I got in my car for the first time in a about 12 days and before I even turned it on, I pushed the clutch in. It made a "rusty, old spring noise" (if that makes any sense). I started the car and it still made the noise everytime i pushed the clutch pedal in and released it. I did some stop and go driving before I got to the highway and it kept making the noise. Then I drove for about 20miles on the highway and pulled over to listen for the noise again because I couldn't hear it at highway speeds. It had disappeared! I checked the clutch fluid level and it was full, like always. Any ideas what this is? I don't even know if the clutch pedal has a spring, but I just assume it does.
Thanks.

Mine is doing the same thing as we speak. I was told to lube it up with vaseline or something like that, but I haven't had any time. But yes, on your clutch pedal assembly, there is a large spring on it.

Is the spring on the cabin side or engine side of the firewall? I'll give that a shot right now.

it should be on the cabin side just get some grease on it, mine does the same, no biggie

Would vasoline be ok to use like suggested or should I use something else on the spring?

i'd say use something else but vasoline should work

what type of grease would be best for the spring?

hmm not sure :

anyone have an idea of what type of grease/lube to use on the clutch pedal spring?

You could use wheel bearing grease if you have any laying around
