Clutch pedal adjustment gone wrong? Clutch issues.
 
I'll keep it short. I did the clutch pedal adjustment yesterday and ever since, I kept getting a clutch smell when I drive the car, no matter how I adjust it. It's back to stock height now, but now when I'm shifting under load I get a really weird feeling in it. I can feel some sort of feedback from the pedal to my foot that hasn't been there before. I want to say it's a throwout bearing, but I'm not experienced enough to know.

Anyone have any idea what could have gone wrong? It got so bad that when I started the car from a stop earlier, I heard some metal on metal rattling as I put the clutch in to get it in gear.

Thanks in advance.

Your clutch is not fully engaging because your master cylinder piston is not fully extended.

You lowered the pedal with the switch adjustment but did not adjust the clevis at the end of the master cylinder, or did not adjust it enough.

The bearing itself may be toast because you've been driving around with it under load.

Your clutch may also be toast because you've been slipping it.

First, adjust your clutch rod properly.

Then, if your clutch doesn't slip, you're lucky.

Also, if you still feel rumble/sound in your foot, your throwout bearing is toast and very close to seizing/fragging.

So you're saying..... There's a chance?

It depends on the source of the "funny feeling" in the pedal. If you feel any rumble at all, that's a bad sign.

Another thing to mention is that I didn't feel any slip in the clutch. I watched for that

But you said you kept getting a clutch smell. That's good that you didn't feel any slip but clutch smell is clutch slipping. Are you sure you didn't just smell grease and schmutz burning off of the exhaust pipe?

Well, we did change the transmission fluid and made a huge mess.... We got it on a lift and accidently had the black fiberglass under the hoist thing. So we just bent it out of the way and it got everywhere..... Could it be that?

I also just readjusted it go be "slightly under" the gas, so back to adjusted state. It feels much better and I get way less feedback from the pedal now. Although I still get a sort of "creaking" which I think is coming from the wheel well and not the transmission

That sounds much more reasonable. No worries. It will burn off.

Adjust it to be even with the brake pedal at the absolute lowest. Make sure the clutch switch is backed out as far as you can get it without unscrewing it.

Then adjust it to be level with or a little higher than the brake pedal by twisting only the master cyl rod. You can turn it to your heart's content without unhooking the clevis.

Tighten that down and then adjust the switch so it just comes into contact with the rubber bumper on the clutch pedal.

Done.

adjust the rod length and hand tighten the lock nut. turn on your car and put it into 1st/reverse and find the grab point of the clutch without adding gas (so you creep slightly). get the grab point to where you like it. tighten the lock nut. go for a test drive.

don't adjust the clutch pedal just based on height alone.

ryoma's right. I used to preach hard core about not adjusting to height. It's just that after having adjusted a dozen of these, I see a definite trend and have softened my position on the subject.

I want to thank you so much. It's good to go and it seems back to normal! Good catch with the fluids burning off the car! Thanks again.

Most welcome. Glad it's ok. Happy motoring!
