Yes the gearbox hasn’t missed a beat since you suggested cleaning then grounds
Its having the the front discs and pads, front wheel bearings, rear heat shield being replaced tomorrow plus we are taking off the exhaust to finally sort the rattle.
i also adjusted the balance belt yesterday as it started to whine a little after the belts, rollers and water pump refresh a few weeks back and now all good.
I read the history in detail this afternoon and hidden behind another invoice was an OPC invoice showing a camshaft X 2 and chain replacement 40k miles ago so that was a pleasant surprise...with my recent belt change it’s looks like it’s had 5 belt and roller changes in its 196k mile life and three water pumps...full Porsche history up to 145k with no expense spared
lots of other stuff too
Thinking about suspension next !
