My BJ8 has a Rawles motorsport alloy head and puts puffs of blue smoke out when it starts from cold, valve seals I expect.
I've been stoking myself up to change them and now the "virus" seems to be creeping back again I have no excuse other than I have never worked on an alloy head before. I tend to make sure that nuts are tight enough! So I'm a little bit afraid that I might do some damage by overcompensating and not tightening them enough or stripping some threads. I also suspect that the torque on the head and manifold bolts should be a lot lower than the Bentley manual indicates.
So can anyone tell me what the head and manifold bolt torque's should be. I've googled it and come up with nothing so far.
Any other advice on working on alloy heads would also be welcome.
Thanks
AJ
