First engine pull

Hi Guys

Well, I got around to pulling the engine out of a 75 bug given to us
last month -- was waiting for a nice day and yesterday was it. Amazing
how easy that is! The hardest part is documenting the connections (it
is a FI model).
Jan Anderson's trick of sliding the engine out the side seems so much
easier than out the back -- it worked great so thanks again. I also
noticed that the engine's top driver's side bolt is easier to get to by
taking the left rear tire off. I could actually see the bolt this way -
I had a hard time finding it, laying under the car.

I'd like to open the case and inspect it, replace bearings, etc.

I did notice some what-looks-like engine oil on the clutch plate, so
this is probably due to a bad engine seal behind the clutch plate,
right? What is a good way to make sure the case is not cracked? Also if
(hopefully not 'when') the case needs to be line bored, where (near CT)
would I get this done?
There's a fair amount of rust on the tins and fan shroud. I've noticed
some relatively inexpensive replacement parts -- are these advisable or
should I clean and reuse the originals?
This one is a FI model. Is there a way to test this engine outside of
the car once I get it all back together?

Lotsa questions - the first of many, I am sure.

Thanks!
Remco
