Clutch Disc/Flywheel "Welded" Together... Maybe?

Clutch Disc/Flywheel "Welded" Together... Maybe?
So I have been driving my car for about 4 months now without any problems. I go out last week to drive it, start it up & it won't go into gear. I figured the Wilwood Master Cylinder I had went bad because the peddle felt weak. I installed a new Wilwood MS today and the peddle feels great. It has constant pressure & feels stiff but still won't go into gear while the engine is running.
I'm guessing now it is the Slave Cylinder... I was hoping it wasn't since the part is only 4 months old now. Is there anyway to test a SC on the car? If not I am going to have to pull the engine/trans just to replace a $100 part.

You're convince it's not a bleeding problem, so go ahead and replace the slave.
If the master has no external leaks, is new and the system is bled, then the trans. should go into gear w/ engine off as well as engine on. If it wont' go into gear w/ engine on, then the clutch isn't releasing.

Car goes into gear fine when the engine is not running & I dont have any leaks at all...
JMD... you got me thinking today about the "clutch isn't releasing".
The night before I parked my car literally 5 mins before I parked it... I was giving it hell destroying(two times) a new nissan 370z. I have a RPS Stage 3 & CYN-R-G Segmented flywheel... Could it be possible that I heated them up enough for them to "weld" themselves together when it was cooling off?
That would explain why my clutch felt sloppy but about half way down it felt almost normal...

It is possible to weld a disc to the flywheel and/or plate but this only occurs under extreme heat. You physically have to begin to melt the disc for this to occur. The only way to know if this has happened is to pull the trans and the clutch and take a look. Let me know what you find. If you have any questions I will be happy to assist you. Thanks,

What sucks is I have an LS1 in a 93 RX-7 & the trans is a really tight fit. I found out yesterday I can pull the trans leaving the bell housing attached to the motor. I really thought for a 2 days I might have to pull the engine/trans to take a look.
I read in another thread it might be possible to break them loose driving the car around & rev matching with the clutch peddle pressed in. Doing some highway pulls in 5th & 6th...

I think I have an idea im going to try tomorrow
1. Put the car on jack stands
2. Start the car in 2nd Gear so the car starts moving.
3. While the clutch peddle is pressed in.. slowly pull the e-break
4. While pulling the e-brake, press in clutch peddle & floor the gas.
Would pulling the e-brake break the clutch disc free from the flywheel since the clutch disc rides on the trans input shaft? And the input shaft connects to the driveshaft... driveshaft connects to diff... diff connects to axles.. axles to the brakes...

If you have in fact welded the disc to the plate or flywheel then you may not want to ****** it apart. You will have material deposits on the surface that the disc stuck too and this means that you will likely see more agressive wear in this area in the future. You can also further damage the disc by doing this. It is certainly your call if you want to give it a shot. Good luck and let us know what you find. Thanks,
