We have the same car, i would have a mechanic check the ECU. thats the first step in finding out what is wrong and why its burning so mutch fuel. it could also be your air filter, but then agian, you wouldnt be burning a tank of gas a day. well hope you get it fixed.

There is a speed sensor on the rear diff cover that may me shot, however it is regulated by hertz so the dealer is the best place to see if the wires are okay. That sensor can be costly.

Oil pan gasket on 740 gle station wagon.


Hmmm...I don't think the clearance on your16v engine are that much different than the 8 valve models. On them, all you do is loosen the passenger side engine mount and jack the motor up. Be sure to use a block of wood so you don't bend anything. If you have access to a hoist or can build a support to use a come-along to winch it up it makes things much easier. If fo some reason one does have to loosen the steering yoke, the couplers are down where it attaches to the cross member. There is a pinch bolt you loosen and then it will slide.
If you're losing enough oil in 45 minutes that the oil light comes on or the engine begins rattling, you have more to contend with than an oil pan gasket. OP gaskets drip, not pour. I've installed a pan w/ no gasket and not had the severity of oil loss you describe.

Hi,
May I suggest a locking gas cap. You could put a large piece of cardboard under your car and if there are any drops the next morning that smell like gasoline you might find the leak if there is one.
Cheers,
Ken

On the 92, the belt closest to the engine goes around the power steering pump, water pump, and crankshaft pulley.

The second belt goes around the alternator and the crankshaft pulley.

The third belt goes around the a/c and crankshaft pulley.
