I will say that cummins implementation of the CP4.2 asymmetrical pump was a disaster and not sure why this was required, but may have something to do with the fuel pulses/load on the pump with the 6 cylinder firing order setup. Anyways it just shows any manufacturer can implement a change that wasn't tested thoroughly and it backfired on them.

So Ford doesn’t have any loos of power issues with the CP4.2??

I didn't say that. I'm sure there has been and lawsuits that followed.

There is a member here that I while back stated that cummins doesn't make changes by implementing new technology fast and lets the other brands be the guinea pig before switching over and now we know cummins implementation of the CP4.2 has been terrible which discredits his statement.

LOL, they still have a much better track record than the blue oval with overall diesel reliability. The 6.0L, 6.4L, and now who knows how many versions of the 6.7L now speak volumes. ;)

Ford builds a beautiful truck but their track record on diesels since the 7.3L has been pretty sketchy. I don't miss cleaning up dripped oil on my garage floor and being nervous about taking road trips one bit since making the switch to Ram/Cummins!

When your truck reaches 225k miles let's talk. My truck currently has 228k miles and the engine hasn't been touched including water pumps.

I believe the 6.7 cummins is now at a Gen 3 including those hydraulic lifters that don't like 15W40 oil. :W
