Gah, first problem with the SST.
Got home last night and left the car ticking over while I opened the garage door. When I went back to the car I noticed quite alot of smoke coming out around the bonnet. Drove the car quickly into the garage and got the bonnet up.
The smoke seems to be coming off the body of the turbocharger itself. I checked the obvious things like a leaking rocker gasket and the engine seems to be oil tight. There's no oil dripping onto the floor so what's likely to be the cause?
