2011 Buick LaCrosse cxl is making a slow ticking/clicking

Customer Question

2011 Buick LaCrosse cxl is making a slow ticking/clicking noise. The noise seems to be slower than the engine but will speed up on accelerating, even then its still slower than the engine. The noise is consistently the same cold start or warmed up. I have listened to it with a stethoscope and it has a metal sound. I am using the stethoscope in the video to pin point the location where it is the loudest.https://www.youtube.com/watch?v=oLquxEVqyjA

sounds like timing chain slap to me...but the audio file is not the best

Customer: replied 4 months ago.
If I thought it was timing chain slap I wouldn't have ask on justanswer.com. there is a distinct slow cricket sound on the audio it can't be missed. I'm stumped.
