Here is a video of it, but you may have to turn the volume up loud to hear it.
I took my wife's Durango into the dealer to have new plugs, transmission flush and shocks put on. After they had the Durango for 3 full days we get it back. As my wife pulls into the drive she hops out and tells me it is making a funny ticking noise that speeds up when you accel. I hop in, listen and sure enough her hemi is now making a ticking noise.
Hopefully someone can tell me some thoughts on what it might be as tomorrow morning I will be returning to the dealership to tear someone a part. I didn't leave my wife's suv there for 3 days and spend $$$ to get back an engine with a ticking noise.
