That whitish-grey film seen anywhere in the vicinity of an exhaust
component is a sure sign of an exhaust leak. Exhaust fumes are the only
thing that produce that color on an engine. Check carefully the areas
where the pipes connect to the engine and any slip or other joints in
the pipes. Welded spots are a good source for leaks. Don't give
unquestioned trust to stainless pipes either. Two failures recently,
one a crack at a weld "ring" joint (that pipe is in some farmers field
somewhere) and the other was two small holes, irregular in shape, half
the size of your pinky finger nail, in otherwise solid pipe. Looked
like a defect in the pipe.
If you buy one of those cardboard detectors don't forget to remove the
plastic cover. DUH.........Larry, remove the plastic..................
