Caution: Do not install cup plugs in the block until the cleaning, inspection, and necessary repair procedures
are completed. This will prevent dirt from being trapped in the engine.
Use cup plug sealant, Part No. 3375068, to seal the outside diameter of the cup plugs.
Use cup plug driver, Part No. 3376818, to install the cup plug.
A cup plug driver handle, Part No. 3376795, is required.
Caution: The cup plug must not be installed more than 2.03 mm [0.080-inch] below the surface of the cylinder
block. The cup plug will interfere with the camshaft if installed deeper than the specification. If a service tool
is not available, install the cup plug (1) flush to 2.03 mm [0.080-inch] (2) below the surface of the cylinder block.
