Hi all, Many thanks for the help. Found it exactly where John+4 said. AJ advises against its use but I guess I will try it once just for the hell of it. Also the old owners hand book says do it with the engine cold I assume this might eleviate the grease being melted by hot oil !!.
Also to be sure I assume one does it after start up, oil pressure being needed to make the concept work?
Regards Huddie.
ps I will add some pics of my car when I sus out how to do it.
