Turbo Oil Leak
Compressing air creates large amounts of heat, therefore turbochargers have multiple oil and coolant passages running through them to lubricate and cool the moving parts in the turbo. Seals throughout the turbo keep these fluids from leaking into the air intake of the engine.
A properly installed turbo should NOT leak oil. There are, however, instances where oil leaks occur. Here are the most common causes, depending on the location of the leak.
LEAKAGE FROM COMPRESSOR AND TURBINE SEALS
– 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 the 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°.
LEAKAGE FROM COMPRESSOR SEAL
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.
LEAKAGE FROM TURBINE SEAL
– Collapsed turbine piston ring from excessive EGT’s.
– Turbo tilted back on its axis past recommended 15°
