When replacing turbo chargers on 1986 models where the turbine bearings are worn, the turbo charger outer oil supply side O-Ring, located in the left side balance shaft cover, must also be replaced. Swelling of this O-Ring could seriously impair flow of oil to the turbo charger. It must also be replaced whenever the balance shaft cover is removed for other repairs.
