Chrysler Repair: Dodge 2.7L intrepid engine seized, plug holes, combustion chamber

Question
I have a 2003 dodge intrepid (2.7L engine) that has a seized engine.  Something in the oil system caused all the oil to spill on the roadway and the engine seized at the next stop light 1/2 block from the spill and then would not turn over.  We placed it in neutral and roll it off the road. It was towed to a Dodge dealer who said they didn't do a major inspection but that an attempt at cranking the engine failed and they recommended an $8000 engine rebuild or buy a new car.  Neither option particularly feasible.  What is the best way to see if the engine can be "unseized" and saved?  Thanks.

Hi Alan,
The dealer could try turning engine backward by reverse wiring just the starter motor directly to the battery, after disconnecting the regular wires to the starter motor*. That would be easiest way to determine if it will unseize and should not take more than 15 minutes to do that test. It will just freeup for a moment then you have the possibility of putting oil in all the spark plug holes to lube the pistons, then determine where/why the oil spilled and correct that, then after the oil has a chance to sit in the combustion chamber and you have a full load of oil in the crankcase try the starter in both directions to see whether you can get it turn freely once again. Then put the spark plugs back in, reconnect the starter, and see how it runs. I would be interested to know why all the oil drained out.

*PS: The way to do this reverse cranking would be to disconnect the battery completely (both clamps). Then disconnect the fat red + lead at the starter solenoid as well. Then with the starter motor so-isolated from the rest of the vehicle in this manner use jumper cables to reverse wire the battery to the starter motor: battery + post to any point on the frame, - post to the starter solenoid point where you removed the big red wire. Then use a jumper from that attachment point to the solenoid coils activation wire (brown), momentarily, which would reverse torque the crankshaft and possibly free up the seize situation. It would be best to do this when you have put oil down the spark plug holes for the 6 cylinders.
Have you had a chance to determine why the oil blew out? Anyother progress?
