Bmw m57 oil cap noise

[gregh]

i thought i had an extreme amount of blowby when i opened my cap but it looks exactly about the same amount of smoke as you've got. makes me feel a little bit better!

Mine has the same noise, did you find out what the problem was?? I could use some help with mine. Thanks.

No pull the dipstick and see how much smoke is coming out there every single M 57 I've seen has this blow by and nobody can give me an answer on whether or not that's normal

It's the noise of the cams hitting the shims as it rotates...

That's normal it's the sound of the vacuum pompe

Hi Jonh, can you tell if you ever discovered what this noise was?

[FIFAHERO]
