Popping sound after i release the clutch?

it sounds like the u joint or the throw out bearing

if the clutch does not feel right or feel a vibration or wable one or more of the spings in the clutch might be broken,release bearing mingt be seising up,could be as simple a u joint.give the drive train a good look.

i have run into that problem.are you having a hard time getting the car to start? i let it go and it was a bad idea. look at your firewall where the clutch master cylinder is. there is a plate that is like wielded on. have someone sit in the car and push up and down on the pedal while you look at it from the outside. if you see the whole clutch master cylinder move when they push on the pedal what most likely happened is that that plate is separating from the firewall. i had to get a plate of steel made and up it on the inside of the car to pull the master cylinder back in to where its supposed to be.
