| Oldsmobile Engine >> MILKY DEPOSITS IN THE CRANKCASE
Milky Deposits In The Crankcase On
1988-91 GM 2.3L Engines
The AERA Technical Committee has been informed of a condition of milky deposits in the crankcase of 1988-91 GM 2.3L Engines. It is normal for moisture to accumulate in the engine's oil in cold weather which can cause milky deposits to form on internal engine surfaces visible on the oil dipstick. If these conditions persist, the engine oil and filter should be changed every 3000 miles or three months, whichever comes first.
This condition is most common in internal combustion engines and is more visible in the quad four engine, due to its cooler running and operating efficiency. VIN codes A & D, in the Oldsmobile Cutlass Calais have been directly affected.
