The truck has 127400 miles. I've only had it for a month and a half. It's had an intermittent cylinder 6 misfire. It was entirely random. I have not over-revved the truck. It also has a low load, low rpm shudder that would sometimes go away with throttle application. I thought this was the MDS but maybe not?
I took the rocker assembly off after I posted the pic. Someone has been in there before me. The rocker assy bolts were super tight. The block on top of the rocker shaft (in the pic) is broken in two pieces. The tabs that are on the retainers for these blocks are mashed and/or broken.
The bent pushrod let go on a cold startup. I'm thinking it may have already been slightly bent.
