Spongebob, On my 06 LBZ I had a leak that appeared to be above the oil filter. It was actually the coolant hose to the EGR cooler. I was not happy with GM when I found a standard 3" long 5/8 heater hose was stuffed in the HOT valley between the heads. I replaced the hose with a piece of CAT sylicone hose. 22 dollars for one foot at the CAT dealer. I would check that hose for a leak before tearing anything apart.
Good luck
John
