I have a 2013 RSpec 2.0t. I have to keep pumping my clutch. I have pulled air from the system 2 times. Gets worse the hotter it is. We ran a scope in the bell housing and there are no leaks and the clutch pedal no leaks. Not missing any fluid either. Once I bleed it it stays firm and then it slowly starts to sink as you drive. First time pumped it 5-6 times and did that 4 times. Second time pumped it 15 times and bled it 10. No change. Ideas?
