5.3 Knocking?

[allen1090]

First of all, here is a video

Very noticable at 36 seconds. Only on drivers side. (sorry about the sound)

 

Engine is basically stock, I have a BB tune. Engine is around 134000 KM, knock has gone from nothing to my buddy sitting in his car beside me complaining about it within the last ~20k km.

Oil is always changed when the oil life manager shows 5-10% using Mobil 1 full synthetic and a NAPA gold(wix) filter.

 

Is this the famed GM knock? Is it fixable? Or is it something worse?

I would like to get a XR259HR cam in the somewhat near future, but problems come first.

 

 

If you guys need any more info, ask away.

I recently had a post in this forum under "strange sound under acceleration". It sounds like the ticking I described, but hopefully is isn't! Best case scenario a loose heat shield or something easy to fix.
