Default Did anyone here ever repair a timing belt break?

Just wondering because a lot of web sites out there say you would need a whole new engine, but from the looks of what happens, it seems you might get away with keeping the same block but just replacing the cylinders that got mashed and the heads and valve gear and cams. Anyone ever gone through this could tell us what happened?

it depends on the severity and conditions of the break.

If it broke during maint. work and you tried to start it, you'd probably just bend a few valves and not do much/any damage to the bottom end (one would hope) so valves+guides

but if it let go while the engine was running....there would be little chance the motor would be salvageable (in terms of rotating assembly).

I got scared for ya. I saw the question and who posted it and thought " oh man, he waited too long " You should do it soon seeing how it's almost at the recommended mileage. Why wait and have alot more worry and work later? I've heard minor damage stories but I've heard so many more major damage stories.

I am waiting to do my 96 first (early June, when the wife quits work and I can get her car for a few days).

Assuming that works out, I will do the 99 immediately afterward, when I can drive the 96 All will (supposedly) happen in June. Will remain nervously twitching until then....
