24v hood sound insulator

[man of kent]

Looking for a very good non sagging and sound hood insulator for the 24v. Vauxhall dealer tells me the insulators are different for each engine ??

Trouble is I'm in Kent so might be difficult to get it to me.

Not so... I'll be travelling the length of the country over the next week - Kent to Loch Ness!

[man of kent]

Anyone got one pdq for Murph to pick up?

Dont forget I'm still looking for a good 24v hood sound insulator if anybody has a hood hanging around from a breaker. Apparently the edges do sag as the material is different to the 2.0L

ABS tell me the 2.0L insulator is much better quality. I think GM paid a lot for the 2.0L tooling mould as it was a much bigger production run, but as the 24v was lower production probably didn't want to go for a deeply moulded tool that was expensive or a higher quality material.

Anybody know if you can put a deep depression in a 2.0L insulator so it misses the engine. Was thinking that locally steaming the insulator and then applying a weight until dry. You can steam bend wood, so can you the insulator?.

The edges of mine on the Diplomat were perfectly OK until it spent the night facing into a howling gale and driving rain which permanently softened the edges and they sagged.

I eventually glued the edges to the bonnet with Evostick contact adhesive a couple of years ago and it hasn't irritated me since

Mine is glued up as well but the edges are damaged badly as its been hanging down for a long time & the stuffing has gone.

Here are 2 photos illustrating the 24v and 2.0L hood sound insulators. You can see the deep form in the 2.0L insulator that is made out of some form of hard board and is almost self supporting.

The second pic is my 24v insulator which as you can see (poor pic) is fairly flat and unformed and made out of a softish material with what looks like fluffy filler behind. Thus it tends to sag and get damaged.

The different method of manufacturing is because the 2.0L sold in much bigger numbers, vauxhall could spend more money on materials and forming tools. The 24v insulator is classic low production material.

On another forum somebody suggested they were a straight swap with the same fixings. You can see here the fixings are in different positions.

I want a good 24v one with the form as shown in the second pic. Is the 2.6 and 3.0 12v the same as the 24v?

[Land-Barge]

Fixings look to be in a similar place to me   Cant comment on wether a 12v is the same because the insulation from mine has been missing for years

i will look at the one i have and get back to you as far as i can remember its pretty flat in comparison to your 2.0 one!!

Definitely flater. The material edging has gone on my 24v so re stuffing and stiffening isn't an option really. If a 2.0L one is available, I can take mine off and see if I can do anything with the original. Might fall to bits around the edges if I do. I think mice have been at it.
I've the club 2.0L car but dont want to take that off as its for sale and thats cheating.

There might be a 24v one available but its in Penzance! Guy hasn't decided whether to break or not.

This is a very interesting post as I have been perplexed by my Hood insulator.

Without trying to hijack this thread, I have replaced the original insulator from my '89 Gsi 3000 (12 valve) which was indeed the old saggy fluffy one with hardly any definition of shape in it whatsoever....

I found a virtually new one fitted to a Carlton I found in my local breakers yard about 6 years ago, If I remember rightly it was something like a 2.0 CD spec. (possibly on a 'J' or 'K' plate, so one of the last Carltons made).

It is identical to the one in the 1st photo (a good sturdy card-like feel to it). The reason I have been puzzled by the difference is that I have been examining the pattern of the insulator and I've noticed that it doesn't seem to mirror the form of the components under the hood, raised things like where the cam cover sits, inlet manifold (plenum) Throttle body etc... Obviously other parts are fine, expansion tank, brake fluid res., battery, screen wash bottle etc... as these are pretty much common over all models/years.

I'm assuming that the later insulator I have fitted to my older engine bay will be okay and not foul the top of the engine, it seems to be okay when I close the bonnet, just hoping it won't touch certain parts that get hot (although I know it will be fire/heat resistant (?))

That said, if the old one which probably sagged down into the bay didn't cause any problems, then this one should be fine.

Again, sorry to hijack the post, just thought I'd share my experiences on this topic.

P.s: The fixings are in the same place as the bonnet is the same for all Carltons and the holes are common across the board.

What year are the bonnets in the photo.

You may find Preface/facelift are different.

I would not expect there to be a difference, but if there is, it would be engine size not model.

Both 1993.

why not just glue on a acoustic carpet

why not just glue on a acoustic carpet

Thats not very original! I'm a great believer as a classic car lover in keeping the cars original, within reason. I'm old enough to remember the classics on the road as everyday cars. Dont think they used acoustic carpet on the hood!

Before I upset anybody, nothing against anybody else doing what they want with their car. Its their car.

[kevinfourlegs]

You share the same sentiments as me with regards to keeping classics period.
