Oil leak I have a Renault Megane Schenic 1998 RT Auto.I noticed that a rubber pipe on top of the gearbox was not connected (look like a breather pipe) The moment I connected this pipe the car developed a oil leak. The oil is coming from the engin and not the gearbox. Is there a connection between engin and the gearbox with this pipe? How can I fix this? Thanks Pierre

In auto gearbox cars there is connection between gearbox and engine. what you connected is a vacuum pipe to vacuum capsule,it for gear changes, it seems it faulty.

Hello Pierre,
A little more detail may help me on this one, however this sounds like possibly your power steering pipe? both these use auto trans fluid it is reddy brown in colour and viscosity (Thickness) watery.
If this is the pipe, check the fluid reservoir it should have either a Yellow top with power steering or a steering wheel diagram on it.
If full then please give me more information as to location on engine where pipe comes from and goes too as nowadays engine oil is usually internally dispersed. Only oil cooler pipes possibly? will go to a finned type radiator usually near the front grille of the vehicle.
I hope this points you in the right direction as I'm thinking of giving this help up as very hard to remain on top slot when loads of questions responded to and no replies.
Good Luck,
Paul 'W'
