Got a 92 Loyale EA82. Replacing all the seals, belts, pumps, etc. I've removed the cam sprockets to replace cam seals, gettin ready to put it all back together, and now I notice that in my manual it says to line up the marks on the cam sprockets to the notches on the top of the t. belt cover. But there are no marks on any of the sprockets whatsoever. So whats the best way to go about getting it back in time? I don't want to take the valve covers off to do it that way. I've heard that you can put your thumb over the spark plug hole in cyl 1, turn the crank and stop when you feel pressure. But how do you know if it's on the compression or exhaust stroke? Can anyone walk me through this?
