Well, we've seen our first serious 6.2 failure... The bank 1 cam is broken under the #1 journal cap...

 

Truck barely runs, pops into the intake, relative compression absolutely hates 1, 2, 3 and 4. The tech uncorked the exhaust to see if he had a plugged converter (at 5500 kms)and noticed that bank 1 converter is stone cold while bank 2 converter is hot...

 

Hotline asked for a mechanical compression test to see if the concern was "bank specific"....

 

Oddly, VCT_ADV and VCT_ADV2 both read 0 degrees.

Maybe I should have worded that a bit different... they asked for the compression test AFTER the relative compression/catalytic converter findings but before the broken camshaft finding - all the same... still pretty funny.

 

Afterthought... no misfire codes but it did have a CMP code of some sort.

The 6.2 looks very interesting with the valve covers off. The valve springs are huge compared to everything else we've seen over the last years... And the rocker arms are equally large castings.
