Engine noise problem
- Thread starter josephb983

Replacement of the tensioner did not fix the noise.
Engine has 200k miles on it. Noise goes away/gets less when it is warm.
Pictures with the valve cover off:
Timing Gears
Timing Chain
Engine without Valve Cover
Does it look like my timing setup needs to be replaced?

Judging from photos is difficult at best but they look worn to me, is there much slack in them? Did you change just the tensioner, or the guide rails as well? My bet would be you are in need of a timing system rebuild, but I cannot guarantee that from a photo. Here is a photo of the system from RealOem.
It's more than likely that it's the guide, not the tensioner. You'll have to remove the lower timing chain covers to see the chain guide. You won't see any slack just by removing the valve cover. Before you tackle that, make sure it's not you fan blades rubbing the fan shroud, or something else.

I'm gonna do that next. It can't be the fan blades, as I removed the fan and the noise remained.
Here is a video of the noise when the engine is warm:
