    Do a compression check, but there is unfortunately a good chance of valve damage.
    How many miles on the belt?

        I would say about 99.99% you have at least 2 bent valves if not more.......
        Probably the longet S2 project in history EVER!

            Not good,i feel for you but look on the bright side,i doubt it's as bad as mine were when the crank sprocket went for a poo:

            I bent 10,i was just about to dust someone in 3rd gear at about 4k rpm,they were so badly bent that the car wouldn't turn over,in fact i had to carefully knock them straight(er) before i could get the valve spring compressor to work and get them out
            Just make sure you replace the crank sprocket aswell as the belt/tensioner
            Good luck sorting it out
            It's a love/hate relationship with the S2,i love it,it hates me

              .



              My guess is the belt has not snapped but the crankshaft sprocket woodruf key has failed and upset the timing.

              Dont really hear of many belts snapping?

              Hope all goes well.

                  the S2 I had came with a snapped crank sprocket, took the head off. And there was no damage at all. Also know a guy that had the same with a 7A and also had zero damage

                  Hopefully you'll be as lucky

                          .

                          So did the belt snap and have you checked the crankshaft pulley?

                          Good job with the speedy repair.
