I've seen the valves get pushed through the head hard enough to break the
cam bearing caps.

Yes, the diesel is an interference engine.  In the belt breaks, the pistons
will hit the valves.  In our experience, this bends the valves, but does not
damage the head.

THe subject says it all- what are the potential consequences of a busted
timing belt in a diesel I4 engine? Are the valves interfering?  If so,
what is the availability of a new or re-man'ed head? Would one expect to
be able to rebuild a head if the valves got smacked?

This is from an older diesel jetta- so i guess that is the smaller I4.

I may be in the market for new (to me) engine if that will be a cheaper
route.

Thanks
