what causes a Subaru B4 twinturbo engine develop oil problems in the turbo?
i want to purchase one but my friend's has developed such problems requiring engine overhaul. Is it a common problem. his has done 89000km and is regularly serviced.
Inexpensive turbochargers are not pressure lubricated to the turbocharger bearings by the oil pump. Even when they are a common problem Alignment, suspension . When you turn a hot engine off the turbocharger bearings get no oil pressure or oil circulation. A promlem called "oil coaking" takes place. The small amount of oil literaly bakes on the bearings because the hot cast iron side of the turbocharger soaks heat eventually causing failure. If he's determined to keep the car the bearings inside the turbo need to be replaced. His only saviour is switching to a full synthetic motor oil of the recommended viscosity. Synthetic oil has the ability to stand much higher temperature before flashing to fire.
