Cleaning, Inspection, and Testing

Intake and Exhaust Manifolds

Intake and exhaust manifolds are one piece castings
and may be cleaned with steam or suitable noncaustic
solvents.
Clean contact areas of EGR O-ring in the intake
manifold, using Injector Sleeve Brush (Table 9). Make
sure carbon above and below contact areas can be
vacuumed from the intake manifold. Vacuum loose
carbon debris.
