I live in Colorado, and it seems every winter when it gets below freezing over night, the next morning my clutch pedal hits the floor with no pressure. You can bleed the clutch and it works ok for a little while, then it loses all pressure again.

The master and slave cylinder are not leaking, and in fact have been replaced by either myself or the dealership every year.

I was out bleeding the clutch system again yesterday and was taking a better look, and with the bleeder valve closed, some pressure in the line, and the lid on the resevoir on, everytime the pedel was pushed some fluid would spill out from under the lid on the resevoir...

I cant imagine this is normal, nor can i see how this would allow air into the line (although id be happy to accept that im wrong on that because i honestly dont know)... It almost seems like there is maybe a blockage in the hard line??

Can anyone please help me diagnose this? I could just replace everything but id rather not spend a couple hundred bucks if its just the line or maybe a faulty resevoir or something.

Sorry this is long!
