|Elantra suddenly stopped
My 1995 Elantra suddenly stopped running,
and when the mechanic took off the upper
timing belt cover, we could see the timing
belt, but when the mechanic rotated the
crankshaft, the belt did not move. He found
the belt to be tight and not broken. Although
the timing belt does not seem to be broken,
could the pistons have hit the valves, causing
severe engine damage?
The timing belt has failed. What you are seeing
are the results of the teeth shearing off the inside
of the belt. The valves may or may not be bent.
You could try replacing the belt and doing a
If the compression check is okay, the valves are
not bent. If the compression is low in any cylinder, it is likely that the valve(s) of that particular
cylinder are bent. Personally, if I find that the
cogs on the belt have sheared or the belt has
snapped, I will immediately take off the head
because in such a case it is most likely that the
valves are bent.
