Idle stumble when cold...And other stuff

[dhirocz]

OK so I need a new cam. Rocker was on its way out on #1 exhaust but hadn't scarred up the cam yet. But when I rolled the engine over, I found the same on the #5 intake...Which started to eat the cam.

With 685k on it I need to decide what direction to take. I'm fairly disappointed, seeing as I've made sure to change oil every 15k or less, have done multiple oil analysis done which all came back clean, run a filter mag, and run a bypass filter and this still happened. At least I caught it earlier rather than later. Had the truck since 607k.

Cam lost about .030" off the lobe.

If I decide to replace, I suppose I should plan for a new cam, rocker arms, drop and flush the pan, inspect/ replace the oil pump and replace the oil cooler...? I would also pull a couple caps and check the bearings while the pan was off.
