2007 Denali Rough Idle and Stall After Running Long

[wsteele]

To this day still haven't tackled the oil issue. I'm unaware of and service bulletins related to oil issues with my motor, got a link?

Recently had to replace ring and pinion on my front differential so I've been trying to hold of on putting more money into the truck for a minute. It still leaks a little oil at about the same rate (hasn't gotten worse) 50k miles later - though my fuel mileage has gotten noticeably worse over the past year or so.

Sorry, I thought you were burning oil, the TSB is about oil usage, not leaks. Sorry for the false alarm.

I got about 250k on the clock; it probably does both. I know I've done a pressure test on this motor back when I was originally troubleshooting the issue in this thread and found I had some pressure loss likely from ring wear and/or some blowby.
