    Power valve,Repairs completed, tested O.K,

    Bryan----

    I DO NOT RECOMMEND "turning down" the spindles. This is an "ease of assembly/disassembly trick" that certain unsophisticated rebuilders have been using for years on 63-82 Corvette rear bearing assemblies to produce what is called a "slip-fit" unit.

    Unbeknown to many modern-day Corvette enthusiasts, most 63 Corvettes, the first to have the then-new independent rear suspension system, were delivered with "slip-fit" rear bearing assemblies. Because of problems with this design, many of these cars were retro-fitted under warranty with the "press-fit" design. This design was used on all 64-82 Corvettes.

    Going to the "press-fit" design certainly was expensive for GM, both in terms of the retro-fit and the complication for assembly which the press-fit design created for their sub-assembly operations. It also required dealers to acquire a bevy of new tools from Kent-Moore and complicated service operations. You don't suppose that GM did all this because the "slip-fit" design was just as good as the "press-fit" design, do you?

    Ref, Power valve post yesterday the 11th.

    67,L-71,4speed. Changed the power valve and gaskets. The old power valve was leaking by. I installed a new PV and she starts right up w/out black exhaust.

    I did the old on the spot vacuum test(mouth to valve) and the old #65 power valve wasn't moving. The new one pulled in and out. Thanks Clem as I said I haven't had a PV problem in years.grr#33570

      older PV get eaten up by the stuff in the newer gasolines. if you have a older PV i would replace it with a new one that has better material. octane bosters also are hard on them.
