Hi peeps

Wonder if anyone can help. Got what I think is an oil leak on a vec 1.9 cdti 150. When coming to a stop I get a smell of oil throught the vents.

I got under the car and it looks like oil is leaking from the pipe into the turbo. Similar to the first pic in this link but not half as bad http://www.vectra-c.com/forum/showthread.php?t=111733

I have tried to tighten the circlip but cant get to it. I have not taken the heat shield off so im not convinced its coming from the pipe into turbo.

To get at this lot properly can anyone give any advice? Will it be a case of removing the bumber and rads to get into it? Would it be worth checking the intercooler isnt bust either.

Any advice would be good
