Hi everytone, I need help on this.
This is my problem, i have 2005 s2k 70xxx miles. Recently Ive used 110 leaded octain( i have diff exhaust so im not worrying about cat) I only filled 3 gal on almost empty tank.
Recently this happaned, while i was still on 110, i WOT from first then got into 2nd gear. I preaty much had to time and i had to switch to 3rd, 3rd gear did samething., High RPM, car is barly moving, ( I have 3k miles on my clutch, Exedy clutch) also before this started happaning i had clutch adjustment, (one guy adjested my clutch pedal, after he adjusted it I dont have to press clutch all the way in to shift trough gears anymore( this guy has a lots of RIght hand sided cars and he does a lots of tunning of JDM cars.
Car is not smoking it runs fine accepet that slip when getting into high RPM,
Could this be related to motor , since ive used 110,
or the clutch adjustment.???

 

If the clutch is slipping it sounds like it just needs adjusting based on the fact that the clutch only has 3K miles on it.. check the pedal adjustment first..

 

See the thing is I can hear motor going up rpm and then droping rpm sound comes in even though im holding gas down all the way (like the motor has mind of its own. It only does it when in gears, hen In N its revs fine/. I had slipping clutch before , and it didnt sound like that ..

 

I'm not sure if it's such a good idea to not fully depress the clutch pedal.

 

he adjusted that way, i guesss too high, so thats what he told me, I assumed he knew what he was doing , since he had all those cars he workes on and mod them.

 

You should almost never have to adjust a hydraulic clutch system. There simply is no need. The system adjusts itself as the disc wears. By doing an "adjustment" you have a better chance of messing something up than if you left it alone.

 

Do you have any free play on the peddle? If not, that is you problem. You have to have free play or the clutch pressure plate isn't fully seated on the disc and flywheel and it will slip under load. Good way to burn up a clutch and spend a lot of unnecessary money.

If the peddle has free play, then I would look at your CDV as the possible culprit. This really should be removed if you haven't done so yet.

 

The reason he did adjusted Ive been having problems with my clutch, WHen i WOT the car my clutch would noticably get soft, I have to pump it like 20 times to get it back to have preasure, and recently my clutch got really stiff, I had to press it hard on the clutch to get in the gear (Ive changed master Once and slave 3 times, still same problem,
Peddle gets soft after beating on the car, Thats why I went to that guy to take a look why its doing this crap, So he adjusted the clutch after that I started having probles with slipping, but no more soft peddle after he adjusted it, so what should i get soft peddle when beating on the car, or slipping . :S

 

this.

did you bleed the clutch fluid after you changed the cylinders? sounds like there could be air in the system as well.

 

There is only ONE correct setting for the clutch rod. It is not adjustable, but settable (meaning you should not adjust for preference, only adjust for correct setting)

If it is set improperly, the clutch will not fully engage with pedal release and you will get the results you posted.
