Some of the tools can be fabricated or substituted. the new timing belt and trying to line up the timing marks, the cams would not stay in place, they kept. Then put the second white line round the mark on the cam pulley. Anyway, I am fairly comfortable with the timing marks lining up, but will check again this evening. NOTE: The lug of the belt tensioner must not be hooked into the sheet metal cover during timing belt installation.
