I have a 1982 Ford Escort (yes I know, a POS) with a 1.6 liter engine.
It has been sitting for about 6 months. What happended is the water pump decided to seize up (bad bearing I gather) and completely shredded the teeth on the timing belt. Needless to say I was very angry.
My friend and I managed to pull the old timing belt and the water pump out of the car. It is ready for a new pump and timing belt. My question is how should I check for valve damage? I really do not want to remove the head or the valve cover.
We have rotated both the crank and camshaft. (in the proper direction of course.) they both seemed to rotate freely and with out binding.
But I want to be sure the valves are OK.
By the way how do I go about putting the timing back together peice by piece, step by step?

The customary method would be a cylinder leakdown test.
Turn the crankshaft to TDC, turn the camshaft so the rotor is pointing to the terminal for #1 sparkplug, install cylinder leakdown tester in #1 sparkplug hole and take a reading.
Rotate the crankshaft 180 degrees, rotate the camshaft 90 degrees (in the normal direction of rotation) repeat cylinder leakdown test on cylinder #3.
Rotate the crankshaft 180 degrees, rotate the camshaft 90 degrees, repeat cylinder leakdown test on cylinder #4.
Rotate the crankshaft 180 degrees, rotate the camshaft 90 degrees, repeat cylinder leakdown test on cylinder #2.
You probably don't own a cylinder leakdown tester nor have access to the necessary compressed air needed to perform the test, it would probably be cheaper to just install the new
T-belt and waterpump, start the engine and see how it runs.
Or, you could take the vehicle to a professional who has the equipment and have them do the leakdown test.
The odds that a valve didn't bend when the T-belt went are
NOT in your favor.
Invest in the proper repair manual, that way you'll have the advantage of the graphics that show proper timing mark alignment and torque specs.

I installed the new water pump. I then set all four pistons to mid block and turned the camshaft 3 times. It turns freely and easyly so does mean I got lucky? the crank also turns easy as well. thanks.

Would it be better to take some pictures and sell the whole thing on ebay or should I attemp to fix it? I am not really attached to this car. If i want to fix it I would be out $29 bucks at the most. If it has valve damage then I guess I am SOL because i do not have $600 or more for a new head and what not...

Did it still run at all before you took it apart? If so, the belt might have just slipped a tooth

That just means nothing has broken off and jammed it. You still have two choices, put on the belt and see it runs, or have it tested to find out in advance if its going to run.
