torque the breather bolts down 10-12 ft.-lbs. If a gap of more than
the thickness of a rubber coated washer is present, determine
how much and select the appropriate number of rubber coated
washers needed to take up the gap.
11. If more than one rubber coated washer is needed between the
head and backplate, back out the breather bolts and install the
correct number of rubber coated washers.
12. Thread the breather bolts in and finish torque breather bolts to
