- Talk about bent rods due to a hydrolock is just silly. That would be like saying the GM interior plastic is inferior when it melts after the ensuing fire from rusted fuel lines.

Word on the GM truck forums is that the Duramax will see an update in 2017 to around 445 hp and 850 torque. I guess time will tell, as always.- Any rod will bend if the cylinder has liquid in it.

Two more things , 1 if these engines are so great and these trucks have gotten expensive how about more warranty ? Not many guys want to own a modern diesel out of warranty. 2 if Ford really wants to appeal to the commercial market, make a tilt front end so if and when things break you can get to them
What are they going to do about the connecting rods. Was looking at pictures this morning of 6.7 bent connecting rods. The 6.7 rod is smaller in the rod area than the earlier powerstrokes. Rod bearings are also not keyed. What keeps them from spinning bearings.
Some things are great in the 6.7, like air/exhaust flow direction, individual rocker arms for each valve, giant lifters etc, but if they leave an important component like the connecting rod lacking, then the whole engine becomes lacking. The aftermarket is already into better 6.7 connecting rods, which is telling.
Do they need a operator warning "If hydro-locked, do not attempt to turn over!"?
Chris
Rods on the 6.7 PS do not seem to be lacking at all. H&S pushed their test truck to over 1600 ft of torque and drove it home. The size of rod is not really a big deal, metallurgy and design are just as important.
H&S test
H&S still use this truck daily. You can get aftermarket rods for anything.
Yeap, I looked at one site that had a set of 8 for $3400! ChrisMe Again wrote:

They don't have any money for investing since they are about to get sued big time for their ignition problems on some cars they made in the past.

Ask any higher volume diesel dealer or just call their parts dept. We run 8 Ford trucks and almost always have at least 1 in the shop so I talk to my mechanic weekly.Ford has been the less of the evils for us but only due to having such a good relationship with our servicing dealer. Right now his dealer has 4 6.7 trucks that have been there for over 3 weeks waiting on parts. Once I can seem to get ahold of more info on the fuel system I will post it.
Fords web site has some bland info on the new trucks http://www.ford.com/trucks/superduty/2015/
I want to say the rod issue is mostly in the early 11 units
I highly recommend you obtain some scuba gear and some lessons...the BlueKoolaid crowd will be along shortly to drown out your claim...:B

You mean the ones that dropped valve, and they then bent push rods? I would think those we the ones the windowed the block!
