Volvo 460 Engine problems

Discussion in 'Volvo 460' started by Dianne Cornes, Feb 13, 2004.

  1. Hi
    I've got a 1992 Volvo 460 GLE injection (B20F) with a couple of engine
    problems. Firstly oil consumption is really high, from a full sump (max)
    after about 200 miles it's barely above the min mark. No leaks are apparent
    (I guess I would notice this loss of oil) and there's no blue smoke from the
    exhaust at cold.
    Secondly, its sometimes difficult to start; the engine turns over but it
    takes a while to fire, but as soon as it has fired it's fine. At other times
    it starts as soon as the key is flicked and this problem seems to be
    unrelated to the temp of the engine. Finally the engine pinks a little under
    load and I thought the knock sensor would advance the ignition timing to
    prevent this?
    The car's done ~100K
    Any ideas gratefully received.

    Right, your pinking is most likely due to the oil in the combustion chamber
    being burnt.- there were all sorts of problems with this engine when Volvo
    launched it in 92 with high oil consumption- they never really sorted it
    entirely and it cost them afair bit with engine rebuilds / replacements
    during warranty.

    Its basically a piston / oil ring / bore sealing problem and the fix is
    strip the motor, hone the block and fit the modded pistons and new style
    rings- not a cheap job.

    You wont see any blue oil smoke as the cat is doing a good job at burning

    You're best bet would be either change the car, or swap to a 1.8 MPI engine
