I took my seat out again and peeked through the slit in the carpet and found some white chunks. They almost look like the solid chlorine pieces for the pool. what is it? i have a picture if needed.

please post a pic of it. t top car?

no, hardtop. it's more than just a little too. i can feel it packed in up near the front of the seat.

hows the floorboard? does it feel soft? my first 2 guesses would be corrosion or mold. since theres alot of it, i would maybe pull the carpet up

no it's not soft. they are hard pieces.

do you kow if it goes the whole floor? kinda looks like plaster for sheet rock. can only assume so much with 1 pic and little history of the car

I'd pull the drivers side kick panel and door sill so you can lift the carpet and get a better look. There shouldn't be anything under the carpet except some jute padding, and maybe some tar paper sound deadener. I've had the carpet out of at least 15 thirdgens over the years and I've never seen anything that looked like that. It could be a build sheet, or assembly line garbage, or a shipment of narcotics from Columbia, you won't know until you look.

I can't tell other then in the area in the picture and that other area near the front.
drew, did any of yours have a slit in the carpet where I showed?

i agree with drew. maybe someone did a sketchy repair to the floorborads or it can be something else.

They've all got the slit for the seat wiring to pass through.

including the ones without power seats?

Yep. I've never owned a thirdgen with the power drivers seat, but they've all got the cut out.

oh well this is the passenger side.

that spot could be for the seat belt harness. right drew?

The wiring to the seat belt goes to the drivers side seat belt retractor... The cut in the passengers side is probably there for the cars with power lumbar. Either way, all that should be under the carpet is fluffy gray jute padding, and steel painted body color. I wouldn't be the least bit surprised if it were a petrified paper cup, or other garbage from the assembly line.

it's stiff and not soft at all, but it is a little brittle.

The suspense is killing me... Have you pulled up that side of the carpet to see what it is yet? I gots to know!

i vote for spackle rust repair!

i also belive its rust related

well it can't be rust repair. it wasn't repaired until i got under there.
I haven't gotten it up yet. that might be the side that has a screw I can't get out because it's rounded. it was too cold to work on it today.

... think you just found the PO's crack stash >.>

Something tells me, we'll never know.

there is a rounded screw on that sill board so i can't get to under the rug.

Florida car ? My vote is from beach sand/salt and wet feet !

Put just a little toothpaste on the tip of your screwdriver and turn slowly... You might also try using the next size larger screwdriver. A drill driver can work sometimes too. Beyond that, drill in the center with a 1/8" drill, then when the panel is out grab the shank with a vice grip and turn it out.

it's not sand as it didn't fall apart in my hand when i rubbed it. i actually should have a piece in my vacuum.
drew, I should try that soon. I am working on a header gasket currently.

tried drilling and got nowhere.

What's the possibility that it's seam sealer??

pretty odd seam sealer not in a seam

the suspense is killing me, i need to know what the hell that is

really? I gave it a shot at least. 1 drill bit twisted in half, and the other must be dull although it doesn't look like it because i am getting nowhere with it.

Damn, I read all 31 posts and I still didn't find out what it was!

Get a couple titanium drill bits and give it hell... One screw can't keep you out.

what is it?!?!?!? lol

My guess is it is the white paint from the factory mixed with a bit of corrosion under it making it start to peel/flake off.

news?

yea I just got a couple new bits so I can try drilling soon.
I had pieces of the white stuff in my vacuum, but I vacuumed right over it so they weren't clean to show you. I did noticed it looked like they had little pores in it...little circles.

I've got another problem.
I drilled out the screw so now it separates. But, the screw that holds the sil place and kick panel together just turns. It came up some from the start, but won't come out anymore and it's starting to get rounded. this is weird

see if you can gently pry up on it a little and turn it at the same time sometimes that helps

i did that and it didn't seem to do anything.

Just pull the kick panel up... That screw is a bit of a pain to get back in the hole, so usually it's just threaded into the carpet, or has the jute padding wrapped around it.

i forced it up real hard, but i'll try getting it out in the next few days.

your killn me smalls

i just read this whole thread and the suspense is killing me. AHHH! lol

AHHHH SAME!

When he finally finds the problem he should private message every1 who viewed so we can find out!

Haha. Well posting it here will suffice I think. I'm really interested to see what that is. It's probably coke or something from the last mafia that owned it.

This thread has turned from finding out what the mystery substance is into a never-ending quest for sill plate removal. We might never know what it is!

I think we're hung up on kick panel removal, actually... So perhaps the easiest part to remove is keeping countless millions in suspense. LOL

ok then tell me how to remove it now that I've removed all the screws.
if all that's left is the seatbelt holder, the torx bolt won't budge for ****. ill try breaking it free again if that's it.

your whole floor is covered in pure, uncut cocaine...
