At the base of my C pillar, there is a blue spray foam insulation in the void spaces of the body. It’s a flexible foam and I’d like to obtain more of it. Does anyone know what product it is or what product GM recommends as a replacement? Thanks for any help.

It should be found by 3m it has a very special 2 part application gun. Only think I don't know is the exact product as there are a few to pick. NVH foam

That’s a huge help! Thank you. Nothing like rigging up some lighting to keep working after dark.

Are you spray foaming the floor of your truck? For what reason? They are the quietest trucks I have ever ridden in and hold cabin temp quite well in -40c Canadian temps with no winter front. Putting some big subwoofers in?

What are you doing inside your truck?

I’m sound deadening it.

I’m putting down butyl rubber then neoprene on top. Then, I’d like to fill in some of the void spaces with foam. When I got my first Sierra back in late 2013c I agree, it was one of the quietest vehicle I had ever owned.

 

Fast forward to this truck + long tube headers dumped before the rear wheel and well, 95 decibels cruising on the highway at 70mph just isn’t fun. Also, after 5 years of use, every creak and squeak that the plastic parts can make, well they’re making them. 

 

The disassembly was way easier than I thought it would be. I learned a lot. I also found a ground that was corroded so I cleaned all of them, put some dielectric grease and re-tightened. Fun project but time consuming.

Because it doesn’t expand. Also, not sure how well it cures in an enclosed space.

It will cure fine if it has the appropriate time. I wouldn't want to put anything that expands in, just going to make reassembly harder. Also I'd want something that wouldn't trap moisture between the floor panel and whatever you put on top.

Thank you. The 3M 8463 is what I found that the body shops use to replace the OEM flexible foam after a collision repair. Unfortunately it’s about $45 for 200ml. But that’s probably the route I’m going to go. The main area I’m gonna use foam is just under the rear window and the B & C pillars.

All of the exposed areas of the floor have already been insulated with butyl rubber and neoprene, using silicone as the adhesive. The reason for a liquid expanding foam product is only to reach some of the enclosed void space, like inside the pillars. An expanding foam product would be idea for that purpose. I read a lot about Lizard Skin. Seems like a really good product, but not ideal for this purpose.

I used lizard skin both the sound deadening and ceramic for heat and this stuff is great.  I'm redoing an 85 iroc now and I will use this again on this car.

      Oil Consumption

      By KARNUT · Posted

      No I didn’t watch a video of a person who analyzes oil for a living explain general oil usage. For clarity I did ask my brothers one who runs our equipment business. The other who runs our old ROW business about oil usage. Nothing has changed since I retired. Their personal vehicles or work vehicles use no oil. Not enough to see on the oil checking device. Then I pondered. I like to ponder. In this extended oil changing world with oil change countdowns or lights. If engines used say a qt every 2500 miles or up to even 4000 miles. With oil changes reaching as high as 15000 miles. Normal for most people is eight to ten. Vehicles should potentially be seizing up all over the place. Especially in hilly terrain. Just how many people actually check their oil? Maybe 10 percent. Those are the people that probably change their oil early. I like to research used car listings. I have five favorite dealers I check. They all list carfax with their listing. It’s rare to see vehicles with anything but extended oil changes. Transmission service, forget about it. I’ve seen Honda and Toyota certified vehicles up to 100K miles and ten years old. With nothing but normal maintenance. Isn’t nice we all have different experiences and believe our way is the best. You certainly get backup for whatever you believe. Life would be boring otherwise.

      RUMOR / INSIDER: 2027 Silverado Dealer Reveal NEXT WEEK

      By RobbertClaus · Posted

      Interesting rumor. Dealers near me have been tight-lipped so far, but if this reveal actually happens next week, I'm really hoping they finally give the HD a proper interior overhaul. The competition has been eating their lunch in the cabin department for a while now.

      Oil Consumption

      By Chuck FB · Posted

      There are a few good takeaways in that video that pertain to this thread, certainly the possibility of the oil control rings having buildup, the fuel injectors and how clean or not that they are ending up affecting the pistons rings carbon buildup, and the fact that its normal up to a point for a given engine to use some oil, and that the oil quality that is being utilized is part of that ring clogging up issue as well.   I was talking with a neighbor yesterday who has a baby LZ0 duramax and he had bought it slightly used but it does consume some oil and he has switched over to 5W-30 Euro spec oil and in this case that never made a difference in consumption over the factory 0W-20 recommendation. He finds it uses a quart in about 3500 miles and as he goes a ways over that distance he adds oil to full and goes another 1000 miles or so and then changes oil and is typically at 40% or so left on the oil monitor at that point with his use case of quite a lot of highway miles and more limited in short run use. I don't know what other LZ0 engines are doing for oil consumption but that is what his is doing.

      Ok well I guess Lake disagrees with me on a few points. I call oil consumption pretty basic. Rudimentary. He calls it "really complicated." I think 1qt consumed in 3k miles is a lot. He says that's normal. In 22 minutes, he'll use his natural talent to explain oil consumption to anyone watching this video. He covers everything from obvious engine damage to how normally functioning healthy engines consume oil by design. Lake explicitly states how you drive will impact oil consumption.   Shut up and watch:
