Don't know if anyone's noticed this "problem" but when the clutch fluid reservoir is up to the "full" level on my car and I replace the rubber moisture barrier and cap the reservoir becomes so full that it overflows slightly.

If I remove the cap and moisture barrier the fluid appears too low/on the add mark.

It seems to me that the rubber moisture barrier is too big as it takes up all the available space in the reservoir. My question is this: Would it hurt to do without the moisture barrier, fill the reservoir up to the "full" mark and reinstall the cap?

Has this occurred to anyone else or am I trying to get rid of something that does a perfectly good job?
 
I was thinking the same thing with mine - I just filled to a "happy medium" - Hope that is correct as I was told it is next to impossible to get it "right" w/ the rubber barrier installed :(
 
Clutch rubber moisture barrier

89x2, do you reckon that rubber thing is really necessary (sounds like a post for a different kind of forum!) Did you think about running without it?

Obviously Chevy put it there for a purpose but with the cap only surely that would give as goos an amount of protection as the brake fluid reservoirs get?

This might seem a bit like a petty post to some but there just doesn't seem to be much fluid in there - or maybe I'm worried about my recent investment in a new Centerforce clutch?!
 
I think the little rubber thing is a necessary part in helping with moisture control. MTCW.

It does make it harder to fill and control the fluid level. Real PITA stuck back up in there.

You DO need the rubber moisture barrier

Actually I can see why you can't be without it now, there's a small hole in the cap that I didn't notice before so it wouldn't be a good idea to be without it. The rubber must be designed to take up all the available airspace.

Guess that's why engineers take so long designing a car, and all we have to do is drive it!
 
Here's what to do.
Fold the top hat up into the cap.
You will notice that there is now plenty of room for the fluid and the cap will still work without leaking.
 
Trrgod has it right I just went through the same thing 2 weeks ago. Just collapse the rubber like a top hat. After you have filled the reservoir insert the collapsed barrier and screw the cap back on. You may get a little spillage so place some paper towelling below to catch it.
