TSB 89-01-15 Pre-'87 4.9L Oil Pan Sealing

APPLICABILITY:
LIGHT-TRUCK:
1988-89 E & F-SERIES, BRONCO

ISSUE: Engine oil leaking from the oil pan after the one (1) piece oil pan gasket (included in E8TZ-6E078-C) has been replaced may be caused by not applying RTV sealer on the oil pan and engine block mating surface. The oil leak could be mistaken for a rear crankshaft oil seal leak.

ACTION: Apply RTV silicone sealer on the oil pan and engine block mating surface. Refer to the following procedure for RTV sealer application locations. Insert this information in your 1988 and 1989 Light Truck Shop Manual, Section 21-11 for future reference.

RTV SEALER APPLICATION PROCEDURE
1. Clean gasket residue from the oil pump, front engine cover, engine block, rear main bearing cap slot and oil pump inlet tube and screen.

NOTE: MAKE SURE THAT ALL THREADED HOLES USED FOR ATTACHING THE OIL PAN TO THE ENGINE BLOCK AND FRONT COVER ARE CLEAN.

2. Apply a pressure sensitive silicone based adhesive such as Dow, Loctite or equivalent on the engine block rails and front engine cover mating surface.
3. Apply sealant D6AZ-19562-AA on the parting line at the front of the engine block between the engine block and engine front cover as shown.
4. Apply sealant D6AZ-19562-AA into the bearing cap seal groove at the engine block junction as shown in Figure 1, View A.
5. Immediately install the oil pan gasket on the engine block mating surface.

NOTE: MAKE SURE THE OIL PAN GASKET IS TUCKED INTO THE REAR MAIN BEARING CAP SLOT.

6. Place the inlet tube and screen assembly in the oil pan.
7. Position the oil pan under the engine.
8. Install the inlet tube and screen assembly on the oil pump using a new gasket. Torque the two (2) bolts to 10-15 lb.ft. (14-20 N-m) and the one (1) nut to 22-32 lb.ft. (30-43 N-m).
9. Position the oil pan to the engine block and install reinforcement plates.
10. Install four (4) new attaching bolts, (390674-S100) in the positions shown. Tighten the four (4) bolts by hand.
11. Install the remaining new attaching bolts, (390674-S100) except the 3 on the arch below the crank. Torque the bolts simultaneously to 12-18 lb.ft. (16-24 N-m).

NOTE: SEALER D8AZ-19554-A CAN BE APPLIED TO THE BOLT THREADS TO IMPROVE SEALING IN EXPOSED AREAS OF THE OIL GALLERY.

12. Install the three (3) remaining new bolts, (390674-S100) on the arch below the crank. Torque the bolts to 12-18 lb.ft. (16-24 N-m).

ISSUE: Reports of premature engine failure suggest some overhauled, new and/or remanufactured engine oil Systems are not correctly primed prior to initial engine start-up, after being installed in the vehicle. This may cause oil starvation during initial engine start-up.

ACTION: Prior to starting a new, overhauled or remanufactured engine, the oil pump and oil system should be primed to eliminate the possibility of oil starvation at start-up. Refer to the following Service Information for details.

SERVICE INFORMATION: Regardless of engine design, it is extremely important that the engine oil pump is correctly primed, prior to initial engine start-up.

Overhead Cam Engines (OHC, including modular V8s): Overhead cam engines use a G-rotor pump design and is driven by the crankshaft. If the engine is overhauled, the oil pump (prior to assembly) should be fed oil through the oil pick-up passage, prior to installing the pick-up tube and screen assembly. This can usually be accomplished by rotating the oil pump while oil is being fed into the oil pump inlet. Once the oil pump is primed, the oil pump can then be installed onto the engine.Remanufactured engines are usually cold tested before leaving the plant. As a result, the oil pump should not have to be removed from the engine and primed. Overhead cam engines, whether overhauled or remanufactured, prior to starting the engine, ensure the engine crankcase is filled to specification with engine oil. Disable the fuel supply to the fuel injectors (disable inertia fuel shut-off switch) and crank the engine in fifteen (15) second increments, until the oil pump is primed. An oil pressure gauge can be used to assist in determining when oil pressure is obtained. NOTE: ENSURE THE INERTIA FUEL SHUT-OFF SWITCH IS RE-ENABLED PRIOR TO ATTEMPTING TO START ENGINE.

Overhead Valve Engines (OHV, including smallblock V8s): Overhead valve engines (push-rod type) use an oil pump driven by the camshaft via an intermediate shaft connected to the distributor or camshaft synchronizer assembly.Whether the engine is overhauled or remanufactured, the oil pump should be primed prior to starting the engine. If the engine is overhauled, ensure the crankcase is filled to specification with engine oil and using an engine oil pump priming tool kit, (commercially available) rotate oil pump until it is primed. An oil pressure gauge can be used to assist in determining when oil pressure is obtained.If a remanufactured engine is being installed, after the installation has been completed, ensure the crankcase is filled to specification with engine oil. Disable the fuel supply to the fuel injectors (disable inertia fuel shut-off switch) and crank the engine in (15) second increments, until the oil pump is primed. An oil pressure gauge can be used to assist in determining when oil pressure is obtained. NOTE ENSURE THE INERTIA FUEL SHUT-OFF SWITCH IS RE-ENABLED PRIOR TO ATTEMPTING TO START ENGINE.
