I was asked about how to time the Protege alot. Here is a help thread,

You have to make sure that all three timing marks line up. There is one on the crank pulley as well. There should be a series of lines and numbers on a raised wedge of plastic near the bottom of the motor, it might be dificult to see as you have to look down where the mess of belts are. There is a dash line betwen the two belts on the crank pulley. Use you hand or a long ratchet, Short Extension and Deep Socket.

Use the crank pulley to rotate the engine Clockwise so the marks line up on the zero. That is called "Top Dead Cneter" or TDC. That means that the #1 Piston is at the Top of the stroke.

Next, you have to make sure that the cam gears are timed properly. You notice that there are "L" shaped holes on the inside of the gear. These are for the dowel pins on the cams. When the crank is at TDC, both of the Dowel Pins on the cams are supposed to be at the top, like 12:00 position. Next, make sure that the gear are on properly.

The left gear on the intake side should have the dowel pin in the groove that would make a "J" shape, top down to left so the mark near the "I" on the stock gear is facing the other gear.

The other gear (Ex) makes a "L" shape, from top to right so the mark near the "E" faces the intake gear.

The Belt should naturally want to go on with everything lined up like this.

Make sure the tensioner spring was put on corectly or it would just jump a tooth and go out of timing.

It's important to line everything up because the cam position sensor reads those stupid magnets that are attached to the gear to decide uppon timing and spark and fuel delivery... Kinna important functions that could mess shit up.

One thing is does get more tricky when it is in the car... you have to use a ruler or straight edge to make sure that you actually have the timing marks lined up when they are even with the centerpoint of the gears. That bit me the first time I timed my motor as I didn't do that check.. I had the timing marks lined up but it turned out each gear was off by one tooth... so my intake was advanced by a full tooth and the exhaust was retarded by a full tooth... needless to say the motor ran like crap and I melted a catalytic.

Yeah, you have to roll the engine by hand to make sure that the tensioner is in fact working and that the marks line up again.

Normally it's not that hard to get the first time as the teeth are rather large and it would be apparent that the "Effin" thing was out of time.

Yeah, I did roll it over, but it still lined up perfect... just "low" basically.. it was surprisingly deceiving... but being in the car and in a hurry at the time certainly did not do me any favors.

Agreed, I had the luxury of having the motor out of the car when I did it. I was able to roll it several times with the plugs out to check it all out.

carelessness and general stupidity at the time were factors as well :)
