Some customers driving a 1989 A car with a 2.8L engine (VIN Code W) may comment concerning poor oil economy and/or bluish colored smoke
coming from the tailpipe.
The cause of these comments may be the valve stem seals. To repair these conditions, complete the following:
1.
Check the engine serial number on the rectangular machined pad located on the left side of the engine.
If the engine serial number begins with an "A" and is between 90810 and 90922, then replace all valve stem seals with new seals. The new seals
