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.

Subject: ? Consequences of Broken Timing Belt (Diesel I4) ?

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
