Oil weeping from air intake pipes
I have oil weeping from the air inlet pipes as they cross the engine and drop down the back to the turbo. Car is a Euro 5 D5 205. Air filter is clean and there is no smoke from exhaust. Slight whine under acceleration. I have searched and searched but cannot see anything on this. I assume that these still have a PCV system. There is a box connected to the duct after the MAF and before the weep, tried to remove the duct yesterday when doing the timing belt but had to leave it in place due to this box. Seem to remember it had a 15 or 20mm hose into the bottom and if this is an oil trap, makes sense that the oil is after this. Has anyone got a diagram showing the parts, can barely find a picture of my engine let alone any tech info. Any idea if it has a PCV valve and where it is, not done a glove test yet....
