Thanks Mike, yes the engine sounds very healthy and never gave any sign of being ill. Pulls nicely through all gears and no bad noises.
As I do not have a garage nor tools / skills, IŽll have to let an approved Porsche shop do this. Looks like you know your way around these motors
IŽll keep this thread updated at all times, as others most likely will experience this in the future and it could work as a reference to some..
