Are you *sure* that the turbo oil drain hose has not been compromized ion any
On most turbos, the oil seals are very simple devices, and depend more on
centrifigul force to spin the oil off the turbine shaft, rather than actually
ddoing any physical sealing.
Hence, the seals are very sensitive to any backpressure in the oil drain
If there is ANY restriction in the turbo oil drain line (or the drain line
has been replaced with a smaller tube) there is the possiblility that the oil
would rather go out through the exhaust then down the drain..
Conversly: If the oil isn't getting burnt in the cylinders, where else CAN it
get into the exhaust?
