    what are my chances??

    Ok, on Monday, my car would not start; sounded like it was just spinning and all of a sudden, it worked and ran fine all day. On tuesday, would not start. checked everything, and noticed the distributor was not turning. turns out the timing belt was missing a bunch of teeth. NOW i have it apart, waiting for the new belt to come in. I know this is an 'interference engine'; what are the chances I DIDNT bend the valves?? and how the hell did it run on monday??

      Also while you're doing the belt , you can take the head off and inspect.

        I would also recommend to take a look while you have everything apart. But, instead of buying a new head, valve springs and valves are pretty cheap.

          Head gasket $$$

          Problem is a head gasket is $50; the set is $150, on top of the $250 parts for the timing belt (belts, seals, gaskets, Wpump, etc). Anyway to inspect it while the head is on the engine, or can I pull the head without pulling the in/exh manifolds??


          Thanks, Ive done this before, but not on an interferance engine.

            Just put the new belt, pump, etc in if you have a problem then you will know when you start it.... If you end up needing to replace valves you need a new belt anyways...

              Your best bet would be to take the head off while you have everything apart.

                X2. You want to look at everything while the head is off. You can take the cam shaft out and all the valves should be in the closed positions. Take it up to a machine shop and tell them you want the head checked for bent valves. It shouldn't be too much. If you wanted to do it the poor mans way, pour water into the cylinder head intake and exhaust ports and see if any water leaks out between the valve and the head.

                  are you doing the work yourself? if so, i would just put the new timing belt on, making sure its timed right, then before you put it all back together, just pull all the plugs out and do a quick compression test... you need the belt anyway, and that'll tell you what's up without having to put it ALL back together also, i usually unplug the coil and/or distributor when i do a compression check to keep from having stray sparks all over the place... (that shit hurts if u get too close, lol)

                    thanks, I think I will wait and do the compression test. I did a little research (google ), and it seems it depends on the engine rpm when the belt breaks. my car wasnt running, just trying to start it...let you know what happens on Monday.. thanks again.
