Please help!!!
I've let me 1989 Porsche 964 C4 sit for far too long and on starting it up, there is a very unusual noise coming from the engine (haven't been able to pinpoint location yet). It kinda sounds like a handful of big, angry bees though..... here's a link to a video with the sound.

Also, there is a ton of smoke pouring out of the exhaust.... has happened before when left sitting.
I'm reluctant to even let it warm up at this point....
Does anyone have any input what it could be? Is it ok to let it run and warm up, maybe it'll go away?
Thanks,
TJ
