Oil Pan gasket leaks can only be fixed by using the 1993 level oil pan and pan gasket. When replacing the oil pan gasket, the engine assembly MUST be removed from the vehicle.
Replace existing oil pan and oil pan gasket with improved (1993 level) parts. Refer to the following procedure for service details.
OIL PAN - REMOVAL
Drain oil and coolant from engine.
Remove the engine assembly.
ENGINE ASSEMBLY MUST BE REMOVED BEFORE REMOVING THE OIL PAN. REFER TO SECTION 03 OF MUSTANG CAR SERVICE MANUAL FOR SERVICE DETAILS.
Mount the engine upright on a suitable engine stand.
DO NOT ROTATE ENGINE UPSIDE DOWN ON THE STAND OR SEDIMENT MAY FALL BACK INTO ENGINE.
Remove the oil pan retaining bolts and remove and discard the oil pan.
Rotate engine upside down on stand so the oil pan gasket sealing surface is facing up.
Remove any residual gasket material and throughly clean all sealing surfaces. Refer to Figure 1.
Figure 1 - Article 93-17-6
Wipe oil pan rails of new oil pan with cleaning solvent to remove any oil film. Refer to Figure 1.
Apply silicone sealer (F1AZ-19562-A) in six places as shown in Figure 2.
Figure 2 - Article 93-17-6
Install a new oil pan gasket (F3ZZ-6710-A) to the oil pan and position the oil pan to the engine so the transmission mounting face of the oil pan is aligned with and square to the engine block rear face.
DO NOT ALLOW THE SEALER TO AGE MORE THAN (2) MINUTES PRIOR TO OIL PAN INSTALLATION OR TOTAL (5) MINUTES BEFORE BOLTS ARE TIGHTENED TO SPECIFICATION.
Install and tighten the oil pan retaining bolts to 10-13.5 N-m (90-120 Lb-In).
THE TRANSMISSION BOLTS TO THE ENGINE AND TO THE OIL PAN. YOU MUST REINSTALL TRANSMISSION-TO-OIL PAN SPACERS IF THEY WERE ORIGINALLY INCLUDED WITH THE ENGINE ASSEMBLY. SOME ENGINES DO NOT REQUIRE SPACERS, BUT IF SPACERS ARE NEEDED, IT IS IMPORTANT TO MEASURE THE GAP BETWEEN THE REAR FACE OF THE OIL PAN (AT SPACER LOCATIONS) AND THE REAR FACE OF THE ENGINE BLOCK. REFER TO THE FOLLOWING PROCEDURE TO DETERMINE IF SPACERS ARE REQUIRED AND TO DETERMINE THE CORRECT SPACER.
With the oil pan installed on the engine, position a straight edge flat on the rear of the engine block so that it extends over one of the oil pan/transmission bolt mounting pads.
Measure the gap between the mounting pad and the straight edge using a feeler gauge. Repeat the procedure for the other mounting pad. Select spacers of the required thickness from the chart.

FAILURE TO MEASURE THE REQUIRED SPACE THICKNESS CAN RESULT IN INSUFFICIENT OR EXCESSIVE CLEARANCE BETWEEN THE ENGINE OIL PAN AND TRANSMISSION, WHEN INSTALLED ON THE VEHICLE, RESULTING IN OIL PAN DAMAGE AND/OR AN OIL LEAK.
Install the selected oil pan spacers to the pan mounting pads before bolting the engine and transmission together.
Tighten oil pan-to-transmission bolts to 40-50 N-m (30-39 Lb-Ft). Refer to Figure 2.
Replace oil filter with new filter.
Reinstall engine assembly. Refer to section 03-01A of the Mustang Sevice Manual for details.
