Why I also want to be there when they are replacing the clutch is to check what caused the problem.
I think it is maybe a bad presure plate or as you have mentioned a leak from my gearbox seal.
Although I have peeped into the inspection plate to see what is going on inside the bellhousing but there was no oil.
It can also be so little that it does'nt drip to leak out but be absorbed by the clutch plate.
Only taking it apart will tell the full story.
Any hints on the flywheel? It was skimmed when the previous clutch was installed.
It is also possible that they did a crappy job of it.
This is all the reasons why I want to be there when they install the new clutch kit.
I do not want a crappy job again.
