STANDARD PROCEDURE - Cylinder Head Oil Gallery Cup Plug Service: Notes
WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Determine which cup plug is leaking before performing this procedure. If necessary, perform an engine oil leak dye test.
Each cylinder head on a 2.7L engine has 6 external oil gallery cup plugs. It is not necessary to remove the original cup plug to install a new cup plug. The cup plug bore is deep enough to allow for two plugs. If it becomes necessary to service an oil gallery cup plug, perform the Repair Procedure .
NOTE:
Inspect the cup plug bore in question for the presence of two cup plugs. If the cup plug flange is just inside (1-2 mm) the chamfered edge of the bore two cup plugs are already in place and the cylinder head cannot be repaired.
