Hello
I own 1996 geo tracker 16 valve EFI front wheel drive 1.6L automatic with 150K still running great, like a charm!
Due to leak in the water pump I decided to while changing the w.pump also change the timing belt. To make the long story short I made sure when removing the crank pulley I set it dead center at 12 o'clock as marked with arrow on oil pump. For the cam sprocket I realized that the E position was at 6 o'clock so I market in 3 different points in order to have it referenced. I was not aware that I had to turn the crank pulley CW until both the pulley and the sprocket are set dead center as marked for TDC. I figured as long as the crank pulley is dead centered and the cam sprocket was not moved simply I can replace the timing belt in the manner it was removed!!! So i did. Now after reading and watching tons of videos and forums I have understood that my valve timing as it is now is set on #1 to fire which should be set for #4 to fire that means I need to turn my sprocket 90 degree cw to bring the E mark from 6 o'clock to 12 o'clock! I have also removed the cam cover so that I can see and visualized the camshaft and get exact understand what exactly going on. I also did the blow test via spark plug hole and found out that the number one cylinder was already fully sealed matching the cam sprocket current position at 6 o'clock. So this is my question; should I just go ahead and replace the timing belt without touching and repositioning the cam sprocket or should I move the sprocket to 12 o'clock!? What I don't want to do is to either touch the main crank pulley that is already correctly set nor touching the distributor which is untouched. This car was a very reliable nice working car with no issues whatsoever and I don't want to do anything that ruins it …
