yep looks like that would be your problem though this isnt really "jumping timing" this is more of a failed timing belt let us know how it works out for you after you get it going

Yes this belt explains a lot. I suspected it from the beginning and had started there, but then I read that this motor does not jump time and then I opened the oil cap and saw that the lobes were turning so I figured it was OK. Last thing I ended up checking other than distributor problems was this....go figure! The missing teeth would explain why it occasionally sounded like a car with no plugs in it when I would try to start it as in too fast a starter rev from the starter on the motor. The cams verses the crank were assuming all kinds of new positions. Lucky for me this is a non interference engine or I would have been screwed. Looking at my other vehicles now for timing belt replacements!!! Taking the Plenum off tomorrow as well and replacing the plugs under it and installing my first helicoil. I got a light now at the end of the tunnel.
