In my experience with clutches and this goes back to my hot rod days. When revving the engine and letting out the clutch you get a point of slippage this then can cause hot spots on the pressure plate and the flywheel and usually will fade away after the engine "clutch assembly" warms up. Basically hot rodding and usually us guys like to get it on. Also, the other forum members have some good point of views. If it's an oil leak from the IMS or rear seal, you should have an oil leak so check under the engine. As I understand it, the clutch usually needs to be replaced once it has about 70K miles on it. City driving can wear on it faster.
Yeah, that is why I got one with a TIP.
