I have a 95 Honda civic with a D16Z6 engine. I was trying to check the timing on the car, and wanted to get the engine to TDC. There were a few marks on the cam gear. There was no up pointing arrow, so I was unsure on which I should use. The linked picture shows the 3 marks at the top. One is a red dot. The other marks are at the bottom with some ticks and a dial looking thing. It lines up with a little notch at the bottom of the timing belt cover so I was thinking that may be the marker. There were also no little marks on the crankcase nut by the bottom of the car. Any help would be nice! Thanks.
