SERVICE INFORMATION
If a 1989-90 Sentra or Pulsar, equipped with the GA16i engine, exhibits a rattle or knocking noise from the timing chain system, use the following flow

When replacing the tensioner gasket, use only the appropriate Nissan gasket. Use of liquid gasket will block the tensioner oil feed hole,
causing timing chain noise.
