Car caught on fire...now clutch is slipping!

This has been the worst week of my life! First I got the clutch put in and the slave cylinder broke, then I was getting SFC's put on today and the welder melted a fuel line and my car caught on fire (only for about 20 secs) and then tonight when I'm on my way back to school my BRAND NEW 200 mile old Spec II clutch starts slipping! Could the line going to the slave cylinder have got burnt or something? I haven't had a chance to get under the car and check everything out since the fire! Could that make my clutch slip? Any ideas?

If the line was damaged and had a hole in it or soemthing you would not have any pressure in the clutcha and you wouldnt even be able to change gears or anything. It would cause a problem disengaging not engaging.

Dont know what to tell you.

Good luck.

I just went outside to check the slave cylinder to see if it is ok and it's feels kinda loose and is leaking a little bit of fluid around the bottom! Also is the Steel braided line supposed to be loose fitting?

if its leaking fluid then its bad. But the bad slave wouldnt make it slip.

The steal braided line sould be able to spin on the end, dont think it should feel loose though.

the res is held in by a plastic push pin,so a little loose is ok.the line is like a quick connect setup but is held on by a rollpin pushed in on the side,no roll pin the line would just fall off!i'd say the clutch slave was not bled good enough!when i drilled out the restriciter in the clutch line(slave mod)it took me hour's to bleed!

Could you explain this mod and tell me what it does?


Not having the hydrolics bled properly or having faulty hydrolics would not cause the clutch to slip. When the clutch is engaged the hydrolics are not in use, therefore it doesnt matter what kind of condition they are in.

Now, if you have problems getting the car into gear for example then you want to look at the slave and master cylinders and make sure they are bled and in good working condition.


Something like oil getting on the fly wheel or a finger breaking on the pressure plate could cause it to slip.

Sounds to me like some of the fluid from the master/slave leaked onto the clutch disc making a slippery surface causing it to slip. I suggest maybe replacing the master/slave and pulling the tranny and cleaning the whole flywheel & clutch assembly.

Well the slave cylinder is only 3 days old as the old one broke when we put it back on! I drove the T/A a little bit ago to get something to eat and it isn't slipping anymore! What would cause it to slip for 80 miles then just stop? (I hope it's stopped)

Somethign could have splashed or dripped onto it and then worn off.

Did you usea pilot bushing or bearing when you put the clutch in? If you used a busing maybe it was over greased? Driving on the highway could have caused it to heat up and then some of it was slung out onto the face of the flywheel? Then it wore off and it stopped slipping? Just a guess.

So as long as the fire didn't have anything to do with it that's fine! I'm going on another trip today so hopefully we will see!

It slipped ever so slightly tonight but nothing like last night! Hopefully all that grease (if that's what it is) is almost all the way gone now!

I'm going to be doing the clutch this winter and remember reading about the pilot bearing opposed to the bushing a while back. Is the bearing much of an improvement and what is the part number and where can I get it?

thanks

Using a bearing or a bushing is just preferance. When i did my clutch i was going to use a bearing, but when i went to autozone to buy it the bearing looked really cheap and i didnt have a good feeling about how long it would last so i just did a bushing instead. The cars come from the factory with a bushing so thats what i ended up putting back in.

Bushings are simple and you dont have to worry about little needle bearings falling out of them or anything. if you run a search on the bearing vs. bushing you will come up with mixd results, just do what ever you feel like doing.
