hey you amazing people..
i need your help.

I have a
1997 Honda Civic LX
5spd manual
CAI

Before you read (its a long story) heres the short version:
Had problems witch clutch, changed it once had problems, and the 2nd clutch has the same problem. After the clutch warms up it slipps... when accelerated the car simply REVS (from 2rpm to 5rpm without gaining much speed and when throttle is let off it goes back where it belongs 2rpm)




Here's the story...

I bought the car about 3 years ago at 110,000 miles. I drove it for a year and started having some problems with the clutch. Sometimes when i accelerated it felt like the clutch was slipping, and the RPM's would go up but i wasnt going much faster, as soon as i let go the throttle it would go back where it belongs. (Ex. 5th speed at 45mph and 2000 RPM >> floor it >> 48 mph at 4-5000 RPM >> Let go of thottle >> 50 mph at 2200 RPM )
so yeah, i took it to my mechanic, he said i need a new clutch. Told him to buy one, and ill bring it in for a clutch change. After he changed the clutch, the same thing happened but within 4-5 days of clutch change... so i took it to him, he check it out and said its not the clutch but just for the sake of it, he went and bought another clutch (a higher perfomence one) and installed it. i drove the car for about 3 weeks with no problem... untill it started doing it again.

So we put in a new Presure Plate and flywheel, Master Cyl and Slave... he changed EVERYTHING. while he put in the new stuff.. he also took the clutch down to look at it.. and he said there wasnt any damage or anything.. and it should be working fine.

worked for about 4 weeks.. untill it started doing it again.. and this is where i am now.

The wierd thing is this...

In the mornings when its cold.. and the car is cold the clutch works perfect, nice and smooth. As soon as the car warms up and the clutch, the clutch stiffens from the half way down... and it only catches at the top. and when accelerated the clutch "slips" and it rev's up without going much faster

so i took it my mechanic.. he said that in 10 years that he's been a mechanic and changed clutches.. this is the 1st one he has problems with.
So he told me to go get some other opinions beacuse hes out of opinions and the next thing is to get a new clutch + pressure plate and install it.

So i went to Firestone and i gave the ppl the car and it took em 4 hours to look at it (3 mechanics looked at it) and said that the problem is the Master Cyl and Slave but i called my mechanic and i gave em the phone... (beacuse the master and slave were changed a long time ago beacuse of leakage.. so that leaking was old)...

they had no idea what else it can be either.

so im trying to see if anyone heres had any opinions.. i might it might be something really stupid and easy... but i dont know..
so please tell me if you have ANY idea.
