Speedi sleeve for front seal leak
 

My problem is with a 2002 Stratus sedan, 2.4l dohc, auto. I have a recurring (and worsening) leak from the front crank seal. I believe my problem to be wear on the surface of the crank from contact with the seal. I really do not want to pull the engine, once a few years ago was enough for a lifetime lol. I have read that a Speedi sleeve can be used to correct the problem, but I have no experience with them. And if it is a a worthwhile idea, what size would I need? I am used to V8 pickups, this is all black magic to me, so I appreciate any help you can offer.
