The troubles continue : Clutch & Leak

I really wouldn't like to be posting this much, about my troubles at least.

Well got the car all up and running and everything was great. I did however notice, right after WOT I had a strange sound coming from right infront / under my feet that sounds like driving on a gravel road. I really haven't pushed the car. Maybe a couple hard pulls here and there after I heard that problem initially.

Two nights ago while driving on I-4 I gave the car a little gas to overtake and my revs just jumps and then slammed back and grabbed. Did this a few times. I relized it was my clutch, but when I got home, my back hatch was covered in a lubricant. Don't think it's motor oil as it seams thinner. I know a little oil can make a big mess but I am assuming it is the trans.


I'm going to go ahead and upgrade the clutch to a stage 2+ and add a lightweight flywheel.

My biggest problem or concern is where is the leak coming from? I snooped around best I could under the car and everything just looks wet.

Any help would be great. TIA

-Nick

Nope. CV goop won't make it to the back of the car. I'm afraid your clutch slave has crapped the bed. On the front of your trans case is the clutch slave, which has a rubber bellows on it. is it moist with hydraulic fluid? There's your leak. Now, buckle up for the little slice of hell bleeding that sucker. Hint: you'll need to detach the master.

BTW, unless you are fighting for 10ths of a second on the Auto-X course or drag strip, I would recommend a stock clutch (or Valeo flywheel conversion) over a performance setup.

If I am lying under the car, will the slave cylinder be on the lower portion of the trans? In clear sight? Because I do see that and it is wet. Unfortunately most of the trans side of the car is. What is odd to me is the pass drive axle and power steering up were covered as well. Along with the oil drain pan. With the slave cylinder going would it get all the way up there as well?

Get a power bleeder.
Motive 0100 European Power Bleeder Kit : Amazon.com : Automotive Motive 0100 European Power Bleeder Kit : Amazon.com : Automotive

Make yourself a compression tool like in this video.

Consider replacing the hard supply line at the same time.
Bleed the slave before you mount it to the tranny.
You'll be fine.

That's very informative, thanks man. Seams pretty straight forward. Luckily I have the bleeder from my previous audi. Works great for me then. Just want to be 100% and make sure that is the problem.

The odd thing is I can actually still drive the car fine, other than the loss of fluid and the slip at higher rpms the car acts as it should.

Unfortunately, bleeding these clutch hydraulics is not straight forward. Search for the proper technique, it's been discussed a few times. Take your time and be patient, because patience is something you'll need a lot of.

I'll have to disagree that the clutch hydraulics are your problem. It sounds like you have a bad rear main seal or trans input seal. If the oil gets onto the clutch lining it will cause it to slip. I can't imagine how hydraulic fluid would make it into the bell housing and a hydraulic leak alone will not cause the clutch to slip.
The smell of the leaking fluid should be a telltale. Trans fluid has a very distinct sulphur smell. Motor oil is more fragrant than brake/clutch fluid.

It is trans fluid, Im almost 99.9%

I did tear into the car a little today and the clutch slave cylinder has **** the bed. It has developed a crack/tear and is covered with fluid. Since the clutch is ran off pressure I could see how the slave cylinder could spew under the car and spray the effected areas. I'm about half way in dropping the trans but I'm headed to dinner. It appears to be my throw out bearing or return bearing is grinding as well. Either way a new clutch is going in. Just have to make sure the other seals are intact and it is just not the clutch slave.

Well, finally got around to getting the trans completely out. It was worse than I thought and sets me back so much. What I'm assuming happened is the throwout bearing failed, causing shrapnel, which gashed into the trans case, caused the leak which made the clutch slip. Pics of the massacre

Ouch!

If you know someone that can weld aluminum they should be able to plug it for you or use the good ole jb weld patch on it.

Where abouts in Orlando are you?

I'm towards Daytona, in DeLand. So our trans are aluminum? Or are they cast?

I'm probably going to end up jb welding it. I just want to make sure it holds.

Zingo... Check your private message box. I recently did my clutch as well.

Can you post a picture of what was left of your throw-out bearing?

I saw another post where a hole was poked into the casting and the poster used JB Weld and some window screen to make a patch.

I'm not sure I would trust JB to repair an area that is so difficult to re access if it doesn't hold.

My throw out was come rely disintegrated if I can figure out how to post photos from my iPhone I will.

Here's the throw out bearing. I trust the JB. I've used it before at different times, I got the industrial type, high psi & temp. Shouldn't faze it. As there won't be anything grinding or rubbing on it

It looks to me as if just the plastic/nylon portions of the throw-out bearing disintegrated, and I have a hard time agreeing that it would be sufficient to puncture the bell housing portion of the transmission.

The piece in the middle of the bearing and bottom washer is half gone. Which in fact is metal. There was metal shards that have been rounded and were in the bell housing. They did not come from the transmission and I couldn't find anything wrong with the clutch, pressure plate or flywheel. Other than the fact they all have been peppered from the metal.
