Title: Road noise - reduced using additional rubber seals
Post by: chris_i30gd on October 10, 2017, 21:37:08
I wanted to share my experience about buying and installing  extra rubbers for doors, bonnet etc
Something like that
http://www.youtube.com/watch?v=dp8pL-NiAw0 (http://www.youtube.com/watch?v=dp8pL-NiAw0)
but I have not bought a kit but individualy rubbers p type z type etc. I have links below in my second message.

After installing them I hear for sure  less road noise with a  cost of rubbers that was only 20 pounds. I have tested the car to roads that are harsh and the noise is
reduced significally and I can hear much better the music! Also doors closing noise is better( just need more pressure to close). I can add some photos about the changes I have made this week.


Regards!

Seems like a good idea for that cost! Thanks Chris. Did you buy from the guy that made the video. Do you have an ebay link?

Sounds like a good result (see what I did there :))

Shark racing have been offering something similar though a more complete door surround kit for several years that they say drops interior noise levels by 7 decibels  :link: WindKeeper Silicone Noise Suppression Molding Kit - Shark Racing (http://www.sharkracing.com/windkeeper-silicone-noise-suppression-molding-kit/)

Couldn't seem to find any cheap universal kits on Ebay. The one you linked to Craig only does doors apparently, not boot and bonnet. Says you have to take weather stripping off then reinstall. Is ours removeable?  :undecided:

I just had a look at my doors, the seals are removable - the top around the windows simply pushes into the bead lock though the lower section appears to have plastic push studs so I'm unsure of the attachment process, there are also the seals which attach to the car body side which is a push on seal all the way around so that might be the area they are saying to attach the new seal :undecided:

The bonnet of most modern cars should already have a rubber seal across the front lip, if not I don't see the bonnet as being an issue with wind noise really anyway as most noise seems to come through the doors.

The other issue with sealing the bonnet is engine heat wont be able to escape which will drastically increase under bonnet temperatures.

if you have a Clark Rubber store over your way :undecided: they also sell all the different types of seals so could possibly match up and make something similar.

Just checking the Shark Racing photos again and it attaches to the body side seals which are fully removable on mine, you would take them off - push on the new seals and then your original seal is supposed to push back on over the new seal in the original place.

Cheers for checking Craig. Wind noise is very low in the PD. Wonder if it reduces tyre noise at all?  :undecided:

I doubt it, most tyre noise seems to be related to lack of insulation in the wheel wells and the struts are also situated very close to the base of the windscreen which acts like an amphitheatre.

I have noticed improvement in tyre road noise after installing
z shape rubber in A pillar (in front doors). The noise and air while driving enters also from the opening of A pillar mostly
and with z shape rubber this opening is not open any more. Look at the video in my first message in 3:23 and this is the most important place to put rubber and reduce road noise.

I have used these rubbers:

I have used Big D Rubber in bonnet  and back boot outside of the black part of boot of i30 gd
P type rubbers in botτom of all doors and Z shape in pillars and in baψk top of boot

There is a road that I drive often and I couldn't hear at all  music and was so annoying. Was so harsh and so much road noise....
Now the  road noise is half  in my ears and I am so happy with the result. In 10 days I will put my winters tyres that are almost new
and I am sure the car will be also more quiet and for that reason.

I can see the benefit of the extra seals around the doors and hatch though as I previously mentioned there is a reason the bonnets are not sealed and that to allow heat to escape, over time I would expect the higher under bonnet temperatures to have some detrimental affect on electrical components plus it will definitely increase the intake temperatures.
Title: Re: Road noise - reduced using additional rubber seals
Post by: chris_i30gd on October 12, 2017, 20:56:01
I have that in mind and I will make changes in the bonnet rubbers  if necessary.  Thank you CraigB.

I haven't notice any change now, it's getting colder the weather and so in winter I will not have problem I think.
But I would like your opinion for the extra rubber in bonnet.... including maybe some links with details from net if possible :)

 I was wondering if there is any car model that  has extra rubbers in bonnets from factory. The air can enter in the bonnet even with he new rubbers while driving.
Previously in bonnet I found dust inside and small objects passing through and the air filter when I changed it a month ago has leaf from trees!.


Title: Re: Road noise - reduced using additional rubber seals
Post by: CraigB on October 12, 2017, 21:03:38
Dust will get in not matter what you do as most dust would come from underneath off the road surface and through the radiator, the seals also wont stop leaves entering the air box as they obviously enter from the air intake pipe.

Not much you can do about the leaves in the air box, as long as you periodically inspect and clean the box and filter it'll be fine :goodjob2:
Title: Re: Road noise - reduced using additional rubber seals

adding  extra rubber in bonnets :) I respect CraigB opinion so I would like
some extra info about that please.

I wouldn't be taking notice of what the seller is the video is advertising, the Chinese would sell you a new mother if they thought they could :lol:

Don't know of any links :undecided: I've never searched for information to explain what is simple physics really, heat rises and with the seals you've prevented it from escaping = higher under bonnet temperature.
Title: Re: Road noise - reduced using additional rubber seals

I think I will remove them
as I understand the issue and ur thought.
I also had the same thought.

Just wanted to read if possible some links about that.
I am some of a few persons in the world that I put these rubbers in bonnet so?

Yes I agree also. Just now the temp here is 6-20C but will get colder next month.


