hello

i blanked the egr valve off yesterday on my mondeo 2 litre tdci its an 03 reg

on a 40 mile round trip later i noticed a whine coming from the engine and it seamed like it was as i set off from stand still and truning the wheel .

when i got back home i looked under bonnet and found power steering fluid been leaking this only happened since i blanked egr valve off

anybody any ideas why this is ?

thank you
