Just this morning I went to fire up the truck and it now has a rattle coming from around the front of the engine. I'm really hoping it's not timing as I don't currently have the funds to fix it. Sorry it's kinda hard to hear over the typical 22r valve clatter.
what do you all think it is?

 

Update: definitely not the timing, took the cover off and they look brand new, the chain tension is good too.


Fired it up after and the noise is gone

 

Sounds like a normally operating 22RE to me.

 

Water pump bearing?

 

Pull one drive belt off at a time and see if that alters the sound. When you pull the waterpump/alt belt don’t run it for very long.

 

I wouldnt guess valves, but wouldnt be bad to check.
