CAUTION:
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:
To aid in assembly, apply petroleum jelly to the back of the crankshaft thrust washer.
NOTE:
The oil groove on the thrust washer must face toward the rear of the engine (crankshaft surface).
NOTE:
The jack screws are a part of the main bearing cap assembly, and are screwed into the main caps, not the cylinder block.
CAUTION:
Do not scratch the cylinder walls or crankshaft journals with the connecting rod.
NOTE:
Stages 8, 9 and 10 are for all eight connecting rods, rod caps and pistons. Only one connecting rod, rod cap and piston is shown.
CAUTION:
Do not scratch the cylinder walls or crankshaft journals with the connecting rod.
CAUTION:
The rod cap installation must keep the same orientation as marked during disassembly.
NOTE:
The connecting rod caps are of the cracked design and must mate with the connecting rod ends. Excessive bearing clearance can result if not mated correctly.
NOTE:
Main caps are not shown for clarity.
CAUTION:
Make sure all coolant residue and foreign material is cleaned from the block surface and cylinder bore.
NOTE:
RH is shown; LH is similar.
NOTE:
Do not turn the crankshaft until instructed to do so.
NOTE:
LH is shown; RH is similar.
NOTE:
LH shown; RH similar.
NOTE:
Lubricate the O-ring seal with clean engine oil.
NOTE:
LH is shown; RH is similar.
CAUTION:
Timing chain procedures must be followed exactly or damage to valves and pistons can result.
CAUTION:
Do not compress the ratchet assembly. This will damage the ratchet assembly.
NOTE:
If the engine front cover is not secured within four minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness or four minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
CAUTION:
Make sure the O-ring is in place and not damaged. A missing or damaged O-ring can cause foam in the lubrication system, low oil pressure and severe engine damage.
NOTE:
Clean and inspect the mating surfaces and install a new O-ring. Lubricate with clean engine oil meeting Ford specification.
NOTE:
If the oil pan is not secured within four minutes, the sealant must be removed and the sealing areas cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness or four minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.

CAUTION:
Do not rotate the water pump housing once the water pump has been positioned in the cylinder block. Damage to the O-ring seal can occur.
NOTE:
If not secured within four minutes, sealant must be removed and the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of wetness, or four minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
