# OIL LEAK AT OIL PAN DRAIN PLUG V-8, V6, OHV L4 CARS & TRUCKS

#### Models Affected: 1986 and Past Model Cadillacs With 2.0, 2.8, 5.0 and 6.0 Liter (Vin Codes P,W, Y and 6)

An improved oil drain plug gakset p/n 14090908 is available to replace the copper drain plug gasket P/N 14079550. The new gasket is a steel washer with captures o-ring (viton).

The new o-ring/steel gasket is capable of sealing irregular surfaces with light torques while retaining the clamping load over time. Reuse of the o-ring/steel gasket does not lessen sealing or torque retention characteristics. Recommended torque for the o-ring/steel gasket is 12-20 ft. lb.s (16-27 N.m.) Excessively higher torques may cause deformation, splitting, or loss of sealing capabiity.

The use of this gasket is optional and at owner expense.

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.
