Has anyone blown a HG yet on these things? I haven't heard of any....
I think the rods limit the chance of a blown head gasket.Has anyone blown a HG yet on these things? I haven't heard of any....

the 6.4 had a fail safe when pressure got to high, they blow gaskets instead of create windows.Lol, the cyl pressure to ruin rods is less than the cyl pressure required to blow head gaskets.
Sad but true.
yes it was built strong. Ever time I punch the throttle on my 6.7 I miss my 6.4 :-(. canned tunning, be able to put put almost 600hp wow.Idk. I've seen 6.4's bend way more rods than 6.0's and still not have blown gaskets. They just didn't seem to exit stage right. Just bend, tick and be low on compression. 6.4 was built way to strong. Got us a little spoiled.
the local diesel tech said the 6.7 has 5yr left.

The diesel tech has no clue, he's just speculating. I'm a tech as well and they don't give us that kind of information.
But once all these trucks start getting some age on them, prices come down, and low mile 6.4's aren't so plentiful, I think the 6.7 is going to be the hot-rodder's/builder's Powerstroke..
yup, and when 6.4's are no longer anywhere near "current", and quality/OEM parts are less available and more expensive, the 6.7 will be that much more attractive
we're really just now starting to see what they're even capable of
cylinder head flow is something the powerstroke camp hasn't really ever known or experienced
Ahh come on now. It's more like people just haven't spent the time to make head flow. It's there, they just have to work at it a little. How you think that big white pull truck does so good!
yeah, I should of added for what its worth lol. pretty much just a guess.The diesel tech has no clue, he's just speculating. I'm a tech as well and they don't give us that kind of information.
