Been lurking around the forums for a while now, and was wondering if I could get a few questions answered.
I currently own a 2000 323i -- 242000k (purchased at 192000).
I have put lots of work into the car and still love driving it, however through a bit of research on e46fanatics, I have noticed a common wear item on these engines (M52TU) is the seals in the double vanos system.
Currently the car runs great, despite what i feel to be slight hesitation when first jumping on the gas hard. If i roll into the throttle it doesn't appear to happen.
There have never been any codes or cold start issues, and the engine will rev happily to 6500 all day.
Realizing the seals are in fact certainly worn out, is it really worth the effort of replacing the seals with those from Beisan Systems if there is no real issues affecting driveability. As much as I would like to see more power out of the engine, I am rather skeptical that changing these seals will net any noticeable gains.
Any input is appreciated !
