Have a look here first http://www.omegaowners.com/forum/YaBB.pl?num=1256423727 as a starter as to what could be causing the leak.

i did follow that thread - but if it is oil mist from the ,turbo as described. how is that cured ? clips, pipes etc i,ll check but it,s the initial cause i want to cure.

hmm,
 ive had a look at the other thread and see someone mentioned oil cooler pipes which is the usual one for these, cant see it being from the turbo if its on the ns of engine bay? the oil cooler pipes run down the ns and into the cooler which is at the front of the car behind the vent in the bumper so thats a definte possibility if you say its all over the rad,? but if its the back of the rad the cranshaft oil seal is also a possible cause of it, is it defo engine oil? cos fuel injector pump is nearside  and diesel thats run down could well look like engine oil?

i waited whilst it got dark purposely so i could shine a bright light to try & source of leak - black plastic o/s jubilee clip n/s both jubilees that go to egr show signs of leakage, does that indicate turbo? - no oil on front & sides of engine as previously indicated. rad cowl covered.

Assuming that the black plastic charge-air pipe (embossed 'Turbo Diesel') is intact, then fit a new connecting hose from it to the EGR valve, plus two new jubilee clips.

Hose is part no 90467872 - around 14 quid from Vx.

Thoroughly clean out the charge-air pipe at each oil-change (every 4.500 miles absolute max).

As previously stated, the root-cause is oil mist from the turbo, and I've yet to see a turbo-diesel engine that doesn't have this characteristic. So long as it's not blowing out a significant quantity of oil, (and you're not getting blueish smoke emissions), then this method should suffice. Thereafter, just keep an eye on it.

By the way, ensure that the air filter and induction system is also scrupulously clean too.
Your filtration must be 100%.
