Burning rubber smell

[BILT4ME]

I tracked my burnt rubber smell down.

The hood is a skin that is glued to the frame of the hood. The old black material used to glue the hood and frame together becomes brittle. As you drive down the road it vibrates chunks of that rubber adhesive off which then roll down the hood insulator and on the hot parts on the engine.

I replaced my hood insulator, upgraded to the Wit's End triple nozzle windshield washer ports and re-glued the hood to the frame with 3M marine adhesive.

Side note:
Man oh man! Let's take a second and talk about @NLXTACY triple washer nozzles! Holly S*+#, talk about project deluge good Lord it's amazing. Also Joey gave me the idea for the 3M marine sealer, as well as caution on using this product, it can make a huge mess if you get in a hurry. I was like..... What do I glue this back with, what's the Toyota part number..
.. I appreciate your solutions for problems I didn't know I had you're an invaluable resource and I appreciate the hell out of you!

The Solution:
*Caution* this is not a "how fast can you get it done process". Make sure you're using this product in the right temperature range as labeled, this is critical to a long lasting solution.

I broke off as much of the old black rubber goo as possible to prevent the burning smell going forward. used a plastic putty knife and plastic tools to gently work the old adhesive off the seams.

You'll see in the first photo I use a drop cloth to capture any loose chunks. I then switched to paper to prevent any goo from dripping on my engine when I'm reglooing.

I cut the tip of the 3M marine sealer at about a 45°. My first cut was about 3/16 of an opening and that seemed to work quite well for using the pressure of the caulk gun to force new goo into the seams.

Only reglue the previously glued areas.

Read the cleanup on the product you're using for me it was acetone, in a few areas I use my finger dipped in acetone to make a smooth edge forcing the glue into the seams.

Gently, very gently set the hood down don't close it. Resist the urge to mess with it for at least 24 hours.

A trip to the Rubicon, many highway miles and other off-road trips no burning smell.

When you close your hood it should make a thud not vibrate and sound hollow. While driving down the road if your hood skin is loose you'll actually see it vibrating in the wind and when you close your hood you'll see and hear it vibrate as well. This issue is common with our 80 series landcruisers and the symptoms are an indication your skin is loose, in need of some love.

3M automotive sealer also works but I went with the 3M marine grade once I looked at the temperature spread for the two different products.

Storage:
So, you finally found the right sealer it might not have been easy.... Now you have a quarter to 1/3 tube left do you really want to throw it away? Cork it, Wrap it into Ziploc bags, put in fridge for a rainy day.

Is that a factory 80 series hood insulator?

P/N?

Where did you obtain it? Local dealership or?

Why yes it is a factory insulator , I picked it up at my local dealer who is fair on parts. I do prefer Wits End for all the other goodies though.

Hood Insulator 53341-60100, shop around and/or talk to your dealer parts department, they have wiggle room.....
Don't forget to upgrade your nozzles and tubing while your in there. @NLXTACY has you covered. I am in the process of replacing all my hood rubber seals, cowl clean out, and replacing the plastic intake screens.

I’ll have to look at / under my hood liner - IIRC it was missing a buttonhead retainer when I bought it & I replaced it but I’ve ran the liner its’ whole life.

Strangely, it was (think it still is) - missing the headliner buttonhead clip right behind the sunroof & center of cab - how that was lost I’ll never guess.

But to the OP‘s point, I’ve never removed the hood liner so whatever crumbles, goes to the PS area - always noticed the smell on dry days at my old house as PS was closest to house front door / always walked in front of 80 after driving.

That was ~2000/01 & I’d just gotten it from the org owner in fatcat hills / California - some 110K on it & it was doing it then.
