Remove the old gasket material from the intake connection and intake manifold cover sealing surface.
NOTE: On some engines, the inside of the air intake connection will have a protective coating. When cleaning
the intake connection do not damage this coating, as it protects the air intake connection from corrosion.
NOTE: It is not uncommon to have a layer of soot and carbon buildup on the intake connection inner surfaces. If
the intake connection is being removed as part of another repair, it is not necessary to remove this carbon buildup.
Clean the intake manifold cover and air intake connection with solvent. Dry with compressed air.
Clean the EGR differential pressure sensor flow ports with a pipe cleaner or similar device. Inspect the cross-drillings for soot blockage. If any of the EGR differential pressure sensor flow ports are blocked, be sure to clean the ports completely prior to installing the air intake connection.
Remove the pipe plugs to clean the EGR differential pressure sensor cross-drillings. After cleaning the cross-
drillings, install the pipe plugs. Use thread sealant to prevent any leaks.

Remove the tape or cloth from the intake manifold. Inspect the intake manifold cover, cold starting aid, and air intake connection sealing surfaces for cracks or other damage.
Replace any damaged components.
