We were told that our 2003 VW Jetta needs a whole new engine after the timing belt broke and all 16 valves were bent, is it possible to replace just the valves?
The mechanic who's looking at our car replaced the water pump and timing belt but then
said all 16 valves were bent when he opened up the head and that we'd need a new
engine. The car has 150,000 plus miles on it and we've only had it a year and a half. We
know very little about cars but its hard to believe a new engine is the only option.
Why were all the valves bent? Timing belt break? The reason the mechanic is suggesting another engine, is the cost of labor to rebuild the current engine will far exceed the cost of a used or remanufactured engine block.
Tom is correct. On some engines when the timing belt breaks or jumps the pistons actually slam into the valves as they are now opening at the wrong time during the piston's stroke. This is called an interference engine. If it were me, I wouldn't bother fixing it. I'd use the money for a down payment on something newer with less miles. But that's just me. HTH. -Jim
