Oil Leak - IMS? RMS? Please help diagnose

[sasha055]

Hi,

Past couple of days my car developed an oil leak. Just a couple of drops a night, centered under the engine.

Today I put it on ramps, cleaned the durty area with paper towels, then revved it to 6K and kept it there for about 2 min,
It started showing oil on the engine, just to the front and right of rear jacking point.
Is it IMS or RMS? should I be worried?

Car is 2000 Boxster 2.7L with 76k miles, I change oil every 6 month (~3k miles) with Castrol Syntec 10W40

Thanks
Sasha
