    turbo oil pressure

    I have a GT4202 journal bearing turbo and ever since new I get oil in the outlet of the compressor.
    engine is a 1UZ running 10w40 synthetic oil and can have 100psi of pressure when cold.
    question is can I run a restrictor with a journal bearing turbo or could I try one of the new turbosmart turbo oil pressure regs?

    How big is the oil drain and where does it drain back to?
