Any preferences on the type of hood insulation pads to buy. I have seen the OEM(looks like black foam) and and the aftermarket(which have silver foil look to them). Also any tips on removal of the old, crumbling insulation?

Thanks

The factory eventually went to no hood insulation starting in '89 I believe.

Have fun with the removal. I've done it to my early car (sold) and now my turbo. With the early car, I put a sheet over the engine compartment and scraped it off with a Bondo scoop. Then used 3M Adhesive remover to get the glue off. Pain in the ***.

For the turbo, I put tape next to the hood hinges so I could line them up, and took the hood off the car. Put it upside down on a paded box, and had it done in 1/2 the time--with less cussing. Then flipped the hood back over, and bolted it back on. Have at least 2 friends with you to remove install the hood. Pay them with a beer. I've read a lot of posts with people breaking the windshield by not holding the hood well enough. Even with removing the hood, it was quicker and easier-I used the same process by the way.

The early car was perfect, so it got original hood pads from Performance Products, and they looked great. I haven't decided what to do with the turbo. The 89-91 cars did not have anything but a pad above the distributor-maybe I'll do that-

yes,
plastic scraper ( i used the wife's pampered chef pot scraper)
3M adhesive remover to soak the area prior to scraping.

My advice is because of the high PITA factor, do it over a few weekends - 1/4 of the area at a time.
suck off the old insulation with a shop vac or at the car wash.
i didn't remove the hood and had no problem removing the adhesive, let the solvent soften the stuff abd it should scrape easily.
I purchased OEM pads, but after i removed all the old adhesive i decided not to re-install the pads

I have an 88 non-S Turbo that has no pads and doesn't appear to have ever had one...

My 89 S2 has nothing but shiney original paint there. The factory deemed the insulation uneccessary and that's good enough for me.

Just another tip: Cover the engine bay with something (garbage bags? Rubber floor mats, etc) so that you don't get any of that stuff in your engine bay as it's a PITA to clean up.

I got the OEM pads from some dude on Ebay. Something like $90 for both.

I put a plastic drop cloth over the engine compartment and got an old plastic spatula and scraped away. You don't have to get it clean as a whistle, but get it pretty cleaned up.

When you put the new ones on, line it up carefully and start peeling the backing off i little bit at a time. You only get one shot at it.

Turned out great! Keeps the paint from exteme heat.

If you can afford to take the car off the road for a day or two, take the hood off the car (you will need help from atleast one friend, two makes it easier). Lay the hood down on a surface that wont damage it (obviously not the asphault). Soak a few rags in the 3M adhesive remover and lay them ontop of the residue you want to get off the hood for a few minutes. Remove the rags then scrape away with a plastic bondo scraper. Its a good idea to wax the underside of the hood if you plan on leaving it bare, otherwise just reapply the insulation. I strongly recommend against going with the OEM stuff, id go with the aftermarket reflective backing type stuff.

plastic scrapper?? oops.. so thats what happened. Anyone else use a metal scrapper? Please tell me im not the only one...

Place a sheet over the engine.

Peel off excess insulation.

I put 3M adhesive remover in a plastic spray bottle. Spray, in a well ventilated area, scrape with a PLASTIC scraper. Clean up with a rag soaked with paint thinner, in a well ventilated area.

1 1/2 hours (tops) for me to do.

Wash and wax.

Probably lost a few brains cells. The ones I lost weren't being used anyway.

When they got rid of the hood insulation on the later cars, did they put any type of heatshield over the exhaust manifold? I've got a fiberglass hood, and have been concerned about the heat, I've ran the car a few times, and it gets pretty warm on top of the hood.
