5kTQ squeal

[James Fawcett <jfawcett@mail.win.org>]

Alright, here is the question.  When I am in 3rd, sometimes it happens in
4th too,  and I am reaching 3000 rpm at any acceleration, it begins to
squeal a really high pitched squeal at about 2800 rpm until I shift or I
slow down to below 3000.  It doesn't do it all the time though, but
sometimes is enough.  The only thing I can think is maybe the rear
crankshaft seal.  I know there was some talk about this on the list before,
but I don't think the scenario was the same.  Any help would be
appreciated.  Thanks.
