Default Clutch pedal won't return to position - cable not broken.

On my 3rd drive ever of my 911, I ran into a new problem: The clutch pedal broke.

...or so I thought. We checked the helper spring and and cable underneath the car, and both seem to be okay. When you move the pedal, the cable moves just like it should when at the transmission. The helper spring isn't broken, either.

This problem didn't happen over time, it was all at once. I went to shift from 2nd to 3rd, but the car would go into 3rd. I thought, "what the heck?" so I put it in neutral and took my foot off the clutch... and the pedal didn't come back!

Anyone have any ideas what the problem could be?

I think it would go into 3rd because the clutch was not actuating with the pedal... But I don't know. The spring at the floorboards seems to be intact. Would that help pull the pedal down and not up?

Sounds like a broken Throwout fork. Not unheard of. Assuming the Omega spring and the return spring on the trans are intact.

What's the skinny on the throwout fork? It sounds painful and expensive to replace...

They can weaken, and bend. You'll have to drop the motor-I don't think it is crazy expensive...but, while you're in there....

Uh oh, it's one of those "but while your in there" kind of things...


While your in there, replace the 915 with a G50?

No need for that, but a clutch perhaps, and whatever sealing that may need to be done. Sound pad, general cleanup, etc. I'd look at it as a $2k project, maybe less.

Oh! Well then. That's unexpected. Is there any way to know that's the for-sure problem before I go through the trouble of dropping the engine?

I think you need to double-check everything first. You can undo the clutch linkage at the trans and see what may be binding through the assembly. If you have access to a boroscope, they are cheap at HF, you can look down the inspection window in the trans bell housing. The forks are known to bend, however.

I'd think that would go straight to the floor when pressed, but return via the springs.

No, you have it correct, I would think.
