Please discard PIP5191. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI. Condition/Concern A Customer may complain of a ticking noise on cold start after sitting more than 6 hours. The engine will usually start quiet, then make a ticking noise after a few seconds that lasts about 3 - 15 seconds and then go away for the rest of the day. Recommendation/Instructions We have identified a possible concern with the oil pump pick-up tube to block seal being compressed. When this occurs there is the potential to draw in air when first started before the pump picks up oil to seal the gap. If you encounter this concern, remove the oil pan and inspect the seal. Note: THIS CONCERN IS MORE PREVALENT ON 50,000 MILE OR HIGHER ENGINES 1 If this seal is compressed within the cutout of the pick-up tube, then replace the seal and reevaluate the concern. (See Pictures Below) This is an example of a new seal This is an example of a compressed (worn out) seal Warranty Information For vehicles repaired under warranty use: Labor Operation Description Labor Time 4065870 Oil Pan Replacement Use Published Labor Operation Time Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. 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. WE SUPPORT VOLUNTARY TECHNICIAN CERTIFICATION 2
