Emissions issues and CP4 are the downfall on both Ford and GM trucks. The GM front end is going to be lower maintenance and ride much nicer than the Ford.
Lots of guys seem to be having decent luck with the 6.7 Fords after the rash of engine failures for 2011 model year.
As far as the guys who keep pushing to look at the Ram, The 6.7 Cummins are slightly notorious for HG failure and the 68RFE is nothing to write home about.
The only people who are having HG issues with the 6.7L Cummins are those who have large tunes on the truck. They are NOT notorious for that issue. Although I don't have the 68RFE trans, they have been out for almost 10 years now and have been pretty good for the most part. Some have had issues with them but there are no real common issues.
The Dodge tranny is still not up to par with the Ford 5r or the Allison. And yes, stock trucks are puking HG on 6.7 Dodges. The Siamese bore and minimal HG material between cylinders couple with the VGT/high cylinder pressure is just a bad combo. I've just done my first one, the machine shop I use says they see alot of them, and they seem to have valve guide issues as well.
I agree... the 5.9 rarely would blow a head gasket but these 6.7 cummins have issues especially when pulling a heavy load. Install a tuner and its' almost guaranteed to blow that head gasket.
I'm not aware of the valve guide issue... Is it because of the regen process?
