The above owner has called attention to the fact that the spindle of the Butterfly valve in the exhaust pipe always commences to squeak shortly after oiling. We know that this happens on most of the cars, although this is the first time an owner has actually called attention to it. If any remedy for this should be discovered, will you kindly advise us.