I will remove it  but I  liked it as when I washed the car, no water in engine bay

plus the engine bay stays cleaner generally!

Because my PD has 18" wheels with low profile tyres there is still more noise on some of our course bitumen than I would like.

Update: I tried our three auto accessory shops and none stocked the rubbers but they ended up referring me to rare spares who have a big range (probably 30 different profiles and sizes or more!) BUT they range from around $4 to over $10 per metre, so way dearer than on the net. I think I will go online and take Hati's advice.  :goodjob:

Edit: just ordered 8 metres of D, 3 of P and 4 of Z from premium Ebay services via China for $28 including postage.  :victory:

I have removed the extra rubbers from bonnet.

I am sure that also this extra rubber
help reduce harsh noise from road as it separates the bonnet from the
bottom part and reduces vibration that enter from bottom part of the car to the bonnet and internal of car so.

Anyway. It's better to have less heat in engine bay anyway :)

Great  to have them in forum.

By the way any experience of others and maybe the

best way and place to put extra rubbers is still open for discussion

to maximize the benefits.


By the way I mention again  that I am very very pleased with the oil and additive
that I added to my car a month ago. (Liqui moly 4600 oil and ceramic additive to  oil from the same company)
After 1000km the engine is working much smoother, with less diesel noise (almost no noise) and  seem to work better than using  the oil from  the dealer here!
I used it for the first time. I have also a citroen c3 diesel that is 9 months  car and euro 6 diesel in engine and is 2-3 time more noticeable the engine noise from inside and outside of car than i30's diesel 1.4

Extra info about the rubbers.

I have removed the rubbers from bonnet.

The road noise etc is almost the same  with or without.

I have noticed that the consuption when I was having the extra rubbers in bonnet was increased alot!
Maybe because the engine was more warm and hot than normal? I have removed teh rubbers in this place
and I have notice improvement in consuption. So by cooling the engine is working better and more efficient?

Hmm, I think this is definatly worth a try, low cost and potentially high rewards. Wind noise started to bug me more when I got the worst of the tyre noise out.

My Hankook ventus prime 2s make an awful noise now that they are worn to the markers. Just waiting for the forecast to go subzero before switching over to my studded tires. Next season I can buy some good summer tires!
Title: Re: Road noise - reduced using additional rubber seals
Post by: chris_i30gd on October 16, 2017, 21:08:44
One extra tip about this cheap way to reduce road noise and to be more successful.

Need to add some insulation (even some plastic sticker will do the job to cover any hole in place I show in image).
When someone open the front 2 doors, there is a black insullator  vertical shape like rubber to the back of the  doors.
(https://i.imgur.com/iAIrLhm.jpg)

Need to add there some more insulation even  a plastic sticker not to have this vertical insulation with empty space or moving :)

One final tip is to reduce tyre pressure a little bit. For example in my car normal min pressure  is 220psi according to the manual. and even 210 psi make the  car more quiet. I had my tyres 240psi in pressure and ride was more noisy.


Regards!

I had a short trip 250km in distance today and I can say I am very happy.
The car consuption is less than before and after my 4rth year service
and also with less road noise after installing rubbers.

In the trip I had an average consuption of 5.2lt /100km that is lower than previous trips and I was running quite fast  90-170 in high way etc. 
The trip had 200km of highway 10km in city and 40km of non high way  village road.

No reduction in noise recorded so far with  the additional rubber seals I bought.  :disapp:

Maybe it's because I'm a lazy sod and they are still on my printer in the office.  :crazy1:

Problem is I need to give the car a very good wash and dry before I do it and then watch the video to see what goes  where. Plus, I need  to do some before sound testing on a selected road with a suitable phone app.  :undecided:

Ok, so here's my feedback on the seals.

I added another ring of rubber seals around the rear hatch as shown on the how to video using D shaped rubbers. There is only currently the one seal on the rear hatch.

I tried to do the doors with P and Z rubbers, but they didn't really want to sit right due to various ridges on the door edges resulting from the way the doors were manufactured. After thoroughly inspecting the existing seals on the front and back doors of the PD and the wife's GD Tourer, I can't really see the need or benefit of a third seal. There is a seal on the door and a seal on the frame making an effective double seal and the way they are done the B pillar is sealed flush with rubber.

So at this stage I've aborted doing the doors. I still have the remaining rubber if I decided to have another try. They were pretty cheap so not going to stress.

For the record, I downloaded a sound meter app for my Android phone and tested the road noise on course bitumen near my friends house at 100 kph on a dry sunny day and it topped out at 81db (on smooth bitumen it was much less as wind and engine noise are very subdued at that speed in the PD SR)


Driving on the same course bitumen today, it sounded just as loud although I haven't tested it with the sound meter since adding an extra seal to the hatch.

Thanks for being the guinea pig Dazz. I noticed the double seal around the doors myself, didn't think we could do much better than that. The tail gate is too far for the front row to notice much difference, so I'll probably won't worry about that either.
Title: Re: Road noise - reduced using additional rubber seals
Post by: Dazzler on January 14, 2018, 19:25:18
I might still have another go at the doors at some stage as I would love to reduce the road noise a bit more. I don't think it's the car as much as the stuff they are using on some of our roads down here. Everyone is complaining no matter what they drive.

90% of the time it is fine, just the 10% of highway roads with the coarse finish.  :cool:
