1991 Ford Festiva oil leak

Check you valve cover really good for cracks. I had a leak and I swore it was in that place to but it turned out to be that the back corner of the valve cover was cracked. Its a good place to start looking. And your tranny fluid should be mercron (most fords are) but festiva's a hardy cars and most automatic tranny fluid does the job. We've never had problems. And when you are looking under the hood I belive its a black dipstick twards the rear of the motor
