I have an 97 850R, with 78,000 Miles the car. I looked under the car before I changed to synthetic and not a drop of oil anywhere. I changed to Mobil 1 and 500 miles later there is oil all over the place and not to mention the stench of burning oil raining onto the exhaust. I attached this picture from a previous post to show where the oil is dripping from, it is also coming out from the back of the engine where you can see a few teeth of the flywheel.

What should I do or what else can it be?? (besides shelling out the coil for a rear main seal job) Change back to Dino??

I know it is not the turbo return line because I wedged some paper towels at the bottom of the turbo and at the return line into the engine and no oil was on the rag. Placed some rags at this weep hole and below the hole where you can see the flywheel and these rags were soaked with oil.

Any suggestions will be greatly appreciated
