Was giving the engine bay a bit of a clean today when I noticed a little oil on the block under the intercool/Turbo checked the oil level its fine the car also runs fine, one of my mates had a look and said its probs just coming out the engine vent hole/hose and said I shouldn't be worried about it what's your thoughts

 

If the breather tubes are a little loose there can be some residue left on the block from time to time.

Just keep an eye on your level..

 

That sounds about right I think, residue is about the best way to explain it thanks
