Are these engines suppose generally quite from cold start or do they tend to rattle for abit say for around 1 minute?it is the later evo type engine 3.2

 

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

 

VANOS is knackered.

 

a vanos on the 3.2 will rattle for a few seconds then shut up; that's perfectly normal

 

Mines rattled from startup and it was one of the shells spinning. It also made a knocking noise when held between 2k and 3k.

 

i have not heard the noise myself just asking for a mate who is thinking of buying one!this particular one the owner reckons it sounds tappety for around 1 min from cold!was not sure if it had vanos fitted

 

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 "

 

the 3.2 as TWO of em, and there known to fuck up alot,,, the sign of them going is the rattle on start up that people claim " is fine",,,, usually the sell who says it though yet aint had the rebuild of a vanos to confirm after rebuild it still rattles on start up,,,,, just cheeper to say " they do that

just like someone on here once said ERST engines can melt at the drop of a hat,,, thats also bollox

 

am i right in thinking that these has shims and not tappets?i

 

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.

solid lifters i thought on them but aint totally sure tbh

ps: not all cossies hunt on idle either,, nor should they have MOT failing emmisions and smokey turbos

 

Yes you're right there.

It's not actually part of the BMW service and goes missed alot.

 

ive just taped my headphones into a loop as the lead has a fault with it and only plays in one ear unless i tape it up in a loop,, now it works it both !!!

does that mean my headphones have a fault or does that mean they are "fine"

 

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.

 

Sorry Ginge, i will disagree with you completely, the Vanos WILL rattle for no more than 5 seconds on start up - its perfectly normal. Any more than that then i agree, its probably knack'd

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

i remember a bloke at work who had one saying that,much like it is on top of a service to adjust shims on vauxhalls!he said it costs a hell of alot of money to do the bmw ones

 

Vanos units are known to rattle on startup until oil pressure builds up.

 

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 ??

 

Yeah I wouldn't think it would be a good job to do, 24v's

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

 

its not ment to though is my point,, what do you think the "rattle" is ?? the vanos waking up witha little shake in the morning ??

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.
