Default Oil in throttle body

Hi to all. New car brings new issues. After working on my 2005 307 1.6 today I noticed a lot of oil around the pipes connected to the throttle housing. Oil was coming from the two below and one above. I removed the housing and have given it and also the attached sensors a clean, cleaned the pipes too. The upper single pipe has not split but the inner lining has perished quiet bad. I'm new to this problem but wondered if 1- the oil should be there ( I'm guessing not) and 2- what the upper single pipe is refered to so I can order a new one. I've rebuilt it all and tightened the jubilee clips as they too were very loose. Sorry about the essay
Many thanks in advance

The large part is called an 'air doser', looks to be part number 0345E5
The smaller part looks to be a 'sleeve' part number 0382NY

Don't quote me on that i would need your vin number to verify.

The larger part retails at around 220 on ebay so before shelling out make sure it's the source of the problem, a lot of money to pay out if it's not.

The air Doser on the 1.6 is well known for leaking oil. It's normal to have a little bit of oil there. Some people have has success with sorting the leak by simply using black sealer. I would give it a clean, refit, drive for a bit and then reinspect. Hopefully you'll find that only a little oil have built up there. Worth checking the intercooler too.

Thank you for your advice. It was a thin layer mostlyinside and coming from the two lower pipes, if these go to the inter cooler what stops the oil coming up I wonder. Inside the hiding was a very thin layer. Not running out but enough to for me to think " oh dear" lol. I read many moons ago about a green seal of some sort on the turbo that can fail and cause the oil problem. If not that where could I be coming from
