3. Remove the two remaining hex. flange screws
from the breather cover.
4. Pry under the protruding edge of the breather
cover with a screwdriver to break the RTV or
gasket seal. See Figure 9-29. Do not pry on the

resulting in leaks. Most engines use a formed
gasket rather than RTV sealant.

Remove Valve Covers
Three valve cover designs have been used. The
earliest type used a gasket and RTV sealant between
the cover and sealing surface of the cylinder head. The
second type had a black O-Ring installed in a groove
on the underside of the cover and may have metal
spacers in the bolt holes. The latest design uses a
brown O-Ring, and the bolt hole spacers are molded in
place.
1. Remove the four hex. flange screws securing
each valve cover. Note valve cover differences for
proper location in reassembly.
2. The O-Ring type covers should lift off without
prying. If loose spacers are present, save them.
With the gasket type, break the seal by carefully
prying under the edges of the cover.
