I have a 1990 Ford Mustang GT. he car has just over 48,000 miles and I am the original owner. ON a trip to my local Ford dealer, I learned the car was leaking oil. On my first visit they rplaced the gaskets on both valve covers, the oil pan and the rear diff. The car was still leaking. The next visit they tightened the valve covers and the car was still leaking. They put a dye in the car and on the next visit told me my oil pumpm was the problem so they fixed that. The car is still leaking. What's wrong with my car or better yet, why can't Ford figure this out?
