Bonnet liner replacement - pics and a few tips

[poolnoodle]

G'day Guys,
Just a few photos of my engine detailing progress.
Before:



Removing the glue holding the old deadener is a rotten job, I found the best way to do this was to douse the area liberally with turps, leave it to soak for 15 minutes or so then attack it with a plastic plasterers broad knife

Gave the whole thing a good hose down

Fixed the new deadener - this pre cut item (well, three items) came from Pelican Parts in the US. The genuine item was 3 times as much here and I like the cellular look of this. Also gave the bonnet underside a good cut and wax.
Stoked with the results. Will undertake further engione bay tidy up with the bonnet off and post results when done.

nice...does make a lot of difference and usually one of the things you see when you open the bonnet, think i might do that as well, depends on how bad mine looks tho...

[The_Diddler]

Its one of those jobs that really makes a difference, looks like new again

[jaymos]

i was gonna start a thread on this, mines virtually non existant, does anyone know the best place to get them over here?

[Topblag]

Stealers - about £25 IIRC.

The dimples deflect air around the engine to help cool the M42

Isn't this the standard M42 bonnet lining?

[ChemicalAl]

Was thinking about doing this, and now that I need to buy a new bonnet, i'll defo be spending a wee bit extra at the stealers to get this completed.
Looks great, however I think the cutting and waxing may have gone too far OP!

[Gert_8]

so, come on then, Poolnoodle, where did you buy it from and how much, mate?!

[Bump]

[ross_jsy]

whats the point of the lining?

is it just a sound proofing thing or does it limit heats effect on the engine?

[Gert_8]

Sound proofing, I'd say.

[ross_jsy]

sweet, that can come off then!

[Gert_8]

Usually find it on Diesels. Surprised to see it here, really. I can't remember, so I'll have a look over the weekend, but I don't think my Cabbi is lined..

Special pink galvanised finish, no?

I saw someone on a resto thread complaining that the paint on their bonnet was cracked by heat from the engine when someone ran it without one of these. I've damaged mine leaving a charger in there and you can see where it clears condensation on that patch really quick when you fire it up. Might be heat & sound insulation...

get a decent liner instead of the spongy crap, these help reduce tappet noise on M40's !

What t this off and where do i get one?
That looks great.

[hennabm]

These were fitted to M3 or 324d.

Both parts AFAIK are NLA. They sometimes come up on ebay.

[Kedge]

Also fitted to the 325e as well. I think they may also be different depending on which model they came from.

[dirtee-herbert]

I think I am going to try and get my hands on one of them. I think they look far better than the foam. And I need to do my new bonnet after it gets re-sprayed. May aswell do everything at once.
