After noticing white smoke w/a bluish tint coming from the tale pipe of my 745I , I began to read blogs on consumers experiencing very similar issues. After reading over a dozen blogs that described the exact same issues I experienced, it became clear that the issue was the VALVE STEM SEALS. They needed to be replaced. My check engine light was on and read code p0492 (secondary air Fault bank 2). I had the emission control valve replaced a few months ago & in less than a week, the check engine light was back on. At this point, I felt I knew more than what the auto repair guys did & besides, my pockets couldn’t handle seeing much more of them, so I decided to do the work myself, of course, this wouldn’t be my first time. I purchased both the AGA Valve Stem Seal tool and AGA Secondary Air Cleaner Kit to complete these tasks. I will do my best to explain in detail all necessary steps needed in order to eliminate the above listed code and clear up the white smoke blowing out of the exhaust pipe. TO COMPLETE WHAT I’M ABOUT TO SHOW YOU WILL COST TWO ARMS, YOUR FIRST AND LAST BORN AND YOU’RE LEGS.

Difficulty level 1-10: 9 — because of so much that have to be removed and the sensitive sensors that could be broken while removing and installing. It took me five days due to getting used to the tools that I had to use.
While everything is a loose its time to replace the Valve Stem Seals using the N62 Valve Stem Seal Tool. I’m not going to go into detail about how to use the tool because AGA does a step-by-step video of the entire procedure. Note: When doing the valve stem seals make sure that intermediate lever is in place with the spring behind the V.
I would say after a few times of using the listed tools, the job became a lot smoother.
As for the code p0492 (secondary air injection) while everything is a part, it is easier to slide your hand behind the engine (so you don’t need a pair of little girl hands) to remove the air tube for the cleaning that specified in AGA video. It just makes the job go a little easier. I’m not going into detail about how to use the tool because AGA does a step-by-step video of the entire procedure
