Has anyone here replaced their VANOS seals?
Today I ordered the seals from: beisansystems.com

How long did it take to get them? The site says 1-2 weeks :(

ya it took about 1-2 weeks. noticeable improvement on cold starts. Seems to have more low end power as well - it was too scared to test it out more as my subframe ripped out. I will know once I get my car back from the dealer.

i did mine in abt 5-6 hrs with a friend. i have a stick, thus, the electric fan in the rad, so i saved some time and frustration there... the replacement is pretty straight fwd, just start early in the day just in case something goes wrong. i replaced everything they suggested. it looks a lot more intimidating from the website walkthrough than it really is. if you have done car work in the past, you should be fine...

i noticed an improvement in acceleration, it seemed more linear. the problem i was looking for fix still persists tho...

the problem i was looking for fix still persists tho... That sucks, but I guess the seals were shot anyway...

The only reason I am changing mine is that the car seems to low on power below 3000 RPM, after that it starts to charge. Also, I want to have a look under the valve cover to see if there is any sludge.

ya, they were quite a bit harder than the new ones. and the power gain was noticeable... worth the time to do it yourself..

When would you typically change these out, and does this apply to all E46's? e.g How does this impact my 2003 325iTA with 80K (M54 engine)?

He believes any car with 20,000 miles has hardened seals.

I am guessing the power gain was in the lower (<2500) RPM range?

Hey.. Does a 323ci have dual Vanos... If not, can it be installed...
also how much would it be around to have two exhaust pipes leading to the muffler instead of being tied together mid way???

Yes, 323ci has double VANOS. I'm guessing you could just flat out replace the cats and muffler with one from a 330. At least that's the way it was with E36s.
