What is this noise?

My truck also makes a similar noise sometimes. I looked under the hood and my air filter box is the culprit. It vibrates a little.

I sent him a kit, hes gonna pay me later, way cheaper than a starter.

Russ to the rescue again!!! Thanks bro. We all work together to keep these gems on the road.

hmm ,y DMF is worn out (i swapped auto to manual and reused the whole assembly), but i tightened the pressure plate to flywheel bolts according to spec and with blue loctite. Could one of those have come loose? Man i hope its not flywheel to crank....
