DESCRIPTION & OPERATION
Some characteristics of the E-Tech™ cylinder
head are not visually evident, but are still
significant (Figure 44). They include the following
listed items:
r
Push rod holes are angled at four degrees
due to outboard location of camshaft.
r
Large nozzle sleeve diameter to
accommodate 22-mm nozzle holder
assembly.
r
Water-jacket casting designed to improve
coolant flow.
r
Lower exhaust stud holes intersect with
push rod holes; upper exhaust holes may
intersect as well. This requires that all
exhaust studs be sealed at installation to
prevent oil weepage.
E-Tech™ and E7 cylinder heads cannot be
interchanged because of the differences in the
machining.
