Supersession Statement
This PI was superseded to update Models, model years, and engines. Please discard all copies of PIP5095F
Condition / Concern
Some customers may complain of an SES light with mis re codes or possible oil or coolant leak.
Recommendations / Instructions
On inspection you may nd coolant or oil in a spark plug tube.
Determine if the oil or coolant is coming from the spark plug tube and not leaking into it from above.
If the Spark Plug Tube is leaking replace the Cylinder Head, spark plug and coil.
These leaks are caused by porous spots in the head created during manufacturing.
The spark plug tubes are permanently sealed into the head and are not replaceable.
If you replace a cylinder head for this concern, mark the faulty spark plug tube before sending the head in for
warranty or core so GM Engineering or the re-manufacturing facility will know where the concern was.
Warranty Information
For vehicles repaired under the Powertrain coverage, use the following labor operation. Reference the Applicable
Warranties section of Investigate Vehicle History (IVH) for coverage information.
