On this engine, there are certainly bent valves. At this point, it is
likely that replacing the bent
valves and seats with the proper machine work to ensure that they do not
leak would solve the
problem. Running the engine with bent valves can lead to severe damage to
the cylinder head,
and possibly even to pistons and the cylinder walls.
The suggestion of removing the camshafts to run a compression test would at
least avoid further
damage to the valve train. This approach would require using compressed
air (at very low
pressure) applied to the spark plug hole while checking the intake,
exhaust,
and oil filler for signs of leakage. This can bent/pinpoint leaky valves
and also detect blow-by
(leaky piston rings).
Due to the litigious nature of our society:
THIS PROCEDURE CAN BE DANGEROUS! DO THIS AT YOUR OWN RISK!
Application of air pressure WILL cause the engine to rotate. Excessive air
pressure can damage
the engine. If you stick your finger in your eye it will most likely hurt.
There may be other
hazards not mentioned here.
Note that clearances on the 8-valve engine allow the engine to rotate
without piston to valve
contact when the timing belt breaks.

If you have the know-how why not just try to install the new belt and see
what happens? You could be lucky. Justin
