| Cadillac Engine >> REVISED INTAKE MANIFOLD GASKET END SEALS |
Revised Intake Manifold Gasket End Seal On
GM 4.1, 4.5 & 4.9L (Cadillac) Engines
General Motors Corporation has revised the intake manifold end
gaskets for all of their aluminum V8 engines used in Cadillac
automobiles. The revised seal features reinforced flanges to
more positively retain the seal in position on the cylinder block
(Figure 1). A pair of end seals is available under GM Part
#3635212.
The revised seals can be used as is on all transverse application
but need to be slightly modified when used on longitudinal
engines. Material needs to be trimmed from the flanges to
accommodate the internal ribs in this block. Relieve the front
seal in two areas and the rear seal in one area (Figure 2). For
proper fit the seal should lay flat on the cylinder block.
