I left it for about a week with a 1/4 tank. When I came back, to try to start it, it kept cranking and cranking and suddenly it made a loud POP sound from the drivers side of the engine close to the steering wheel. After the pop sound it hissed a little smoke. I thought to myself "WTF?"

so i popped the hood to find smoke seeping out of a crack in the rubber part of the intake (looks like an acordian as someone described).

what could possible have went wrong?

thanks

also, I smell something burned like a burnt clutch (however, mine is an auto) or burnt oil.
