We just got done doing an engine
rebuild due to oil pump failure. Now with refreshe engine i am still getting low oil alarm when stopped at a light after engine has been running for 30 min on the highway. It is an 2007 yukon denali xl with the 6.2. We had block cleaned, new bearings new (went with L9 cam), replaced everything but the pistons and valves (did lap them)(did do new rigs and cross hatch), vvt delete, went with high pressure oil pump and this was the same issue we had before rebuild. Do we need to chanfe to a thicker oil because of wear and tear? Has 169k miles.
