Why is my engine leaking around the front seal?

(1990 Buick LeSabre)
in New Castle, IN on July 16, 2014
I have a oil leak around my front seal. My mechanic put a new seal in and its still leaking a lot at between 1100 to 1500 RPMS. He said the crankshaft is floating up and down at about .025. The car runs fine. Does this sound right? Help!Thanks!

Any noise from engine? Oil light coming on at all while idling in gear?

No engine noise at all. No oil light either. Since i knew its been leaking I have been keeping an eye on the oil level. It leaks a lot. The engine runs smooth and quiet. Any ideas?

If the crankshaft was 'flopping' around that much... the engine would be knocking and loosing oil pressure with the oil light coming on!! As memory serves me, its the 3.8 L V/6 ... Right?

Yes.Its the 3.8 motor. I hate to give up on the car because its only got 100,000 on it. If what the mechanic told me is true, I would think the engine would be knocking. What do you think I should do?

Get another opinion!... This mechanic is mistaken!! I do believe......

OK. Im with you. This whole thing doesn't make any sense. I know another mechanic I can take it to. Thanks for your help!
