Hello.  I have a 1991 Ford Thunderbird with a rebuilt engine and
transmission.  One day as I was driving it, I noticed that as the car
was sputtering when I would hit the gas pedal.  I wasnt sure what this
ment.  I was just out to get gas.  The sputtering was occuring before
and after i got the gas.  The sputtering went on and off on my way
home.  I parked the car in my driveway to let it cool down (perhaps I
overheated it).  About an hour later, I wanted to take it around the
block just to make sure it was okay.  When I tried to start it, there
was no crank.  It sounded like metal on metal.  It was very loud and I
was very worried because I thought this car had reached its end.  The
next day I brought my car over to my mechanic(who is very good but
lately has dissapointed me) and he told me that the engine block had
cracked.  However, NOTHING leaked from under the car in my driveway.  I
had thought that when  and engine block crackes, all of the oil come
out of the bottom of the car.  This did not happen.  Can anyone tell me
if my mechanic is right and what I should do.  Also, I took a look
under the Hood and noticed no cracks.
