This PI was superseded to update model years. Please discard PIP5095A.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
Some customers may complain of an SES light with misfire codes or possible oil or coolant leak.
Recommendation/Instructions
On inspection you may find 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 remanufacturing facility will know where the concern was.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
