Today I did a Diesel Purge, changed fuel filters, and cleaned my banjo bolt to try to improve performance. While I was watching the engine run during the purge, I noticed the rocking of the engine made my air cleaner unit hop up and down, causing some noise.

Upon further inspection, I noticed it was not properly bolted down. I took it off and found that it had rocked so hard that the rubber mounts were ripped clean in half. What's more, there was an air line that connects to the bottom which had been rocked right off, leaving it just dangling.

At the moment, I'm temporarily gluing the rubber mounts back together until I get new ones later this week. However, I'm wondering about this air line that comes straight out of the bottom. It goes down to what looks like the tranny? It's hard for me to tell. There also seems to be oil leaking into the air filter from somewhere.

What would be the effects of this air line being disconnected? I haven't put everything back together yet, so I'll know soon enough if there's improvement when I reconnect it, but does anyone want to take a gander at it?
