I have a 1981 Prelude with the 1.8L (1751 cc) and am trying to find out where/what are the timing marks for the timing belt. There's the word "up" stamped on the cam gear and with that straight up (in relation to the top of the head) all 3 valves of #1 cyl are closed. But I need to find a diagram for the various marks for timing belt replacement. Any one know of a website w/pics or anyone have pics they could email me? Thanks in advance...
