Ford specification ESE-M4G234-A1, to the cylinder blocks along the corners of the rear main bearing
cap joint area, and on the joint face approximately 13mm (1/2 inch) from the rear of the cylinder
blocks.
Cylinder Block Sealer Application
8. NOTE: New main bearing cap bolts must be used during assembly.
Verify that the lower rear main bearing insert is in place and install the rear main bearing cap and
snug the bolts.
9. NOTE: The rear main bearing cap MUST be aligned and installed properly to seal.
Misalignment will cause an oil leak.
Align the rear main bearing cap to block by moving the bearing cap fore or aft so the rear seal stop
(located approximately 1/2 inch inward in the rear oil seal bore) of the block and cap line up. This will
ensure the crankshaft rear oil seal (6701) will seat properly when installed in the bore.
10. Tighten the bolts evenly to 90-104 Nm (66-77 lb-ft).
