My engine pad is missing - worth replacing?

[KNS]

I replaced mine on my 1980 911SC - all I did was drop the engine about five or six inches and throw a blanket over it, didn't remove any engine pieces. It wasn't too difficult.

I just bought a '86 Carrera Cabriolet with the pad partially missing. I installed the new pad in about three hours. I removed the air filter box and the cruise control actuator. It was tough to get the new pad in place with the glue and I had glue all over my hands. IMO I don't think the noise level is much less, but I think it sounds better now. It definatelly looks much better.

Wow - the pads are thicker than I would have expected.

I bought the heavier weight sound mat here from the Pelican site.

I would love to quieten the engine noise in my cab which also has no pad. Is a new pad the best way or is some kind of pad under the rear seats etc a better idea?

I also have an M&K so not sure if a new pad will also quieten the interior noise at all.

new pad on the engine side of the firewall - if that is not enuff, then add a layer of foam with thick vinyl (heavy) floating on top of it to the interior side

I just removed mine from my '87. Don't hear the engine any louder than before from what I can tell.

My biggest regret; not ripping it out sooner!!!!

Buy a sound pad from our host, glue 20-25 small round magnets to the back of the pad. Remove all of the old pad that you can. Remove the air filter box and install the pad. It will look like a factory install and you do not have to remove or lower your engine. The install will take 30 minutes

That is b/c is was already old & not stopping any noise.

The magnets are a great idea as far as ease of installation. Do you think it will stop the noise as effectively as gluing it on? Comments on that?

Great post! I just drove our '85 from southern New Mexico to Prescott, AZ, about 600 miles. 80 mph on I-10 thru the desert, was 'cool' at first, but, the noise eventually was unbearable. Will add this to the project list!

IFSJA and now here? Unusual that we both have FSJ's, YJ's, 911's, and ties to southern NM!!

Particularly in the back seat, I'd think. My 7-year-old mentioned that it was warm back there the other day. And that's with a pad.

I can not tell any difference in sound between my magnet sound pad and others. I have had it installed for 6 months and it looks great. It is a simple solution that takes 30 minutes

Tell us about the magnetic sound pad you have Buckeye. My '80 911SC doesn't have a sound pad and my little girl gets hot in the back. I'd love to install one but would rather not drop the engine to do it.

You don't need to drop the engine to do the installation. Remove the air filter and the MAF sensor.

Bend back the retaining tabs and dry fit the pad. The center and passenger side are easy. It's a little more tricky on the driver's side trying to maneuver it into position around the cruise servo and deck lid hinge.

With the pad dry fit in place, work from one side to the other peeling down 8-12" sections at a time and applying the adhesive to that section. Press it into place, wait a few minutes for the adhesive to set up and move on to the next section. You probably won't be able to get complete coverage with the adhesive to the lowest portion of the pad, but the shape of the thing holds that in place.

Obviously easier to do it with the engine out, but it's an hour job to do it with the engine in place.

The magnets sound like an interesting idea, but as they lose their magnetism, you might get some annoying rattles. Be a good PO and leave a message in the glove box for the next owner.

I bought a pad from our host and bought 25 magnets from Lowes and glued them on the side of the pad that touches the metal. I allowed the glue to dry overnight. The next day I removed the air filter cover. I worked the pad into place, it will fit. I agree with an earlier post the magnets may lose their attraction. If they do I will do it again. The pad is only $70. It looks great, was easy to do and you do NOT have to remove the old glue

[Johnboy911]

I just installed a new heat pad and the engine was still in place. I had to remove the air box cover and the and the (air intake cover?). I also removed the rear trunk lid cylinder. It took me about 1 hour to complete the installation.

Cheers,

I just changed mine while the engine was out. Powerwashed a lot of grime and old glue residue off, then used some 3M spray adhesive to install the new one.
Looks much better, and very easy to do. The car doesn't sound quite as raspy as it did, perhaps, but it is still loud. The original carpet with it's lack of any further layer of dampening is probably more to blame at this point. With my RL8 headers and exhaust, a stereo upgrade wouldn't make sense before some dynamat (everywhere).

As an alternative to OEM or aftermarket fitted sound mat has anyone tried the Hushmat product. It's suitable for engine compartments and is a sound and heat barrier. It's fairly exlensive but may work better than the usual options.
