Another CSC failure?

Indeed, it sounds like a good alternative to a + $2000 dollar replacement right now. Since FI is far into the future, the present might be a great time...

It is sitting at a Nissan dealership, so I will find myself some good fluid and carefully supervise to ensure they actually use it. Maybe they won't charge me some exorbitant price for the service.

Also, now I'm going to feel very bad about this, but the car is over three years old and has not once seen a clutch fluid flush. Hopefully, this will alleviate the problem.

Are there any alternatives to RBF600? I'm trying to source the stuff locally but the longer the car sits, the more work I miss. I have a special circumstance, so don't worry about the whole work thing.

EDIT:

By the way, I just called the dealer and asked for how much it would be to bleed and flush the clutch fluid. 145 dollars. I laughed in their face and they hung up.

I'm also having a hell of a time trying to find some brake fluid that isn't some generic Autozone or Walmart crap. I know Nissan uses Motul fluids, but only for sponsored racing. The closest place is 45 minutes away and they're actually out of stock.

The best stuff you can find right now at Autozone is Vavoline Synthetic brake fluid. It is actually pretty decent and cheap, has as dry boil point of 480F and a wet of 311F. I use it in all my non-track vehicles, I'm sure it is better than what is in there now.

I would also put the clutch spring back in, either stock or the lightweight one. You can have my lightweight one if you want, just pay shipping & handling.

I have since replaced the stock spring, which is kind of odd because the clutch pedal can't even fully actuate back to its unsprung position. I would actually like the lightweight spring, if your handling doesn't include a biochemical fuel charge for your food!

But it does look like the piston could and likely would be causing this problem. Its most odd because the fluid reservoir shows no change in level (right below max). I would think if the CSC failed, that the fluid would drain/leak, but I'm showing no change, which also leads to me to think the CSC failed because the fluid isn't the issue.

yep, i think it's your piston so fluid change will net you probably nothing... thus i think you should have the dealer replace the unit and bring her home.

The pedal sticks down if there isn't sufficient hydraulic pressure to return it. Definitely sounds like air in the system. Now the reason the air is there is because of 1 of 2 things, either the fluid boiled due to fluid contamination that lowered the boiling point, or air entered the system somewhere. The later seems unlikely at this point as if that were the case then fluid could also leak out the same place.

Just bleed it, takes all of 5-10 minutes. Takes more time getting the car jacked up to get access to the bleed screw.

Bleeding isn't a bad idea. If anything, worst case scenario would be guaranteed, so I might as well take half an hour and bleed with fresh, 10 dollar fluid than dismiss it immediately as CSC failure.

I do not know if this post should be here or not but here goes.

I just changed my brake fluid to DOT 5.1 and had some left over and changed my clutch fluid. It was black and looked like it had well over 13,000 miles on it.
