Claus,

I found some o-rings marked for the cam housing from one of my 907 gasket kits.  Trying to match it up it by eye the o-ring appears to be a dash no. 11 buna-n.  I am not sure that the o-rings in the overhaul kit are those specified by Lotus which I assume would have been 8.0 mm metric?

Thinking about this, who cares if it fits sloppy over the roll pin.  The seal between the cam housing and the head is whats important.  It appears to me that the cross section diameter is more important to give the proper interference fit between those surfaces.  Just my opinion.
