ENGINE NOISE DIPSTICK/CRANK INFORMATION

Model and Year 1984 CORVETTE

Certain early production 1984 Corvettes have had the dipstick interfering with the crankshaft during rotation causing an engine noise.

The reason for the interference was misdirection of the portion of the dipstick that extends from the bottom of the dipstick tube into the oil pan cavity.

The condition was corrected on July 20, 1983 by rotating the dipstick such that the rough edges are on the inside of the installed bend (reducing insertion force), and extending the lower portion of the tube approximately 1". If the interference condition occurs, replace both the dipstick and the tube. Make certain to apply sealer (P/N 9985345) to the portion of the tube that is inserted into the block.

Oil level gage tube is P/N 14081026 and the oil level gage is P/N 14060661.

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.
