Loss of power between 1000 & 2500 revs - Mondeo 2ltr diesel 02 Plate

[dickeygreen]

Hi I wonder if anyone can offer me some help, I have a 2 litre diesel mondeo and over the last few months we have had a problem with loss of revs between 1000-2500 rpm.

Today after a long run I lifted the bonnet to find a lot of oil around the engine and other parts, however I cannot for the life of me find out where it's coming from.

Before I take it into a garage and part for them to look and fix I was going to see if I could do it myself and save me some money as well as learning new things :)

I've changed one of the pipes before that had a split in it and was giving loss of power at the top end.

But as I say I can't see where this oil is coming from and it looks likes coming out under pressure as it's hit the underside of the bonnet.
