    I had my timing belt and water pump replaced and 100 miles later two valves broke and ruined my engine. What caused this.

    Sorry to hear of this...

    Given it was only 320 miles (that's what you wrote in your other - deleted as duplicate - message... which was it?) after your timing belt change, chances are that the fault lies with the procedure used... There are many ways to mess up a timing belt system replacement... difficult to guess where this one went wrong - and yes, there's a small chance that your problem had nothing to do with the replacement, but... at 320 miles...

    Who did the work? I'd get them to buy you a rebuilt cylinder head and a new timing belt system...

    Good luck getting them to do anything about it!!!

    I would say while the cam was locked in place (#1 up and #3 exh valve opened) they may have moved the crank enough to cause impact on #3 exhaust valve and weakened it without bending it.
    Then, in time it could have broken at the stem area, dropped the vlave in the combustion chamber..

    notice how many have #3 exhaust valves break and drop awhile after the timing belt
