Is my turbo about to die? 2007 LBZ w/7000 miles
Hello all-
Quick question concerning my 2007 with 7,000 babied miles. I have noticed that immediatly after I shut the engine off and walk around the front side of the vehicle, I can hear a rumbling noise, that slowly tapers off. I am almost sure this is the turbo coming to a stop after the engine is turned off. I have never noticed this sound before, with this truck or any of my previous duramax's. It sounds kinda like rocks rolling around inside a tin can, that slowly diminishes. Is my turbo bearings on their way out? What do you dmax guru's think?
Thanks in advance!!
