You're looking inside of an F-150. Took two of us over an hour cleaning it out and finding all the shorted wires. The bottom of the engine bay was all sealed off with mud balls, nuts, sticks and leaves.
One small-block nest site I always found before starting up my old MF-7 in the spring was inside the flywheel cover. Fist time I found it just after I started it went the stuff started flying out from under the head shroud. I shut it down before it got to operating temperature but another friend with a larger JD wasn't so quick. He ended up needing a head and valve job when all the nest components plugged up the space between the fins on the JD's head.
On my MF-7, the nest was there for three out of four springs!
Just found this one........
