Okay first of all, I have search many different forums and have not been able to fix this issue.

Basically I have replaced my whole clutch system. Wilwood Master cylinder setup for Zspeed, steel braided lines, upgraded pivot ball, brand new CSC, new clutch and flywheel.

Everything is installed correctly, no air in the line when bleeding and the clutch pedal seems to be working perfectly until I turn the car on. The second I turn the car on, the clutch pedal gets squishy and sticky. It doesnt release properly and I cannot shift into gears after about 10 seconds from having the car on. It seems like it is losing pressure in the system somehow. When I shut the car off, the clutch is fine and I tried bleeding it, no air in the line again.

Anyone have any theories on this? I am at a stump since I have replaced EVERYTHING. Also note that I removed the clutch orifice(or clutch restriction as some call it) that was under the driver side fender cover. I bench bled the master cylinder before i installed it and it seemed to pressurize fine, so i doubt the master cylinder was defective. Prior to installing the new master cylinder, everything seemed to work okay and that setup was the new clutch/flywheel, new CSC and the small steel braided clutch line that connects to the slave. I did notice that the clutch pedal felt a bit spongy which is why i decided to go with the heavy duty master just in case it fails again.

Any suggestions?

With your car off and sitting at rest snap a pic of the clutch fork position and post it up.

Doesnt make much sense what you are saying, It shouldn't change by starting the car. What clutch and flywheel are installed in the car?

It looks like the clutch is not set up correctly, The fork position should not be that far forward into the slave with a new clutch, Should be about middle way in the opening.

With it at rest can you push the fork backwards away from the slave? The release bearing should stay in contact with the pressure plate at all times, even at rest, If it can be pushed more towards the clutch after it has sat at rest the spring that holds the bearing to the clutch fork may be installed backwards causing it to push in on the slave as it sits.

And you boot is on backwards, big part goes into the trans.

No I am not able to push the fork away from the slave. So since the fork isn't sitting correctly, that would be fixed by adjustments to the master cylinder push rod correct? Or possibly the pressure plate?

To me the fork looks way too far forward if the clutch in newer. I think you have an issue inside the clutch itself. Bolts on pressure plate loose, Clutch problem, Bearing not all the way on the bearing sleeve ect.
