Devil foam on bonnet underside?

[benbenben]

This foam is driving me mad! Falling to pieces all over the engine and all over my clothes.

Going to rip it out, is it just for sound dampening?

Anyone suggest a replacement?

I'm running an 318i M10, so noise isn't really an issue.

[ross_jsy]

You can buy it new from BMW and it's relatively cheap

[jimbom30cab]

i know it falls off in chunks but is't removing it completely supposed to be a pig of a job ?

[sunnyr83]

Bonnet off job for best result and some sort of glue removal, i think reanult brake cleaner or something, may be very wrong there.

[bss325i]

From my sport thread.

Another job i have tackled recently is the under bonnet foam which is a common E30 problem and can be very unsightly under the bonnet when its old and crumbly!

A top tip for this job!

I have heard of other people tackeling this and it being very messy and time consuming. Well i have found something that speeds things up and reduces the mess!

Toytas own brand brake cleaner! It is solvent based and after removing the bonet, pulling of the bigger chunks of foam you are lift with the glue still on the bonnet with a thin layer of foam.
The Toyota brake cleaner disolves the glue and foam and turns it into a mush that can be scraped of, near enough wiped off with plastic filler spreader and a rag.

Once the mush is removed a wipe down with the brake cleaner and the surface is ready to stick the new foams on. The brake cleaner does not damage the paint in any way either.





Much better!

all i did- lay a blanket over the bay, a little plastic scraper took about 5 minutes to get 90% of it off (not scratching through the bottom later- some bits of that just pulled off by hand to bare metal) and only a bit of residue was left

which you would remove with the stuff above, but i got the whole bonnet re painted both sides

new stuff about £40 i believe, on my list of bits to get

Barry, what's with the two washer nozzle valves in your pics? Isn't there only supposed to be one?

Dual wash wipe system. One for normal one for intensive.

Cars with head lamp wash wipe also have intensive wash so two pipes and there for two one way valve run to the bonnet washer jets. One from the main tank and one from the smaller intensive wash tank.

BMW also sell screen wash which is clear/blue in colour and intensive wash which is green and should be used neat.

[polsta]

didnt know that !! is it possible/easy to fit the intensive system just for the screen without the HLWW ?

I was thinking ofbuying some of this to do my bonnet.
Opinions?

[ross_jsy]

I would just buy the foam from BMW, it's already cut to shape and looks good

[Idol]

Isn't the M3 sound proofing the same price and better upgrade? Can't think what it looks like, but remember its nicer?

[harry_p]

m3 insulation is a single moulded piece, and is NLA, and are very expensive when they do appear.

[polsta]

has anyone got the part number for the foam

is it this ?

04 Sound insulation set 1 51481925437 $73.63

on real oem, when clicking on a 325i , it doesnt list the deadening , but it comes up for 318is as that above ?

[polsta]

There are 2 different sets there, up to and after 89, plus the one I posted above as on a 91 is , so that's 3 different part numbers

anyone any idea why or if all 3 are the same or different ?

[polsta]

anyone ? not sure what part number to order

[Budgie325]

I hoovered mine off. Literally dusted all away. I still need to get some glue remover out to get the residue off and then i'll replace it with the stuff above. Did notice this on ebay also:

http://www.ebay.co.uk/itm/BMW-E30-3-SER ... 1c2f29d1c5

Wouldn't be hard to copy the shape, but my bonnet is profiled and that would be a pig to profile it perfectly. Might as well just get it from BMW if it's £45!

[pac1982]

hate to sound like the sort of person who does a half arsed job but why bother getting all the old glue off if you gonna stick new foam on again?

surely the old glue wont cause a problem with the new foam sticking and once the new foam is in place no one will be any the wiser

[Cloggy Saint]

/\ That. I didn't bother removing the old glue residue and the new foam is still firmly stuck in place 3 years on.

[shedrool83]

Nice find.

also being sold by motormec by the looks of it, who sell all sorts of bmw parts and the nice floor mats

but saying that, for same price you just aswell buy genuine bmw, but might even be exact same part from same supply ? post pics when it arrives

Ben

a tech 1 1987 , as above if i go on that, it doesnt list any, but the 318is does but with a different part number to the 2 different ones on the cabby there, so its confusing

[BenHar]

up to and after 89

a tech 1 1987

It seems to me that you want the one that is "up to 89".

But if you put your VIN into the parts pages it should give you the exact part number.

Ben

[Kedge]

The 318iS one is covered in dimples whereas all the 6 cyl cars I've seen have smooth foam.

Just order the pre '89

[polsta]

will do, bit of confusion as to were 89+ different to both the early flat type and the is dimple type and id cabby was exact same as saloon

[BenHar]

put your VIN into the parts pages it should give you the exact part number.

Ben

[polsta]

£38 from bmw, ordered some today

wierdly, it would not come up for the saloon 325i, only cabbys

heres my old is, this wasnt the original foam

[age]

too lazy to read 2 pages about foam, but anyone take notice that the cut out for the throttle body isnt in either of the above pictures?
