Need Engine # Decoded

Hard to read though....

I recently got a 2001 boxster that the PO states had a new ROW 'S' motor (I assume 3.2l) installed 10K ago.
The engine code is:
M96/2167Y09654
I've read through some of the helpful posts here, but can't figure out where this one fits due to the included 'Y'.
It's suffering an oil leak on the right side, and I'd like to know as much as I can about the motor before having it diagnosed/repaired.
Can anyone help me understand the engine size, year, and possibly IMS type?
Thanks!
