    Blower Motor Gasket?

    I recently bought a replacement blower motor but it didn’t come with a gasket. An old LMC Truck video on YouTube shows an installation with a pre-cut gasket. From looking around at various vendors, it seems that most replacement motors don’t come with a gasket. Olde Carr Guy on YouTube used foam...

    I finally realized why I like working on my '81 C10 so much

    Yep--it's gorgeous. Well done. Question: Does your air cleaner use a THERMAC or is it electronic? I ask because I'm thinking of going back to my factory unit and I've been wondering what others are doing. Don't mean to hijack the thread--just had one quick question.

    Noise not likely blower motor/wheel—what else?

    Huh. Good to know!

    Noise not likely blower motor/wheel—what else?

    I stand corrected and, as always, so grateful for the members on this forum. I unplugged the wire and then the bad motor stopped. Looks like I’m in the market for a new motor. I like the way Rock Auto shows my options. Thanks again!

    Noise not likely blower motor/wheel—what else?

    Loud, awful noise under passenger dash, even when the heating/cooling/fan settings are off. What other moving parts are under there? My guess is there’s a vacuum connection that’s loose. Letting off the gas pedal sometimes quiets the noise. Grateful for any suggestions.

    Rust Under Molding/Trim--Magnets?

    I’m still considering doing the same. Part of my deliberation is whether to replace the molding with striping along the color changes. What did you do?

    How Best to Clear Fender and Cowl Drains?

    Many thanks. I’ve seen the windshield drains in photos but not yet on my truck. Will spend time on those—carefully.

    Highliner in a crew cab?

    Did you pull the trigger on a highliner? I have one that the PO installed. I'm looking to replace 4 speakers and stereo, and I'm wondering if additional components are really necessary for quality sound.

    Cowl Screen

    I just cleaned mine out today and wondered the same thing. Adding a screen is a good idea, but I'll have to think about how to make it look good. There isn't much room underneath for a clean install. Perhaps cutting holes for the clips would work, then trimming excess around the edge of the cowl...

    How Best to Clear Fender and Cowl Drains?

    Relatively clean, low-mileage, 1980 C10. After finding rust under the bedside molding stickers likely due to poor paint prep (see my previous posts), I am now in full rust-prevention mode. Today I got under the fenders to clear out the fender and cowl drains with an air hose. The problem is that...

    Thanks for the suggestion. Also, nice lookin' truck!

    Rust Under Molding/Trim--Magnets?

    That makes sense. The PO repainted the bedsides and my detailer opened my eyes to just how lousy the paint job was. So I wouldn't be surprised if the stickers lifted the paint. Though I only posted one pic, the damage is under nearly every sticker on that bedside molding. Many thanks for the...

    Rust Under Molding/Trim--Magnets?

    Yep--my 1980 has the same two tone trim and it all looks to be attached with the factory trim clips and adhesive. I'm leaning towards replacing with magnets or real pinstripes. Here's Part 2 of Dirty Dan's pinstripe masterpiece...https://www.youtube.com/watch?v=FofSG7Q0zJM

    Rust Under Molding/Trim--Magnets?

    1980 Fleetside Silverado is rusting under the bedside molding/trim where the stickers attached to the truck. See attached pic. I love the look but I hate the idea of re-attaching the molding/trim in the same way after repairing the damage. I vaguely recall someone on here mentioning he uses...

    Gasoline in vapor canister

    Thanks for the reply. My mechanic wants to replace my 3-port with a 6-port but isn’t certain it will solve the problem. Your post suggests the problem is likely elsewhere. Can you give me more details about replacing the selector valve? Sent from my iPhone using Tapatalk

    Gasoline in vapor canister

    I’ve heard a lot about tank switch failures and people going to one tank. Seems like we could get this right by now. Yes, I have two canisters—one for each tank I think. Sent from my iPhone using Tapatalk

    Gasoline in vapor canister

    Thanks for the reply. I do have dual tanks and I’ve been wrestling with problems from the start of this project. I have a 3-port valve and my mechanic is wondering whether that’s the problem and whether to replace with 6-port. If you had problems with 6-port then I might have other problems too...

    Gasoline in vapor canister

    1980 Big 10 running great but smelling gas in the cab. Lifted the hood to find gasoline dripping out of the driver side vapor canister. I assume that means that pressure is pulling gas from the tank to the canister. Any obvious causes or things to check first? Here is the pic of the schematic...

    Rough Idle / lower RPM

    Just had a 403 Olds rebuilt and the builder said to only use Wix filters from now on. Thought you might want to know that you made a solid choice. Sent from my iPad using Tapatalk

    Full Tank, No Gas

    Thank you, Bruce. The manual says that the passenger side tank is the main tank. Interestingly, it doesn’t talk at all about the optional driver’s side tank, nor does it give recommendations on how to drive with them. Now that I know, I’ll plan to drive on the main tank and only switch to the...

    Full Tank, No Gas

    It’s “run out of gas” on me three times now. The first time, I got about 10 miles down the road. The second time, 3 miles. The third time, 2 miles. After the second and third times, I opened both gas caps to even the air pressure, switched to the right tank, and fired it right up. When it...
