Sticky: (Official) 370Z Clutch Pressure (CSC) Failures

ColdFire

I had a failure i'm not 100% sure but Joe@Zspeed said it could be CSC and i'll explain why.
My car been sitting a year under a cover with battery disconnected since i'm away and i have trust issues handing over my 370z key to ANYONE .
After doing an oil change i drove my car around for a day or two and i noticed my clutch pedal feels spongy. It happened to me before and after driving for a while it goes back to normal usually. I was like " Yea man it's not a biggie"
Anyway after driving for few hours the pedal feel got super spongy and it won't go into any gear! I parked it waited for 15 mins then i tried slamming the knob into 2nd and it did. Kept driving home and got on the phone with Joe@Zspeed and he suspect it's CSC failure.

Ordered Zspeed CSC, Clutch and Master Cylinder. I'm still waiting for my parts to arrive from OH to Qatar... Shipping is a pain in the a$$. When you live 8000 miles away from the source.
After doing some research i've seen that symptoms of bad CSC would be leaking of clutch oil. Upon inspection the Master Cylinder seems to be above the max!! so i have oil for sure. I kept checking underneath the car everyday! I don't see a single oil dot.

However, when i turned the car on today to keep the battery charged. It seems that it engages in all gears! IT HEALED IT SELF! I haven't driven the car yet. since i ordered the parts. But what could it be? Any clue ? Could the system oil had boiled and it had air and now its fine? Hmmmm it's very weird indeed. I hate to take my tranny off if an oil flush or a new master cylinder could be the fix.
I've been thinking.... Letting your car sit for a year could mean that my clutch oil absorbed water and got contaminated. That's why i got the spongy feel and that's why my clutch fluid is above the max mark. is that possible?
