M Roadster oil leak

The right side of my engine is leaking oil. I haven't dug into it yet to identify the source, and before I do I thought I would ask what experiences others have had and what the source might be. The leak isn't huge, but it has coated the right underside a bit and drips onto the garage floor when I park it. Any similar experiences?

Not sure about your S52, but my S54 has a chain tensioner on that side (toward the front of the engine) which had backed off a bit. Tightened it back up and all was good. The fun part was it was dripping on the headers.

Check the coolant to see if there is oil in it. Also check the oil to see if there is coolant in it.
Possibly the head gasket.

It is either the hydraulic chain tensioner which is located at the top right front of the head(actually the crush washer), or the cam cover gasket leaking above it.
