Morning just been out to check my cars levels and noticed once again i have a oil leak coming out of the breather pipes at the front.(i think thats what there called) I have had the plemnum taken off and cleaned twice now in the last 3 months. When the mechanic did it the last time he said their was a lot of water in the bottom of the breather pipes(that silver thing at the bottom) He said the engine could be running over pressureised. Just a couple of things that help somebody diagnose my fault no water loss that i can see. havent needed to top up. my back box blew up on the m40 the other day.I dont know if any of this helps but i no nothing about car engines.. Sorry for the long story but trying to give as much details at poss.

Sorry have tried to put a picture on but cant.. If you mean look at the front of the engine you have two big black pipes that go down into a silver u shaped housing.
