Good morning!

 

Here is a link to an article of interest on Smarty Support that helps to explain the cause of head gasket failures on the 6.7 Cummins due to the variable vane turbos and how Smarty Touch and Smarty MM3 can assist.

 

Thank you!

Do you think that the Camshaft profile could be partially to blame? I know it was reported in the 3rd gens that the cam profile was part of the reason for the issues with HG issues.

Headlift is a result of excessive in cylinder pressures.  Boost, timing, amount of fuel being injected, temperatures are just some of the drivers behind getting headlift.

I hadn't heard that about 3rd gens. 

 

I do know that the "in-cylinder" EGR of the 3rd gen grind is gone with the 6.7 and external EGR. From what I've read the 6.7 uses a decent OEM grind on the cam.
