Misfire, no light, no stored or pending codes, rattling/grinding noise.
It started with a light tapping noise, now the noise is worse if its the same thing making noise. It's kinda like a ratting grinding noise. It's misfiring under load only. I've been looking around and aiming towards the VVT Solenoid but I'm uncertain. I have a few videos that hopefully can be uploaded. 2003 162K miles, stock everything, religious oil changes. Only let me upload RPM plunging, I"ll try again tomorrow with engine bay one.

Update***. I did the timing chain job. Still has the same noise. The secondary tensioners were a little worn, but not enough to make that obnoxious loud noise. This is frustrating. I feel like if it's coming from bank 1, the sound is coming from the intake manifold. It gets louder with RPM change. My buddy did find very light metal shavings on my oil pan. So I might sooner or later have to replace whole engine.
