[QUOTE="AndrewMals, post: 450401, member: 21057"] Hi peeps I had this issue very recently The seal on my vacuum pump was also leaking This is the 2nd E90 N46 ive seen with this issue. The pump gives vacuum pressure to the brake servo. Under harder braking, i could smell a very distinct burnt oil smell, and on some occasions see smoke from the right side of the hood area. On inspection i found this [IMG]http://img.photobucket.com/albums/v232/johnono/DSC02810.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v232/johnono/DSC02809.jpg[/IMG] [IMG]http://img.photobucket.com/albums/v232/johnono/DSC02815.jpg[/IMG] so i changed the pump, and the newer Oring along side Also i change the chain tensioner and the valve cover gasket as it was also leaking a bit.. So far so good, :D [/QUOTE]
