A properly installed turbo should NOT leak oil. There are, however, instances where turbo oil leaks occur.
Here are the most common causes, depending on the location of the leak.
– Excessively high oil pressure
– Inadequate drain – drain is too small, does not go continuously downhill, or the location of the drain inside the oil pan is located in a section that has oil slung from the crank causing oil to back up in drain tube. Always place oil drain into oil pan in a location that oil from crank is blocked by windage tray.
– Improper venting of crankcase pressure.
– Excessive crankcase pressure.
– Oil drain rotated past the recommended 35°.
Excessive pressure across the compressor housing inlet caused by:
– Air filter is too small.
– Charge air tubing too small or has too many bends between the air filter and compressor housing.
– Clogged air filter.
– Collapsed turbine piston ring from excessive EGT’s.
– Turbo tilted back on its axis past recommended 15°
More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.
