Thanks again....I ought to know real soon.

BTW-what is the best way to check if it is the exhaust cam ? Pull the cam cover? Try to turn the cam the other way?

Thanks to both of you for the info. Sounds like its worth getting dirty for.

Thanks for the reply. The car was apparently cruising down the street when it quit. I checked the belt and it was broken, but when I got round to checking further, the rear cam is seized for whatever reason, and before I get into pulling the plenum etc I am looking to find if anyone else has run int...

I haven't pulled the cover off the timing belt but the tension was still intact, so I assumed (rightly or wrongly) that the problem was the distributor. I will have to get someone to crank it over while I watch the belt for rotation. Is the shearing of teeth a common problem for motors with this mil...

The rotor on the distributor does not rotate when the motor is turning over. Would I be correct in assuming that the distributor shaft or parts thereof are scrooged? S...
