I have mounted the bi-masa clutch in my Peugeot 307. The car cluts what happens to it is that when I remove the foot of the accelerator, when the fall makes the engine observed that it makes a noise as if they touch the teeth of some pine nuts. The peculiar is that the clutch is a little peak and it does not sound to it, until I step on it again to change their gear and it returns to the fall of the engine at low revolutions.
Hello, it can be that they have not filled the change with oil when reassembling it again, and what you hear are the pine nuts "touching", it is a possibility, check the level of the box before using the car (it is a advice) greetings !!!
