LIGHT TRUCK:
1984-95 BRONCO, ECONOLINE, F-150-350 SERIES
This TSB is being republished in its entirety to include the 1995 model year.
ISSUE: An engine knock of about 3-5 seconds may be heard on initial start-up, after an extended soak time (eight hours or more). This may be due to insufficient oil at the engine bearings, caused by engine oil drainback from the engine oil filter.
ACTION: Install an anti-drainback engine oil filter adapter. Refer to the following procedure for service details.
SERVICE PROCEDURE
1. Drain and discard engine oil.
2. Remove and discard engine oil filter.
3. Remove and discard engine oil filter adapter insert.
4. Install the service replacement anti-drainback engine oil filter adapter insert (E4TZ-6890-A).
5. Tighten the anti-drainback insert to 15-35 lb-ft (20-48 N-m).
6. Lightly lubricate the gasket surface of the new oil filter (FL-1A).
7. Install the new engine oil filter to the cylinder block and rotate the engine oil filter one-half turn after the gasket contacts the sealing surface.
8. Fill the engine with the proper grade and amount of engine oil, as specified in the appropriate Owner Guide.

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.ACTIONPrior 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): 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): 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.
