i have oil coming out the dizzy end of the head. ive changed the O ring seal on the dizzy but its still coming out and apart from not being good sign it is making a mess of the bay!!

ive check my trust haynes manual but as usual could find no info (may just be me!!)

ive found out about the cam seal on the pulley end but is there one the dizzy end? if so how hard/what are the steps to replace it?

cheers

PAUL
