The Check Engine Light Was Blinking last night and it was tough climbing hills. Today running real rough. Dropped it off at a Ford dealer. They say they're going to have to tear the engine apart to find the problem. It has low compression.
What does this sound like? Anything else I could check?

Typically the cel blinks when too much raw fuel is entering the combustion chamber and not being burned. If too much fuel had got into the cylinders it may have washer down the cylinders causeing the low compression and rough running.

I would start by pulling codes. I would shoot a litttle oil into each cylinder and see if the compresion returns. Oil probably smells pretty gassy.
