NOTE:
During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, may cause engine failure.
NOTE:
Assembly of the engine requires various inspections/measurements of the engine components (engine block, crankshaft, connecting rods, pistons and piston rings). These inspections/measurements will aid in determining if the engine components will require replacement. For additional information, refer to

The rod cap installation must keep the same orientation as marked during disassembly or engine damage may occur.
NOTE:
Before assembling the cylinder block, all sealing surfaces must be free of chips, dirt, paint and foreign material. Also, make sure the coolant and oil passages are clear.
NOTE:
Do not install the upper thrust bearings until the crankshaft is installed.
NOTE:
Lubricate the thrust surfaces of the crankshaft with clean engine oil.
NOTE:
Make sure the side of the thrust washer, with the wide oil grooves, faces the crankshaft thrust surface.
NOTE:
Make sure the side of the thrust washer, with the wide oil grooves, faces the crankshaft thrust surface.
NOTE:
Make sure the side of the thrust washer, with the wide oil grooves, faces the crankshaft thrust surface.
NOTE:
To aid in assembly, apply petroleum jelly to the back of the crankshaft thrust washer.
NOTE:
While tightening the main bearing vertical bolts, push the crankshaft forward and the No. 4 main bearing cap rearward to seat the crankshaft thrust washers.
NOTE:
The rod cap installation must keep the same orientation as marked during disassembly or engine damage may occur.
NOTE:
Be sure not to scratch the cylinder wall or crankshaft journal with the connecting rod. Push the piston down until the connecting rod bearing seats on the crankshaft journal.
NOTE:
The next 3 steps are for all 6 connecting rods, rod caps and pistons. Only 1 connecting rod, rod cap and piston is shown in illustration.
NOTE:
Lubricate the pistons, piston rings, connecting rod bearings and the entire cylinder bores with clean engine oil.
NOTE:
Make sure the piston rings are positioned to specifications for installation. For additional information, refer to
- PISTON
.
NOTE:
If the piston and or connecting rod are being installed new, the piston rod orientation marks and the arrow on the top of the dome of the piston should be facing toward the front of the engine block.
NOTE:
If the piston and connecting rod are to be reinstalled, they must be installed in the same orientation as disassembled.
NOTE:
The rod cap installation must keep the same orientation as marked during disassembly or engine damage may occur.
NOTE:
After installation of each piston, connecting rod, rod cap and bolts, rotate the crankshaft to verify smooth operation.
NOTE:
Failure to use Motorcraft® High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.
NOTE:
The crankshaft rear seal retainer must be installed and the bolts tightened within 4 minutes of sealant application.

NOTE:
Coat the camshafts with clean engine oil prior to installation.
NOTE:
Cylinder head camshaft bearing caps are numbered to verify that they are assembled in their original positions.
NOTE:
If any components are installed new, the engine valve clearance must be checked/adjusted or engine damage may occur.
NOTE:
Use a camshaft sprocket bolt to turn the camshafts.
NOTE:
Use a camshaft sprocket bolt to turn the camshafts.
NOTE:
Use a camshaft sprocket bolt to turn the camshafts.
NOTE:
The crankshaft sprocket timing mark should be between the 2 colored links.
NOTE:
It may be necessary to rotate the crankshaft slightly to remove slack from the timing chain and install the tensioner.

NOTE:
During removal, the O-ring seal may remain on the cylinder head. If so, remove the O-ring seal from the cylinder head, inspect the seal (replace as necessary) and install the O-ring seal on the VCT housing.
NOTE:
Make sure the dowels on the Variable Camshaft Timing (VCT) housing are fully engaged in the cylinder head prior to tightening the bolts. Failure to follow this process will result in severe engine damage.
NOTE:
Make sure the dowels on the Variable Camshaft Timing (VCT) housing are fully engaged in the cylinder head prior to tightening the bolts. Failure to follow this process will result in severe engine damage.
NOTE:
Failure to use Motorcraft® High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.
NOTE:
The engine front cover and bolts 17, 18, 19 and 20 must be installed within 4 minutes of the initial sealant application. The remainder of the engine front cover bolts and the engine mount bracket bolts must be installed and tightened within 35 minutes of the initial sealant application. If the time limits are exceeded, the sealant must be removed, the sealing area cleaned and sealant reapplied. To clean the sealing area, use silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage.
NOTE:
Make sure the 2 locating dowel pins are seated correctly in the cylinder block.
NOTE:
Do not tighten the bolts at this time.
NOTE:
Do not expose the Motorcraft® High Performance Engine RTV Silicone to engine oil for at least 90 minutes after installing the engine front cover. Failure to follow this instruction may cause oil leakage.
NOTE:
The thread sealer on the engine mount studs (including new engine mount studs if applicable) must be cleaned off with a wire brush and new Threadlock and Sealer applied prior to installing the engine mount studs. Failure to follow this procedure may result in damage to the engine mount studs or engine.
NOTE:
Apply clean engine oil to the crankshaft front seal bore in the engine front cover.
NOTE:
Lubricate the outside diameter sealing surfaces with clean engine oil.
NOTE:
Installation of new seals is only required if damaged seals were removed during disassembly of the engine.
NOTE:

NOTE:
Failure to use Motorcraft® High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.
NOTE:
If the valve cover is not installed and the fasteners tightened within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage.

NOTE:
Apply thread sealant with PTFE to the Engine Oil Pressure (EOP) switch threads.
NOTE:
If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.
NOTE:
Use O-ring seals that are made of special fuel-resistant material. The use of ordinary O-rings may cause the fuel system to leak. Do not reuse the O-ring seals.
NOTE:
The upper and lower O-ring seals are not interchangeable.
NOTE:
Align the bracket with the index mark made during removal.
NOTE:
Failure to tighten the exhaust manifold nuts to specification a second time will cause the exhaust manifold to develop an exhaust leak.
NOTE:
If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.
NOTE:
Lubricate the seal lips and bore with clean engine oil prior to installation.
NOTE:
One of the 8 flexplate holes are offset so the flexplate can only be installed in one position.
