850 T5 turbo removal

Discussion in 'Volvo 850' started by John Palkovic, Jan 1, 2004.

  1. How hard is it to pull the turbo on a 1995 850? It has the B5234T
    engine. The car has been using oil, about 1 qt/300 mi. I'm certain
    that oil is leaking into the compressor side of the turbo. I
    ascertained this by inspection yesterday. I pulled the pipe off
    between the turbo compressor outlet and the intercooler. There was oil
    all over the inside of the pipe, and it could be seen inside the
    compressor side of the turbo. It could be a plugged drain line, or bad
    seals requiring a rebuild, or ???. In any case, I need to further
    inspect and diagnose the problem. Thanks for any help you can provide.

    Check if your intercooler has the oil seep hole in the bottom of it. If it
    does and its not leaving a pool of oil on the floor when parked, then the
    turbo ISNT leaking into the compressor side.

    Could be into the exhaust side though, which is more common. If the cat is
    doing a good job, it will burn the oil so you wont get blue smoke trails

    To answer your question, changing the turbo is quite easy, but like the
    rear drive cars, nuts are often seized on the studs, so it's a good idea
    to heat the nuts up before attempting removal.

    Lots of oil can get into the turbo through the PCV system - the PCV hose
    connects to the plastic hose just before the inlet of the turbo. You
    may need to replace the oil trap if it's too clogged - it lives under
    the intake manifold. This is not too hard to replace, but the intake
    manifold needs to be removed to change it, so it's a long job.
