To chime in here with everyone else, just in case we're not quite getting through to you: You need to drain your oil like RIGHT NOW. Literally, the longer you wait on this, the greater your odds of eating away the lower engine bearings. That will literally cost you a new engine, whereas the upper manifold and the lower gasket are things that you can actually replace. But don't wait a day or a week, and don't keep driving your car. Go drain your oil RIGHT NOW and don't drive anywhere until you fix this. This is an engine killer.
This is a REALLY WELL KNOWN issue, and if you get to it in time, you can save your engine. But if you wait, your car will keep running, and you'll be driving down the road like everything is fine. Your car will start to overheat if you're lucky, to warn you that your coolant is gone. If you're not lucky, your engine will die -hydrolocked- with coolant-filled cylinders.
And finally, when you do get this fixed and go to re-fill with coolant. Use green. Don't use Dex-Cool. Just use green from now on.
