Hi, i took my cylinder head of for the first time yesterday cause i had a gasket leak. now im putting back together. Im scared of the ''timing'' part of things, like lineing camshafts up and the cam chain. I have the manual and have a good idea of what to do but its a little vague. Is there anything i should watch out for and be careful of when i do this could use please give me some advise thanks cheers.
