Ok heres the problem. My clutch gets hard to push in when the engine and transmission warms up, also there is a popping sound. For the love of God someone plz help me figure this out so i can fix it. I recently replaced the cable (yes its routed correctly) and put a firewall adjust on it. The previous owner had already installed an aluminum quadrant. Now I had someone push the clutch in after i got the car nice and hot and the popping is definately internal. It is not the cable/or the firewall/or the quadrant. So my pea brain thinking is the clutch itself or the flywheel or throwout bearing or the clutch fork. I would like to pinpoint the problem b4 i get into all the removing of the driveshaft, tranny, exhaust not nessesarily in that order. Could my flywheel be warped? Can a clutch fork go bad? Oh yeah and b4 yall ask yes it did this b4 the new cable and firewall adjuster. Plz Help Me. I beg of you. On my hands and knees.
