Help!!! 06 Denali with 5.3. Using a ton of oil and occasional pressure drop. Figured it was the valve cover and possible guage/sending unit. Had mechanic change Valve cover and immediately after driving away pressure dropped and the warning popped up on the dash. Brought back to mechanic and he assumed it was a bad gauge. He called me this morning and said it was the oil pump and the engine is getting no oil pressure after warmup. If that was the case, wouldn't i have noticed the issue before the valve cover change? Am i getting hosed? He's a new mechanic i've started using, but has always been honest and fair with his prices.
