About the 1992–1997 Mercury Grand Marquis
The Mercury Grand Marquis of 1992-1997 is the aerodynamically restyled generation of Ford's rear-wheel-drive Panther platform, sold as a four-door pillared sedan in GS and LS trim. For 1992 it replaced the previous 5.0 liter (302 cubic inch) pushrod V8 with the 4.6 liter (281 cubic inch) modular SOHC V8 backed by a four-speed automatic overdrive transmission. It shared its chassis and drivetrain with the concurrently restyled Ford Crown Victoria, and the station wagon body (Colony Park) was dropped, leaving the sedan as the only body style.

I have been experiencing 2 problems on the car.
1) When engine is idling more than a few minutes I see a large puff of blue smoke when the engive is revved up
2) A pwersistant whining in the rear end is noticed. At 200,000 miles I had a mechanic check the rear differential and found it to be dry and about 1/2 inch of metal filings on the plug. Although I had paid for all the regular services to be done including the differential service it looks like it never was. Now the whining is persistant.
Can anyone provide advise?
Thanks
