Ok, here is the deal.
I hate mini's, but i'm stuck with this one.
If i had known the crap this car would do
to me, i would have bought a more reliable car,
.....like an MG, lol.

Since I bought it:

1) Blown Engine. Going down freeway at 71, and engine light comes on yellow
and 30 secs later it goes red, and then engine winding down to zero. 2 years ago, Fixed with new engine.
2) Fuel leak from Plastic,.."Plastic,Really!?"... fuel filter canister at the top, of elbow.
3) Key Error icon even with brand new 150 buck key, everyday, even before i get in car.
4) Light bulb error icon, even though I've replaced every damned bulb in car.
5) Window seals flying off in the wind and at car washes. The seals aren't req, but car looks ugly without them,
so i have to keep buying clear rtv sealant to reattach them. Didn't they do hot weather testing?

FINALLY, I have my clutch just go to the floor without any warning, the other day.
Takes me a day of web surfing to find the likely cause. A Slave Cylinder for the Clutch is supposedly the cause.
I get on the phone, with autoparts places, and everyone of them gives me the one for 2003 to 2006 mini coopers,
in a box marked as a 2008, and its definitely the wrong part. I find the right one, in all places, Amazon.

I am going to install said part, tomorrow. I have but one question, before i install it.

Does this Slave cylinder have a small little oring, i have to put in?

The videos and advice are all geared for 2003 to 2006 slave cylinders, but mine is different,
and i don't see any o-ring on either the line, or old slave cylinder, and i don't see one in the new part.
If i can get size and specs, i can simply get one somewhere, but man, are 2008's on some sort of no info internet ban?
So hard to find anything.

I know this is a long post for a simple question, but i need anyone reading,
to understand my frustration. Thanks for any help.

 

Can either be clutch slave 21-52-6-770-600 with clutch hose 21-52-6-770-598 or clutch slave 21-52-6-798-372 with clutch hose 21-52-6-783-623 superseded by 21-52-6-863-945. Let me know if you have any questions.
