Just saw this on Powernation : Engine Power show today. It is a one piece seal, you make a single cut, place around crank, then install rear main seal retainer. The single cut goes into the retainer. Of course this requires installing with crank out of motor. This show was rebuilding a slant six. Very interesting and the show said the seal is offered at Fast Fish Auto Parts. Not a cheap seal, but they claim it cures common rear main seal leak. Anyone use this seal? Curious to results if you have used it.
