Nabend Forum. I have now made my C20XE and want to take the head off. So I have now finished everything down timing belts V-belts away and valve cover is also down. so far so good. Now in the clever book (Opel Astra F self-help or so it is called) I should now take off the camshaft wheels by holding with a matching hexagon key to the wheel. But I don’t understand that because I thought this one hexagon screw fixation for the wheel i I hope you can help me get the two wheels down. LG and thank you so much
