Crank Bearing

What is the estimated cost of replacing a crank bearing seal on a 1996 Plymouth Neon Expresso?

My 1996 Plymouth Neon Expresso has a slow oil leak that doesn't occur when the car is sitting still, the theory that it is because of a worn out crank bearing seal is the worst-case-senario. So if you know how much it may cost to replace (keeping in mind that to replace it means that the motor and the automatic transmission would have to be pulled to get to it) a crank bearing seal, please I'd like the "ball-park figure".

P.S. Dealer's won't give estimate before the car is brought in.
Besides the oil leak problem the car runs great, like a purring lion. No other problems.
The car is worth $3,000 in good condition, we bought it for under just $2,000 because it had recently been in an accident (no damage now to the car, it was well taken care of). As it is an Expresso (the rare sports edition of the Plymouth Neon) the worth of the car is higher than average 12-year-old Plymouth Neon or Dodge Neon.

Ball-park figure: more than the car is worth. A LOT more.

You are stuck with this problem, or you need to look into getting another used car -- something in the range of $2000 to $3000.

A 12-year old Neon with an oil leak is going to be worth $1000, tops.
