I definitely think 0w-40 is the best supplementary solution here...

I have the same noise in my e36 when it is a little low on oil. After a top off, it goes away. I would suggest checking the oil level and adding to the max line before ever even thinking about vanos or other mechanical repairs. I would guess this is the issue more often than not.

I fixed a customers E34 530i who had valve noise and everyone on the boards said to overfill the crankcase to stop the noise. I still don't see how that made sense since all the oil is pumped up to their anyways, just like it is here with VANOS. Proper weight of oil is probably the safest bet, and being topped up, that's just something that is expected. I always carry an extra quart of oil with me and check it every other time or so when I get gas.

I agree, but you can't assume anything is expected here as you really don't know what someonce else knows about cars. Just saying the noise on start up issue is more than likely an oil issue and not a vanos or mechanical issue.

Once in a blue moon mine still makes the rattling noise if it sits for a while, and I've been using 0w40 for as long as I can remember. It's just something I've gotten used to.

Nice signature, by the way. Dead pixels...:rofl:

:thumbup: I good a good laugh myself...and it's ironic how true it is.

sorry to sound thick!
but what is vanos, please?
