Re: 2011 Denali 6.2L No Oil Pressure
Yup, the filter was not the problem. Its at the dealer now. Service manager was as puzzled as I was. When the pressure drops to zero there is an odd clunking you can hear in the cabin with all doors closed but you cannot hear it with the drivers door open. Its worse in gear than in park. Should know something on Monday, I'll update the thread. I appreciate your suggestions.
