318iS - Changing all engine hoses help.

[redrobbie]

Hi guys,

Im plannin on changing all the hoses that are attached to the engine since they're in a really bad state and the engines not sounding great because of them.
E.g There is one hose goin into the engine which comes off sumtime and makes the engine cut out when driving.

Im new to all this mechanical stuff and want to do it my self. This is my first task in gettin the iS back to its best.

Can anyone advise me on how to get these hoses, how many there should be (I Dont want to miss replacing any), how much should it cost and where should i go- Bmw dealers or any parts shop???

Any gd advice will be greatly appreciated. Plus anyone know any good handbooks on the iS. My haynes e30 book doesn't cover the m42.

CHEERS!

What sort of noise do u get and where exactly?
u need an E36 Haynes manual for a M42 engine.
Have a look on here;

It just sounds a bit choked at times even when idling.

if the pipes are that bad, then note which ones you need and then pop down to bmw dealer, the main inlet pipe from airbox is common problem, renewing that pipe alone will prob make the world of difference

hi,a i,ve got same problem.got new breather pipes from main dealer cost Ԛ£40.i still need 1 or 2 pipes i think.got the easy ones changed first but i think im going to have to take off inlet manifold to make it easier to fit others.

[redrobbie]

Thanks mate, ive been told to to take off the inlet manifold aswell by guys on the forum. They said you can also see the extent of pipes that need changing aswell as so you can fit the others.

Keep me posted if you can how your getting on baboon.

Yup... taking the inlet manifold off makes replacement so much easier.

Just replace ALL the air pipes then... will make a world of difference.

[redrobbie]

Geeman have you done this before? How much it cost ya for parts?

[Geeman]

Not very much at all.

It was the first job I did on the car!

Not remembering the exact figure, but defintely sub Ԛ£40.

[David318is]

I've replaced most of the numerous airpipes as they were found to be split and it would be much easier with the inlet manifold off. total cost is around Ԛ£35-40 ish.While the inlet manifold is split (don't forget a new gasket), remove the injectors and leave in thinners for a few hours to get rid of resin and gum deposits-I've been told doing this will greatly improve the idle. I'm doing mine in the next couple of days

[redrobbie]

Since that was the first job on your car, i guess it means i'm on the right path then !. Ԛ£-40 phew i thought it would cost more.

David, do you have the part numbers for the hoses. I dont know what they are and want to get the right hoses from the parts shop(probably be dealers).

What do you mean by "thinners", as in white spirit stuff!?

[David318is]

Don't think white spirit will do it .Proper thinners is nasty stuff and smells like pear drops. I think Hamerite do it or see if you can beg some from a bodyshop or garage

[redrobbie]

Sent the pm david.

You have to be careful when ordering the hoses. There are two types of Throttle bodies fitted to the 318iS - one has a round disc that fits on the bottom, and the other has a pancake type device that fits between the throttle body and inlet manifold. Both of these are used to heat the throttle body / manifold by using the coolant to circulate round the system.

I took mine out completely and bypassed that particular section as mine is a dedicated track car and didn't need this.

The air pipes shouldn't be affected, though if you're changing the water pipes while you're at it (it would make sense to do this) then bear this in mind when talking to the dealers.

A chassis number should sort this out though...

Thanks Giles, i'll have a look 2morow.
