New engine in, clutch problems

[lowydin]

So i had to get a new engine put in my car (95 TSI AWD) at about 105,000 miles back in late march. So i took it to the shop they put it in with out any problems im assuming. But before all of that i put in a new clutch (act 2600), new master cylinder, Mits T/O bearing, and the lightned flywheel back in early novemeber. Had no problems with the clutch ever. Now heres the problem, When the car is on the lift, the clutch has pressure works normal. But when the car is on the ground like its suppose to be, the clutch has no pressure and falls to the floor. The most annoying part about this is that there basically blaming me for this and saying i mad modifications to my STOCK pedal assembly. But i had no problems driving the car before i had problems with my car and in fact had no problems with the clutch while i did have problems. So you guys have any ideas has what could have happened?

Thanks matt

they probably moved a wire or cable to install the engine, and when the car is dropped, the weight of it is pinching the line and causing it to malfunction, only thing I can think of
