Arrgghh Clutch slipping
Discussion
I changed the clutch 1 month ago, now the cluth has started to slip in 4/5 gear. should i have changed the whole thing (only put in the plate) Could it slip because of oil. Any advise.

Mikael,
Personally, I would always change the friction disk w/ the pressure plate, but many argue it isn't necessary.
Question, did you use a stock friction disk or an upgraded one? Also, did you remove the flywheel and have it trued, balanced and re-faced? I'm guessing there's a strong possibility you didn't, because this is exactly what happens when you fail to do so.
Also, how easy where you when braking in the new disk? You really shouldn't 'Get on it' for 500 to 1,000 miles to insure that friction plate and flywheel properly bed-in with one another.
My guess is that you'll have to pull the flywheel and have it dressed. Be sure to look for any 'Bluing' on the flywheel, if you find it, you're looking at a replacement, because it has heat tempered and will not hold a dressing for long and could shatter (Very Bad!!). Hope this helps. Happy Motoring! Jim'85TE

Jim is very correct. Whenever the clutch is done the flywheel should be turned {refinished} to make the mating surface true and correct. If the flywheel is warped in contact area with the disc, that would be the cause of slipping which will result in the disc wearing unevenly and produce a chatter as well.
Hope this helps,

Mikael,
I forgot to address your queery regarding slippage due to oil. The answer is yes, if any oil got into the bell housing, the clutch disk material will absorb it like a sponge causing it to slip.
This is a very remote possibility as the only way oil can normally get in there is if the rear crank seal failed, allowing engine oil to enter the bell housing (I had mine fail within the first couple hundred miles after I replaced my clutch, but, fortunately it wasn't a total failure and the little oil which did seep through was thrown by centrifugal force to the outside of the bell housing interior and away from the clutch disk). Or, the sealed bearing in the front of the box failed allowing transmission fluid to enter the bell housing from the rear.
If either of these occured, you will have to replace the clutch disk as it would be impossible to clean/extract all the oil which it would have absorbed. Also, you would have to clean the interior of the bell housing completely as well as the pressure plate and flywheel. Why do you suspect oil as the culprit? Hope this helps...Jim'85TE
