I'm hoping to resolve some oil weepage on the rear of our '53 R51/3. The manual refers to the application of "jointing compound" to prevent oil passage between the pinion spline and the input coupler. What sealants work well here? Sounds like a good application for Hylomar.

This was originally developed by Rolls-Royce and is a good choice here, as it never fully hardens. Another choice is Permatex Ultra Blue (and black) which actually seals better when exposed to oil. Not as easy to clean off as Hylomar, but the leak is fixed. I used it on a cracked oilpan at the racetrack, applied to to leak from the outside, with a full sump.. the repair lasted for an entire season of racing....
