    E36 M3 EVOs - any specific issues

    hey guys

    due to the unfortunate demise of the loud, low and slow I have been left with a small void where a fun car would be.
    I have been considering a few different vehicles outside of the blue roundel but we wont talk about them right now, one of the cars being considered is a E36 M.
    I won't be purchasing a car straight away, I'm just gathering up info on potential candidates early so I am well clued up

    I know all about the E36s shenanigans when it comes to wiring, body, suspension etc but im not so sure about the M3 EVO engines (S50B32)
    I know they are known for spinning shells but is there anything else I need to look for same goes for the 6 speed gearboxes
    I will be avoiding the SMG boxes like the plague as I don't think my wallet could handle a pump failure or any other associated shenanigans it may come up with

    what are they like day to day, I'd like to think it will be a 2nd car and I'll use the derv dream machine for the work slog but that probably wont happen

    thanks in advance

    vanos issues are sticky solenoids / can get noisy / the cover bolts can shear and make a mess of the engine
    iv read they can spin shells but dont think its common
    the gear box can get clunky and there not cheap to replace 500-700

    is there any way of stopping the cover bolts from shearing?
    in the event of the gearbox failing, is it possible to fit the 5 speed from the 328/3.0 M3 along with the 3.0 prop shaft? or a miss match of 3.0 and 3.2 props?

    The 6speed gearboxes get notchy but don't break any more than any other.

    Only the Evo has a large case diff so only the Evo has the 6 bolt drive flange, so a bit of messing about to swap 5 speed for 6 speed OR have someone make a hybrid prop which would be less messing about Educated guess that propes are not intechangeable.

    the 3.0s have the 6 bolt input flange too but i would imagine there would be a difference in the length of the prop due to the 3.0 have the medium case LSD
    It was more of a curiosity as I had heard about the syncro issues on the 6 speed boxes and the associated costs that go with them and that the 5 speed boxes are worth about 50p at the moment
    thanks for the info

    A lot of bollox written about the EVO engine and gearbox being troublesome..... The engine "can" spin bearings if over revved a lot - but it's not exactly a common issue and easily prevented with ARP bolts and new shells - vanos issues are not often terminal, they are just noisy.... Easy to "service" the vanos unit with new seals, gaskets, filters and bolts.... 6 speed gearboxes are no more of an issue than any other, I changed the oil in mine with decent spec and it made the world of difference... Buy one with your head and ears NOT your heart...

    I have owned an EVO for two years, it has 109k on it with a full service history and still pulls like a train.... The vanos isn't exactly quiet, but doesn't cause any issues.... It's like every E36, most of them are 10+ years old with miles, they do need some attention.... I have really enjoyed owning mine for the last couple of years, I am only looking to sell mine because I have four other cars - not because there are any issues with it...

    Yep, Mate had 12 or 13 E36 M cars and only big expense was the usual SMG failure

    As above don't be scared of an evo with a noisey vanos, I've had
    Mine 5 1/2 years now at first the vanos was silent but now it realy loud but still putting good figures down on the rolling road.
    Arp con rod bolts are a defo as I had the bottom end go twice on me, which was partly bad look and a heavy foot.
