Hi Stig
Can you fill in some gaps? Looks like you bought your S 6K mi after the rebuild. Do you know why it was rebuilt (bore scoring or something else)? How do you drive the car - track, fun runs, daily, etc? Do you drive it in cold weather? Also, assume you meant you have a 3.6L displacement now - 3.2 punched out to 3.6.

I ask because I've had a similar experience w/ my Cayman S Sport. Engine rebuilt 2021-2022 because of bore scoring and shouldn't happen again. But it did.

What you need to do now is scope the engine and see if there's scoring in 1 or more cyls.
