I'm getting an oily smell inside my 2010 Zetec 1.8HE. I usually notice it when I stop after a run although a few days ago I could smell it whilst running after slowing down for a built-up area. Popping the bonnet and taking off the engine cover I can't see anything obvious, nothing covered in oil, no split or disconnected pipework and the engine oil level is rock solid but the smell is definitely in the engine bay.
It seems to have become noticeable since its last service so I'm planning to take it back for the garage to have a look (I'm getting too creaky to drop the undertray and crawl underneath these days ) but I just wondered if anyone might have come across this before. I also wonder how the smell is getting into the cabin when the ventilation intake is at the base of the windscreen. The car's done just under 30K.
