    Hi folks,
    I'm trying to determine the engine type I have.
    I was told I need a new catalytic converter, and can't afford to pay
    my shop 1200,00 canadian dollars.
    So I looked around and found some for way less. But, it seems I need
    to know the engine type I have before making the purchase.
    My car: 1996 850 GLE, Engine B5252S DOHC.
    Apparently, to buy just the right replacement I need to know whether
    my engine is 20 or 10 valve?
    Any ideas?
    Thanks for your help!

    In case you 2 are looking for cats, here are some that I am
    for 20 valve

    for 10 valve

    That engine code is for a 10valve engine.

    Unfortunately, the 2.5 10v uses a bespoke manifold / cat arrangment,
    specific to only this engine. The 20v versions dont fit.
