Ford Repair: oil leak, 1997 ford taurus, pan gasket

Question
1997 FORD TAURUS-I PUT A NEW RADIATOR IN-NOW WITH NEW ENGINE PRESURE I NOW HAVE A REAL BAD OIL LEAK-I THINK ITS THE FRONT OIL SEAL-MY QUESTION IS-CAN I FIX IT WITH THE ENGINE IN-AND IF THERES A CHANCE IT COULD BE TIMMING CHANGE COVER GASKET OR OIL PAN GASKET-I LOST 2 QUARTS OF OIL DRIVING LESS THEN 3 MILES-ITS A 3.0 ENGINE WITH AIR

Answer
Please do not drive the vehicle at all!If you are looking at a leaking front seal or T.C gasket it would be a good idea to replace the timing chain/belt and oil pan gasket at a minimum.Look at replacing the water pump if the mileage is above 65,000 miles while you are there.
