Hello! I've bought another car, but I didn't see on the site where to add it to my other car. The new bought car is a 2011 GMC Tahoe Denali Hybrid, with a 5.3 motor, 4.4, and 166,000 miles. I recently had to replace the lifters and have the valves ground, etc. Also put in a new oil pump and new o-ring on the oil pickup tube. The problem is that when the engine is cold it registers at 40 but when warmed up it goes to a little above 20, and stays there whether just getting out of auto idle or doing 65 mph.
The symptoms confuse me because the 20 plus is only when it warms up. Is this an oil viscosity issue or a crankshaft bearing issue or what? In my area there's no one with a good scanner or diagnostic tools except a Chevy dealership three hours away. With your knowledge base and experience your recommendations would be most welcome. Thanks!
