Hi friends
my car is a 1991 w201 2.5 NA Diesel
recently i feel in the clutch pedal a metalic noise and also i can hear it ithink is coming from trasmision area (slave cylinder maybe) during pressing and depressing the clutch pedal
the noise is noticable when the car is hot and also get worse with driving alot
the clutch is working properly exept some noise in neutral
any ideas ?

PS: i dont have time currently thats why i still had my previous brake problem in my other topic

thanks alot my friends for your help
i learnt alot in this forum thank you

Likely throw out bearing if it is a rotational noise whenever the pedal is depressed. You will be pulling the clutch & replacing everything.

no its not a rotational noise
i think its from the slave cylinder because the noise is noticable just when moving the pedal

The throwout bearing is what allows the clutch shifting fork to move the assembly in and out without grinding everything to pieces. Metallic grinding or rattling noises when operating the clutch pedal usually start with inspection/replacement of the throwout bearing. It takes a beating over the life of the car and is a very common wear item.

Yep, it's throw out bearing. Slave cylinder failure would just keep the clutch from engaging at all.
