Hi, I have a zetec 2.0 auto, the car has had a rocker cover gasket replaced as it was weeping a bit. Problem is when I open the bonnet I can see a misty oil smoke and a smell of burning oil, I cant seem to find exactly where its coming from but it looks like its behind the downpipe of the front exhaust, its a staright car with 67000 on the clock, are there any common probs to look for?

Thanks

Matt
