I've got a 1979 Chrysler Newport (we're talking Detroit coffin here...) in
beautiful condition...I just took ownership, and the fellow at the garage was
quite impressed with the shape it is in.  A minor point, though, has been
bothering me...there's a very faint hissing sound coming from somewhere in
the dash, on the driver's side.  I haven't been able to localize it, but
here's a bit of what I've found out about it:  the sound quietens under
acceleration, almost dying when you tromp on the accelerator; it also disappears
when you hit the brakes (regardless of pressure).  This second part sounds like
something to do with the brakes, but they're doing fine:  passed the safety
inspection and a 300-mile trip with nonstop traffic jam last night with no
troubles.  The hissing fades slowly when the engine is turned off.
	Equipment:  360 cid V8, `lean-burn' engine
		    ps,pb
		    automatic
The sound doesn't seem to affect performance nor handling nor braking, and if
I turn up the stereo, it even goes away :-)...but I'm still curious...

	I never did learn to let well alone...
