My 530i is leaking oil, again! Had valve/rocker cover gasket replaced late last year, seemed OK for a while then leaking again. Then BMW dealer replaced the valve cover itself about 3 months ago as apparently it can sometimes get a small crack in it, cha ching! Had a new filter and oil done 2 weeks ago as part of other repairs for WOF (sob, sob). Now after noticing a bad smell the other day after a wee drive I see it's leaking oil again! Seems coming from up the top of the engine...suggestions?Cheers
