Alright guys, so I've had an on going problem with my clutch. (94 Acura Integra RS) When I've been driving for a good amount of time, 20 mins or later, or when it's hot outside. I live in Tucson, AZ so it's always hot, and now that it's summer, it's been happening more frequently. The clutch won't engage the gear, it acts as if it's in neutral, the rpms spike, but the car doesn't move. It happens in any gear. To me it seems to engage the gear half way, and if I push the gas a little more the rpms will spike, and I won't accelerate. With that being said, I've noticed the clutch pedal gets harder to push when the problem occurs.

Also, when the car is cool, or when it's a cool night. The clutch is fine, play in the pedal, the clutch engages the gear, no problem at all. Slowly, the pressure will build up if I drive for a good amount of time though.

I need some help, suggestions, advice, anything. I've tired bleeding the clutch multiple times, it helps for the moment, but slowly the pressure builds up. I've adjusted the pedal, and the MC multiple times, doesn't make a difference. I've bought a new MC and SC, and I have the same problem. The clutch is the stock original clutch from 94, so I was thinking it might be the clutch going out. But if it was the clutch wouldn't it be happening all the time? Not only when the car is hot?

Anyways, I'd appreciate any help. Thanks.

 

Sounds like your clutch is slipping aka worn. replace it and the master/slave as well they arent very expensive. I found myself its best to do it all at once, that way you know its new and when you did it.

 

Sounds like a slipping clutch. Just like fading brakes, the friction material will slip more when it reaches past a certain temperature.

Lucky for you, Exedy KHC05 clutch kits are like $112 shipped.

 

I agree, it sounds like a clutch problem, more so if it is indeed the original stock clutch, it is 20 years old.

Either way you have replaced and done everything else MC, SC, bleeding adjusting, and it is definitely time for a new clutch anyway. 94
