I have an 85 1800 OHC engine and I (surprise) thrashed another set of head gaskets. Anyway, I forgot the secret Subaru Ninja magic for sting the cam timing. I set the engine at TDC and aligned the timing mark on the driver side cam with the notch in the plastic cover. Then I rotated the motor 1 full turn, alinged the timing mark on the driver side cam with the notch in the cover and put it all back together. My valves aren't hitting pistons but my motor will not start. I remember something about the three hash marks in the flywheel and I think that's the trick, but I don't remember the exact details.
