    Timing belts ware out.I have had timing belts jump on a diff brand of car and was able to replace belt and tensioner and car ran fine.But have also seen one that jumped and bent push rods and valves.So u could have bent some valves and damaged the pistons.You may want to take to independent shop get a second opinion

    This is one of those " you can't win for trying " questions.

    1. Rather than spending $ 5000.00 to fix an " old " engine,,,find out how much a used engine with less miles cost,,,and how much does a " new " engine cost ?

    Explanation for answer # 1.

    Although the engine is not actually old, The $ 5000.00 is only an estimate,,and the actual repair could be much higher,,it usually is.

    Lets say this was my car,,I would spend the least amount of money possible,,then sell or trade the car for a vehicle that uses a timing chain,,instead of a timing belt.

    The reasons manufacturers use a belt,,in my opinion is,,,,

    A. They know that a belt can break and when it does, they can charge you the cost of a new engine. ( conspiracy theory )

    B. A chain cost more than a belt so they use a belt and still charge the customer a premium rate for the vehicle and on top of that you need to get the belt changed about every 100,000 miles or so and this is a guaranteed dealership shop visit, so they not only get an arm and a leg for that visit but it gives them an opportunity to try and upsell the customer all sorts of other generally unneeded goods and services masqueraded as " recommended services " and then some poor unsuspecting schmuck gets taken to the cleaners. ( 2nd conspiracy theory )

    How exactly do they know it has valve and cylinder damage? Has the head been taken off yet? or has the cylinder been inspected with a "snake light"?

    If not either, then they are GUESSING.

    Whether to repair or not would depend entirely on the overall condition of the rest of the car. If it's tired, dented, interior worn out, needs tires, etc., then just write it off. If it's a nice car and has been trouble free for you, I think a used motor is a good way to go. Why put a new motor in a car with every other part being old?

    As for "why", the advice of 105K is obviously statistical. It's an estimate of when to do the job. Probably a good estimate for 99% of the time, but alas, not good enough for your car. Not your fault, just bad luck.
