  • Q:

    This to my understanding is a sleeve that fits over the crankshaft at the point where the seal comes in contact with the crank to create a new surface for the seal to ride on which should eliminate any leak that might be from wear on the crankshaft. My question is does this kit include the seal as some do for other vehicles? My thought is if you increase the diameter of the shaft with a sleeve shouldn't there be a matching seal that is over sized as well. Or is the increase so slight that the factory seal can compensate for the difference. I would like a professional maybe even a rep. from national to answer this .I don't won't to be the first to write a bad review on this innovative Idea .And considering the labor involved to get to this part on your car I really don't think any one want's to repair it twice if it fails. Looking forward to hearing a answer back. Thanks for your time

      I know when the Tire Town and Muffler used this repair sleeve and ran the motor the first time, the car poured oil from it immediately. When they took the trans out again, the repair sleeve was torn apart. They then replaced it with the Felpro version (not as wide of a band), which seemed to work better, as it did not pour out oil immediately. It started leaking soon afterwards within 1000 miles.

      I had suggested for the shop to fill the worn crank groove in with a liquid metal, as per the manufactures instructions also. They thought that was a stupid idea. This is probably why it is leaking again. They didnt follow the Manufacturers directions nor my suggestion.

      Happy to help you with your question Greg! For this type of part the sleeve would be a replacement for the original. You would take the original out completely and replace it with this one so no undersized seal would be necessary. For additional information please provide us with the symptoms of your vehicle, as well as the vehicle information.
