This is a common misperception, but, most of the time it has nothing to do with the turbocharger functionality. More than 95 percent of the time, oil leakage is caused by a few issues: Oil drain line that is too small ∙ Oil drain line restricting oil ∙ Excessive blow-by To determine if this is one of the reasons for the oil leakage, follow these steps: CHECK THE SIZE OF THE OIL DRAIN LINE. It should be equal to or larger than the bearing housing oil drain—and, the larger the oil drain, the better (within reason). CHECK TO SEE HOW THE OIL IS RETURNING BACK TO THE ENGINE. The oil drain line should be straight and downhill, with no level spots or upturns, to remain freeflowing with no restrictions. It’s important to avoid 90° bends, so the drain line can enter the oil pan above the static oil line and not in line with the throw of the crank. CHECK TO SEE IF THE ENGINE HAS EXCESS CRANKCASE PRESSURE/BLOW-BY. If the engine has high mileage and is in need of rebuilding, this can cause excessive blow-by. This essentially creates a higher pressure or restriction in the oil drain and does not promote good oil flow, causing the oil to follow the least path of resistance. If you follow these steps and determine it is not an improperly sized or restricted oil line, or excessive blow-by, then the leakage also may be due t excessive tilt of the turbocharger, a damag d bea ing system, or worn or collapsed piston rings.
