Just a quick one... can't seem to find reference to this under forum search.
When I took the exhaust manifold off (along with supercharger, alternator and various other components) I noted that the connection between the exhaust manifold downpipe and the main exhaust system didn't have a seal/gasket of any kind. There is a rotating flange fitted to the main system. The joint is bolted together with two long (8mm x 55mm) bolts which I will replace, along with new nuts.
I can't find any kind of seal listed. The 'C230 Haynes manual (closest Haynes offering to my CLH230K engine) says... when disassembling recover the gasket where applicable which doesn't help much.
Now I'm refitting it the manifold what's the deal here?
I suspect that if I use some kind of paste it may degrade over time and leave the joint blowing through a gap in the sealant.

- Assemble the (downpipe to main system) joint with no gasket and torque up to recommended settings?
- Assemble the (downpipe to main system) joint with a smear of exhaust sealant (paste) and torque up to recommended settings?
