Re: noisy clutch
Here's a shot in the dark but it has been known. Oil contamination can cause it but, more likely if it is a deep groan with no associated judder (yet), especially as it goes away with increase in temperature, is a slightly loose or worn engine/gearbox mounting. The groan is caused by the slight movement with a lot of power behind it.
As i said, a shot in the dark but not unknown. If it feels like something is moving then it is more likely. If the clutch disengament is rough then it could be it.
But if it goes away it could also be a case of nothing wrong, cold components, deal with it. Porsche 911 GT3's were known to make horrible metallic clutch noises.
We have no plan, therefore nothing can go wrong (much)
And i Have finally put piccies of the silver one on!!
