    My wife called me yesterday at work about her 2007 Denali. She started it and there was some weird sounds she says. Like a diesel truck. Now the only time I have heard this is on older trucks experiencing piston slap. She said there was a exhaust smell that was very strong. I was wondering what you guys thought of this??
