For sure. I’d definitely check to see how your lifter and camshaft is first. Today I ordered about $600 worth of GM OEM parts to go back in. Hopefully it all works as it should, if so, I’ll be happy with less than a grand to get this thing back on the road. If it happens again, maybe ill considered parting this ****** out or go try and cross a deep creek lol

I’m definitely not a mechanic, but I have lots of the necessary tools to work on cars. Follow some yt videos and you’ll be fine. I took out the lifters and you can see into the hole where the lifters are and I used a scope camera to get a better look if there was scoring. Plus the broken lifter I took out, that roller was not damaged.

Pulled the head off and took out the broken lifter. Camshaft lobe is not damaged. I plan to put 8 new gm lifters and guides. Replace the 1 bent pushrod. Change the filter in the VLOM because it’s easy on the top and can’t imagine that would hurt anything. Button it back up with gm gaskets and get the HP tuner software to disable the DOD/AFM in the ecm. Then pray all holds up for some time

Lmao. That’s a good idea too! my plan is to take the passenger side head off and pray that the cam lobe is fine. If so, I’ll change the lifters on that side with OEM afm stock ones to match driver side and get hp tuner and reprogram the ecu to delete the dod/afm

230k lol took off the valve cover saw the bent rod. Took out the bent rod looked in the hole with a scope and the lifter is collapsed and fell apart when I put a magnet to see if was busted. Yup, it’s toast

Man o man, not looking good. I’m gonna take off the valve cover and see if I have a rocker/lifter issue. thanks for the reply!

Ok. Thank you. Guess I know my project for the weekend

Starts up normal. Few seconds something seems to click on or off and the pressure goes from 40 in the middle to around 60, then starts to shake and run rough. Put in a new gm fuel injector. Swapped around the spark plug, coil pack and wires. No change. compression check showed 150-160. Not sure what to do next, maybe take off the valve cover? Ideas thanks in advance

Hey Bentley, did you figure out the problem and solution. I have a 2017 Silverado 6.2 with the exact symptoms except mine is cylinder 6 P0306 fault code.
