A car is being given away by one of my dad's co-workers as he does not want to deal with the problem its engine is experiencing. Either cylinder 1 or 4 (far right looking down at the engine under the hood) has absolutely no compression. All other cylinders peak at a beautiful 150 pounds of compression. I have read a TSB about sticking rings in this engine, and supposedly the car was burning about a quart of oil every 1000 miles. Could I remedy this by using the method I've read about where the cylinder is filled with heavy weight oil through the spark plug hole and then cranked to "reseat and reseal" the rings? Secondly, other than a serious mechanical defect what causes absolute zero compression other than a ring problem.. As a side-note I would like to add that the radiator had been covered with cardboard in the winter as if the thermostat is possibly bad...maybe the car ran too rich and fuel-washed the cylinders? Please help! It's a FREE car!!! :( Or maybe it's not worth it..

Actually, it may be a bad coil pack. Both Cylinders 1 and 4 are on the same coil pack. What you may want to try first is to swap the coil pack for cylinders 4 and 1 with the coil pack for cylinders 2 and 3. See if that makes a difference. If it does, then the fix could be relatively cheap. You can get a pair of coil packs for roughly $80 (that's for all four cylinders).
If it doesn't fix your problem, then you've probably suffered some bad head damage, or have (costly to repair) valve damage. In which case, the repair would cost more than the value of your car.
Run your problem by the guys on the saturnfans.com forum. Some of them are "all knowing" of Saturn problems... they can help you more than I can.
Good luck to you.
P.S. I posted info on the coil packs on a previous answer. I'll leave a link in the source's section below:

Zero compression?
1) Broken connecting rod.
2) Stuck open exhaust valve.
2a)Stuck open intake valve
3) Hole in the piston.
