Revised Cylinder Head Gasket and Head Bolts for Ford 2.3L Engine

Oil leaks and broken cylinder head bolts may occur if the head bolts
are not properly tightened. The newest level of cylinder head gasket
and cylinder head bolts are recommended any time cylinder head service
is performed. The new cylinder head gasket and bolts require a
different service procedure for all 1992 and earlier 2.3L engines.

The new head gasket and bolts are uniquely different from the
production designed parts. Because of the difference, the new cylinder
head bolts are the only bolts that can be used with the new head
gasket. If a previous head gasket is to be used, or if head bolts are
not available for the new gasket, the previous head gasket and bolts
must be used.

Failure to properly torque the cylinder head gasket an
lead to an improper sealing surface, which can result in a leaking
condition and broken head bolts.

• With the cylinder block and head properly prepared, install the new
head gasket. The camshaft must be properly positioned to ensure proper
timing alignment.

• Install all 10 head bolts into the block, finger tight.

• Use the new “Torque Plus Angle” procedure as follows only for new head gasket and bolts.

• Tighten all 10 cylinder head bolts in sequence shown in service manual to 51 ft.lbs (70 Nm)

• Retighten all 10 head bolts in sequence to 51 ft.lbs. (70 Nm).

• Tighten all 10 head bolts in sequence and additional 90°-100°

Factors of Crankshaft Selection

From the high-performance powerplants propelling Top Fuel dragsters to the subdued engines found in family sedans and grocery getters, each crank must be tailored to, and appropriate for, its specific application.

We know a crankshaft plays a critical role in an engine’s performance, converting reciprocating motion into rotary motion while serving as the backbone of the entire system. It must be strong enough to withstand the continuous pounding of rods and pistons, yet possess enough elasticity to absorb vibrations and flex, albeit slightly, when needed.
