Spanner size for Oxygen Sensor

[Roge]

Just about to fit a Y piece, Looking into the manual it quotes a "special Socket wrench Pt No 11 7 020" is this necessary if not what sige spanner is needed. I only ask because I don't want to get it all to bits to find I won't be able to get it off. it also states a grease to be used for re assembly "Optimoly TA" what is this?

from memory its a 22mm - but its just a hex ( on the 1100 anyway )

any old copaslip stuff will do - its only to stop it heat seizing.

it's a grey, very heat resistant anti seize paste, only available from motobins AFAIK. it's brilliant stuff
