Terry asked about "anything new on the rear seal".
Christian Marx in Germany came up with a new design that adds a VITON seal to
the scroll function without the need to machine the crankshaft.
The VTR magazine had an extensive installation article on this new design with
pictures. This is from a 2010 issue. VERY comprehensive.
In Kas Kastner's newest book, there is a complete chapter on leaks in our four
cylinder engines. (Kas is offering the book. at the moment, free of shipping).
Kas discusses Chris' new design, including the availability of a new centering
tool that corrects an error in the factory centering tool dimensions.
