Car leaking oil fast, need help!! The car is leaking oil pretty steadily. When the motor is running, theres a steady steam of oil rolling down the transmission and onto the ground. Its definately coming from the back of the motor somewhere, right above where the transmission bolts up, but I cant see in there to see exactly where. Ill have to grab a mirror and see what I can see. What are some things I can look for? Where might this oil be coming from? The car hasnt been modded for at least 6 months, so this isnt anything that I might have done during an install. This is my daily driver, so any help is appreciated! Thanks!

There's only a few things that can cause this...
The rear main seal is one of them. The others are a broken oil pressure sender that is leaking through the threads, or the cam position sensor's o-ring may have gone bad and is spitting oil. The only other possibiulity is the rear cover gasket is bad, but I highly doubt that, as I've NEVER heard of them failing randomly.......
Perhpas the PCV hoses back there are cracked/broken....

I've had the same problem, a leak that I could no see, but I knew it was leaking out, I thought it was the rear-main, vavle cover, everything, but it wasn't. One of the side main bolts was super loose and oil was leaking out of it. Right above/near the oil filter, I swore it was the filter, etc but it was that stupid main bolt or whatever it's called. It's the horizontal bolt goes left to right, not the ones inside the oil pan (for all the specific people) 
May be it, may not be. good luck.

Has the crank pulley ever been removed? If so, it's your timing cover seal (the seal right behind the crank pulley)...This will cause a stream of oil to run down the bottom of the oil pan, down onto the transmission....I'll put money on it...

Like everyone else stated; it could be a lot of things. The rear main would be a pain to swap on the car. I would pull the manifold as that only takes 30 minuntes, and inspect for leaks on the oil sender and cam sensor on the back of the block. I would think it was valve covers, main bolt or rear main seal as my first choices, but you never know until you look.

To answer a few questions... yes I have had the valve covers off, but its probably been a good 3-4 months since the last time Ive touched them. And yes I have had the crank pulley replaced, so thats an interesting thought as one of you mentioned... And its definately motor oil, theres not much auto tranny fluid in the T56 
Ill pick up a mirror tomorrow, and see if I can get a visual on the source of the leak, and go from there I s'pose. Ive been so busy with work lately though, its hard to find free time to start pulling things apart, so itll probably end up at a friends shop, and see what he can spot. I also installed the LS6 intake, but again, that was probably 6 months ago, but I guess its possible I could have done something to eventually cause a leak/failure of a seal or connection. Ill let you guys know what I find out though, and thanks for the good replies!

Im also a little curious why the 'Low Oil' light didnt come on? I know its not an exact science, but missing 4 quarts is pretty darn low! The oil pressure gauge didnt show any change either... 
I guess they dont call them idiot lights for nothing!

Well I do now! I feel just a little on the stupid side. I just assumed he didnt check my sig, and assumed I had an A4, wasnt really thinking what type of fluid was technically in the tranny... so hopefully I didnt come off as too much of a smart ***

Welp, the dealer called me this afternoon.... cracked oil pressure sender. Glad it wasnt anything too serious, and hopefully all is well internally. Thanks again for the help and suggestions, guys!
