6.4 in stock is a POS. Ive read that guys who put them on a plan are doing ok, but having to take off the cab to get to the engine....No thanks
No. Injectors is a known problem on the 03-07 5.9... 06 is a electrical night mare.. the 68rfe cost an arm and a leg to rebuild, alot fail on stock power. So spending 3-5g on a 6.0 to "bullet proof" it is right around the same as the other two when either the injecters fail or the trans fails..^^ Are you joking around?
You dont have to pull the cab on a 6.0 for injectors or studs.. you have to pull the cab on the 6.4 for pretty much anythingAt least with injectors you can upgrade them while they're out, same with the trans. Bulletproofing a ford has almost no performance gains. Last time I checked, I didn't pull the cab to any injector or studding in a Dodge.
They're nice trucks for sure.If i was going to get another ferd diesel , id be going a different dirrection.. id go newer and get the 6.7
Defeats my whole purpose on going pre emission though. If i had a 6.7 powerstroke it would have to be missing key epa systems. While some people think they do good. I think they are worse for the climate, and engine reliabilityThey're nice trucks for sure.
No problems here 2007.5 3500 drw original 68REFE with 245000 miles.stays loaded and hooked to skidsteer and trailer weighting 15000lbs.big speaker magnet on trans pan ,I change fluid every 50000 miles.3rd to 4th gear really long best to manuel shift and let off throttle briefly to allow to shift and lock in.i do plan to add line pressure increase as well.with the spring and harness swap.What mods do you have done to your 68RFE?
It's the worst transmission I've ever owned by far made worse in combination by the factory shift points. I would pay good money to put a G56 in but before I go there I was going to try a new valve body and higher line pressures. I was also going to try making my own TCM tune because the ones that I have tried hold third gear way too long.
I have heard the 4.5 gen and up 68RFE are a different beast because of a new valve body and also better gearing.
Lmao, “worrying” about imaginary problems so much you’re selling the truck. i have had several trucks before landing on my 08 6.7, mine were as reliable. This truck just works. I fix what’s broke and move on. Every older truck is going to have problems you just learn to deal. Have you considered a Subaru?Ive decided im going to sell mine, or try too. Not going to give it away. Worrying about the trans and headgasket all the time when i drive it, is what was the tipping point on the decision
68rfe and head gaskets are a known 6.7 problem.Lmao, “worrying” about imaginary problems so much you’re selling the truck. i have had several trucks before landing on my 08 6.7, mine were as reliable.

With early H&S tuning, yes. Even so, common sense goes a long way - we are not in 2011 anymore68rfe and head gaskets are a known 6.7 problem.
