an oily seal somewhere

is it coming out of both exhaust pipes?

Is it all the time? I'd check compression first. oil-in-water?, water-in-oil? If it's just at start-up when cold, that's a sign of bad valve guide seals. If there's no oil/water mixture and compression looks good, I'd check the turbo seals first.

Sounds like a head gasket, but there might be a leak somewhere. Check your oil and if it looks "milky" caramel like then it might be coolant and oil. If not like canyon said it could be oil and water. I'd say go with what canyon said lol, but personally it sounds like a headgasket.

well it is usually when i start the car but today my friend was behind me and noticed that it was doing it when i was at a stop..or reving a little bit

oh yeah also just so you know my oil lines are leaking to my turbos so i think my turbos are going bad because they are sounding really rough and dry almost like there is sand in them so yeah i dont know if that helps any..

I would start there then. Maybe just fix the leaks and clean things up with brake parts cleaner or engine degreaser. A compression check will still be pretty conclusive as to whether your head gaskets are o.k. or not.
