FYI, most people don’t realize that a leak in the turbo is usually an installation/drainage or engine problem (such as excessive crankcase pressure) and not a problem with the turbo. Installation/Drainage: Oil passing through the turbo must flow to the engine by gravity. Thus, any restriction in the oil drain line will cause the oil level in the turbo bearing housing to rise above the oil seals and result in oil leakage into the housings. ***This is one of the main causes of a leaking turbo.
