Vanos Seal replacement on 325i
On 30 December 2011 I decided to replace the Vanos sels on my ride. I had the seals as I bought them over the internet from Beisans Systems.
With the step by stem guide on my laptop, neatly placed in the engine compartment, I started with the replacement at about 17h00 the afternoon. My wife called be for dinner at about 19h00 and byby 21h00 I was finished with the entire job.
It was not as difficult as I thought it would be and must also compliment the procedures manual from Beisans, they did not leave out any details.
I decided to replace the seals because the car has 210 000 km on the clock and during the last couple of weeks it behaved stanged. First it would have a irregular idle speed on cold start up's in the morning and then sometimes it will loose power for no particular reason.
So far so good, I'm still running it cautiously and can therefor not comment on any significant power gains.
My advise to anyone attempting this Vanos kit replacement would be to take your time, dont rush it and work neat. It is not difficult to do, it only takes time.
