Clucth pedal sucking to the floor

[evildave32]

So i am new here and have searched through lots of threads to figure out my problem with no luck.Everytime i rev my engine the clutch pedal will suck to the floor and it seems like the stock blow off on my rb20 doesnt release any pressure whats wrong?

LOL, what????

So let me get this straight. You rev your engine (of unknown type in an unknown chassis) and your clutch (of an unknown type) moves from the normal resting position to the floor? Considering the two systems are not connected...........................

Ya know what, screw it. I'm gonna let somebody else handle this one. I can tell you are just going to give me a head ache. Please include car type, engine type, who did the swap if it is a swap, etc. to help somebody else answer your "questions". I'm not even going to start on the BOV not making enough noise.

Sorry for not including enough info on the first post . I have a s13 with a rb20 swap.Swap done with the help of some friends,harness done by Mr Carl H(minus a couple tech things for the fans and fuel pump)Stock everything (including clutch).Installed new clutch slave and master, bled the system no problems till now. Its not that i am asking why no noise Cjmartz2k its just the recirc valve seem to do its job till today . I went for a drive noticed no sound of recirc valve and the clutch just sucked to the floor pull it up to change gears and it sinks again.I know i am a noob at from what i have seen we are not very welcome by some people on this forum, but upon following the advice i have seen to search through threads here to resolve the problem as far as i could fine there are none concerning the problem i am having, there for the initial post. Once again sorry for not posting enough info. But if anyone could help me with a fix it would be very much appreciated.

Much better info. Does the pedal give any resistance after you pull it up than push it again? Fist check the fluid level in the clutch master cylinder. Second, look for leaks around the slave. Third, bleed the crap out of it just for good measure. Look to see if the plunger is moving in and out of the slave. If no (or not enough) you are lucky and it's either a leak, back master cylinder, or bad slave. If that arm that the slave pushes on is floppy with no resistance, you'll likely be pulling the transmission. The revs can in no way effect the clutch pedal other than vibration which leads me to believe you have zero resistance from something in the system. For the BOV, check your vacuum lines. Has your idle been acting funny lately?

Yes once you pull the pedal up it will hold a little pressure till you change gears again then right back to the floor it goes. Plenty of fluid in the resevoir upon closer inspection(aka crawling under the damn dashboard) the clutch master is leaking at the back down the pedal, so to the parts house i go to get another. If this fixes it i feel stupid but thankful.thanks for all your help Cjmartz2k and i will let you know if this works.

If it's leaking there, it's 100% the master. Should be an easy fix, and good luck!

[evildave32]

100% fixed it was the master after all thanks for the help hopefully i will end my noob status soon but until then i appreciate the help.

Good, glad you got it fixed I'd check the vacuum lines again for the BOV.
