LEAK - OIL - 6.9L AND 7.3L DIESEL ENGINES AT REAR CORNERS OF INTAKE MANIFOLD

ENGINE - 6.9L AND 7.3L DIESEL ENGINES - NEW VALLEY PAN AND GASKET ASSEMBLY INSTALLATION PROCEDURE

LIGHT TRUCK: 1983-88 E-250/350, F-250/350

ISSUE: Oil seeping from the rear corners of the intake manifold may be caused by the valley pan and gasket assembly. The valley pan and gasket assembly has rear corner cutouts that eliminate the close metal to metal contact between cylinder block-to-intake manifold mating surface. The elimination of the metal to metal contact helps the RTV sealant to form a good bond for proper sealing. The new improved valley pan and gasket assembly was installed on all 7.3L diesels and 6.9L diesels after an engine serial number of 438225.

ACTION: To correct this, install a valley pan and gasket assembly using the following NEW installation procedure and the appropriate Light Truck Shop Manual, Volume B, Section 22-08.

1. Remove the intake manifold.

2. Remove the valley pan and gasket from the cylinder block.

3. Clean the RTV sealant and gasket material off the cylinder block and intake manifold mating surfaces. Use a suitable parts solvent cleaner,

6. Coat the bottom of the valley pan gasket at the water ports with Ford Gasket Eliminator (E1FZ- 19562-A) included in the kit, Figure 12.

NOTE: FOLLOW THE APPLICATION INSTRUCTIONS PACKAGED WITH THE FORD GASKET ELIMINATOR.

7. Place the new valley pan and gasket assembly on the cylinder block. Install the valley pan strap and four (4) bolts, Figure 13.

NOTE: DO NOT WIPE OFF EXCESS RTV SEALANT FROM THE VALLEY PAN AFTER INSTALLATION. ALLOW THE RTV SEALANT TO SEEP AT THE CYLINDER BLOCK MATING SURFACE.
