# OIL FILTER LEAK AT SUB ZERO TEMPERATURES

Under extreme cold start conditions, a high pressure surge of engine oil on start-up can cause bulging of the filter which could cause an oil leak at the oil filter seal. This condition can be corrected by installing a new oil pump cover assembly which contains revised oil filter by-pass and pressure regulator valves serviced under the following part numbers.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
