    Started up the car yesterday and there’s a noise which I haven’t noticed before which sounds like a single marble loose in the top half of the engine. The noise isn’t regular, so guessing it’s not tappets, any ideas where to start looking people? cheers

    When was the last time it was started up? Does it do it from cold?

    Last time I started it was yesterday and immediately switched it off when I heard the noise. I don’t use the car much, last time I used it was probably around 2 weeks ago, but it’s a lot colder at the moment too, but never noticed this noise before. It’s loud enough to hear it from inside the car.

    I seem to remember back in the day a dodgy vanos making that sound. My E60 M5 made a very similar sound when the vanos on one bank went wonky.

    Sounds simple but is there enough oil?

    the car was under warranty and I am going back probably 10 years now so just left it at the dealership. Something about vanos gearbox is in my memory.

    Anyway, hopefully just the low oil will be the cause and topping up will sort it

    Just topped up with oil and the noise seems to have disappeared now thank god, what bricking it for a while there, not sure what was causing the noise though, I didn’t think low engine oil would be enough to cause that kind of noise although the car has done 170k miles I guess

    Be worth checking for any oil leaks. Have you had the CCV replaced?

    I had a bit of work done on various hoses last year on the breather system due to oil leaks, oil leaks have stopped but oil loss is still an issue but I don’t appear to be leaving a blue smoke trail behind me. Would you be able to pinpoint the item on a realoem pic the item you’re referring to by any chance? Cheers

    If you done the breather system I am guessing referring to the same thing.

    I know they can leak from valve gasket as its common.

    I’ve replaced the gasket several times, I’m pretty sure my rocker cover is distorted and needs to be replaced as I keep getting burned oil smells inside the car

    They do suffer various oil leaks as im sure your aware.
    Most common are:
    • valve cover gasket
    • oil filter housing gasket
    • CCV & Pipework
    • Vanos oil feed pipe washers/pipe
    Even if there are no leaks they do have a thirst for oil and the m54 is well known for it.
    My daily driver is a 330i tourer. Ive had from around 60k miles, and its now on 216k miles. Its always used oil, and still does.
    Fantastic engines however.

    As for the noise could possibly have been the vanos, or possibly the chain. (Although hopefully not)
    Mine has lifter tick on a cold start for the first second or two has had for the last few years i just cant be bothered to remove the cams to replace the lifters.

    Hopefully yours is fine however.

    I agree the engine is very good, just a shame about the oil issues really, maybe when it gets a bit warmer I’ll start taking a more detailed look at it, just too cold to be bothered to spend much time on it at the moment tbh

    Does anyone know the correct oil grade for this engine? I’ve been using 5w40 but only because that’s what came up on ecp website when I last looked lol

    5w30 or 0w40. 5w40 is fine to use. Used it on my old 330 and using it on the 530.
