im assuming that its an oil seal since when i take out my spark plugs, its soaked in oil. If i clean it up and put it back in then start the car, turn it off then take out the plugs, its soaked in oil again.

I am not really concerned by this since the car is showing its age and it has 200k miles on it. What im more concerned about is oil leaking past my flywheel, going to my clutch, making my clutch slip really easy (i cant have fun driving the car to much anymore). I did replace the rear main seal. From what i heard is that there is another "seal" behind the rear main seal that is kind of hard to get into. Anyone know what this "seal" is? they said it holds oil too.

that is the only main problem in my car, minus the coolant leak that i need to fix on the lower hose and the annoying vibration the car makes 'coz of solid/welded steel differential mount.

yes, I am aware of rotaries burning oil but i thought burning a quart per 500 miles only applies at fresh new/ rebuilt engines.
again, correct me here if I'm wrong.
