u/Gmank47

Hello, would appreciate some help on this. Randomly started hearing ticking/knocking sound from the rear left, increasing in frequency from about 6mph. No sound below 5mph or when stopped. Didn't go over 30mph over fears it might be something catastrophic.

Upon inspection underneath, saw this oil/fluid (thick green colour) from the rear left under the car. Quick search seems to suggest it's the motor mount. Car has sports chorno pack but no PASM or PADM as far as I'm aware. No warning messages on dash.

Is it safe to drive home about 80 miles on the motorway? What could the course of the sound be and I assume the fluid leak plus sound are linked?

Vehicle: 2019 718 Cayman S. 40k miles

Thanks for any suggestions!
