i'm going to try to explain this to make it easy to understand. This is kind of hard with a press on cam gear and the engine in the car, but this has to happen. We will take any piston it don't matter witch one, but we will use no. 6 for an exsample. You've got to able to see the valves going up and down on this cyl. and tell when the piston is at TDC. We will make believe there is no timing marks on the timing gears. You will have to crank the engine, right hand rotation. Then watch the exh. valve on that cyl open and close, just before the exh. valves closes the int. valve will start to open. Now you came turn the engine back and forth and the 2 valve will rock back and forth. NOW, when they are both rocking (both valves off the seat) that piston should be on TDC. If the piston is not on TDC the the cam gear is off and the valve timing is off. That is called rocking the valve in relationship to piston TDC. NOW, that piston in on exh. stroke and the the conpanion cyl. (witch is no. 1) is on compression stroke. Every cyl. has a companion cyl. One is fireing and the other is exhausting, both pistons are at TDC. So you see, you could get the valve timing right if you didn't have any marks on the gears. Now, ain't that easy. Walt
