the engines should not rattle; the vanos is meant to be noisy for like a few seconds then shut up, but if it its noisy for like 1 minute then there might be something more sinister going on such as Vanos
what sort of noise is it? camshaft type noise or bottom end?
edit: The last evo i heard was noisy was purly down to the oil which was used; it was cheap nasty shit and hadnt been serviced for a while, a quick engine flush and correct decent oil and it was quite as a mouse

if it rattles for a few seconds on start up its a sign the vanos is about to die,,, it means its fucked but not totally yet,, then you will get the flat spot and then,,, well the bill for repair

people buying cars will belive the " it should rattle on start up then shut up after a few seconds" cause the noise goes,,,,,,,, just like when you melt a engine or it starts to smoke/knock its pants off you turn the engine off and start it again in the mornin just incase its fixed the issue,,, and if it done happen you put it down as a " close call"
vanos is fucked with a rattle,,,, thats what the rattle is telling you just its not totally fucked, its the vano's way of saying " get me looked at before i die and really fuck your pocket "

They shouldn't rattle but they are quite a noisey engine compared with say a 328i,lots of evo's have noisey vanos & they run perfectly well for years like that, its only when the power drops off you need to worry. Their are people out there now that will recondition the vanos units for less than half the price of a new unit from BMW. I have a bill from the previous owner of my M3 Evo for just over Ł2000 to renew the vanos at 70k miles .
Shells can spin & damage crank if you over rev engine the conrod bolts have a habit of stretching, lots people use ARP bolts.

I replaced the solenoids and O-Rings on my E36 Evo which is supposed to be one of the reasons they always go. When checked @ Bmw after this they said my vanos was working spot on and before hand they said it needed a new unit.

bollox mate,its on its way out no engine is designed to rattle at ANY point in there life,,, nobody who sells a car with a rattle will say " its fine at the moment but its gonna start getting worse then die"
people buying cars will belive the " it should rattle on start up then shut up after a few seconds" cause the noise goes,,,,,,,, just like when you melt a engine or it starts to smoke/knock its pants off you turn the engine off and start it again in the mornin just incase its fixed the issue,,, and if it done happen you put it down as a " close call"
vanos is fucked with a rattle,,,, thats what the rattle is telling you just its not totally fucked, its the vano's way of saying " get me looked at before i die and really fuck your pocket "

a bottom end rattle is different i agree, but a Vanos will rattle
i was given this information on very good authority from a BMW engineer
here's a few threads for you Ginge from other knowledgeable people, they say exactly what i'm saying

no the true fact is its a sign its on its way out, it may well work for years like it just like a worn wheel bearing you was advised about on the MOT that you dont hear when driving
but they should NOT rattle,, they never did from the factory and only seem to on most cars now and people say its fine as car do fine for years with the rattle
when i bought my bmw mine rattled for a few seconds on start up and was told the same,, my vanos now dont "kick in" even though the rattle is there for a few seconds like it used to be,,, its a vanos on its way out and on a car that COMMON for having vanos issues,,,, REALLY would you wanna risk it ??

It should be part of the Inspection 2 service, strange why it's not.
I've had a few E36 M3's, one 3.0 with high miles, one 3.2 Evo with 90k and a 3.2 Evo with 50k and huge BMW service history, the one with 50k span one of its shells

rattle on a engine, think about what is actually happening and not what you "think" has happened and fixed its self

As said valve clearances rarely get checked and do give a rattle and people putting 5-50 oil in doesn't help either, i.e. BMW. If it's a top end rattle it's less likely to be vanos related and it's easy to check where the noise is coming from, the vanos sounds more like popping/ball bearing noise.

Even though you pay BMW to check the clearances every inspection 2, it rarely happens! I made it clear I wanted mine checked and some results and data on the clearances. They are worried that u will be upset when u can't get your car back the same day I expect as they might have to order the new shims.
