It is not possible to correct this with the engine and transmission in the 
car. The little bolts holding the aluminum housing to the block will not 
come out with the flywheel in place.

You can either pull the engine / transmission, or just pull the 
transmission. It is guaranteed to leak without the spring attached.

Here's how I did the last one:

1. Remove transmission
2. remove flywheel
3. Remove pan
4. remove main caps
5. Pry the crank down just a little bit -- that's all it will come down -- 
rods don't have to be disconnected from crank. Remember the two bolts 
through the front plate and into the front main cap.
6. Now you can get the whole thing loose and fix it

Sorry to be the bearer of bad tidings.
