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.
O-Ring Part Number 951 107 241 02.
