. The 2 stage exhaust brake on the Cummins is second to none as well.

I owned 3 Fords over the course of 20 years including a 7.3L and 6.0L diesel until I bought the truck in my signature early last year and I have absolutely no regrets with the decision. It pulls our new to us 16k fifth wheel better than the Ford 6.0L pulled our former 12k fifth wheel and gets better fuel mileage doing so. Mountain passes are now a pleasure with the exhaust brake.

Again, good luck with getting your truck back up and running.

Unfortunately I don't think you have much recourse. Warrantees have stated limits, and a failure such as that is very unlikely to have had any impending signs of failure before you purchased it.

Have you had your dealer check for gas in your tank? These pumps will self destruct with a good dosage of gas.

If buying used, I would say the best first generation trucks with the DPF is the Duramax trucks. I would stay away from the 6.7 cummins or the 6.4 PSD, but I would highly recommend if going with a DPF equipped truck is to go with one that has DEF.

Jeff, I feel for ya man. I kept thinking it would get better... It's a new motor!!! I did oil changes every 3500-4000 miles. The thing kept making oil... New fuel filters every 5000. I used a diesel additive based on lubricity tests that most of us saw on this forum. Drained the water fuel separator monthly. To no avail... Cut your losses and get a different truck. SO happy I did. Best buy? We're all hoping ours is the best... so far so good with the RAM at 25,000, 5000 towing.
