For the past few years my '03 Boxster has been leaking oil from between the engine and transmission. Last year it lost about a quart over 6 months of driving. The car has 235k miles but is in good shape and drives well.

I decided to tackle the oil leak this week and suspected it was the RMS. I pulled out the transmission and removed the flywheel. The RMS has a newer 997 part number and looks like it might be leaking a little, but not a lot. Meanwhile the IMS is caked in oil.

I was not planning on addressing the IMS because I figured after 235k miles if it was going to fail it would have already failed.

Two questions I would love some help with

1. Does this look to you like a leaking IMS?

2. What would be the most cost effective way for me to fix this leak?

thank you!
