I will post back my results. I'm a bit nervous after checking out the Vanos Forum and reading some peoples issues after the install. HOPEFULLY everything will work out. My car runs fine right now and I sure would hate for something to screw up after installing these rings.

You should keep in mind that most posters on the vanos forum have a problem and are looking for help. This is a small percentage of people who perform the repair.

The common problem after the repair is an old almost failed crankcase vent valve fails. This valve and its 4 associate hoses usually last ~80-90k miles. If yours is older than this it might fail after the repair.

I've installed 15 Beisan kits. I had a problem with ONE car (my current ZHP). It had an exhaust solenoid crap out on me. $40 for a used replacement and the car purrs like a kitty again. This is top notch stuff and Rajaie has the best DIY ever made on his website.

Thanks, I'm feeling a lot better about it now. Its On.....

One of your excellent vids to go along with the install??

My CPS exhaust side was also leaking oil when i removed the connector..
I noticed the car feeling very weak.. Talked with Raj and i replaced the sensor with an OEM one and the car is fine.. Actually i changed both cps intake & exhaust.. I wanted to do it sometime as preventative maintenance, so i did it now..
Thanks again Raj!

Welcomed! Glad to be of help.

Rajaie, thank you for creating these seals to replace the crap that was put in from factory. Many many thanks.




Alrighty, it took about four hours taking my sweet time to do the seals. I know second time around it will be sub-three hours.

Here is what I notice already after 5 miles driving around my neighborhood.

- Quieter start-up (deepness in the exhaust went down a bit)
- Idle on first start was holding 1,000 rpm for thirty seconds then held a nice smooth idle at 700 rpm
- When braking, the rpm was staying low
- When in park, revving up a bit and letting go of the gas, the needle did not jump back up. It dropped quick, and slowly went to idle. Not a sharp drop with a bounce back off the 500 rpm mark
- On my way back home and the car being warmed up fully I gave it some decent amount of gas. The rpm went to 4000 rpm very quickly with zero lag, super smoothness and less resistance.
- The pistons with the old seals were floating around so much in the vanos unit. With the beisan systems they were in there firm with zero play


I HIGHLY suggest that you all do your seals if you have not. Shipping was extremely quick for an incredible product.

Few quick tips is to have a lot of towels ready, you will be basically have oil covered hands the entire time. Buy new vanos bolts, all gaskets, everything that was mention on the site for the job. The vanos unit will be packed with oil, so once you have it covered in a bag to put it down try to have maybe a cooking tray that's 2" deep to put the vanos in so all of the oil can get off.

does any one know the demension on 99 e46 vanos seal o rings, i have axis to viton orings all sizes and want to replace seals

Congrats on the repair and thanks for the very nice feedback and support!

Each vanos piston seal is a two ring apparatus. There is an outer Teflon ring that facilitates low friction reciprocation and an underneath O-ring that energizes the Teflon ring to cause a tight seal between the Teflon ring and cylinder wall. The seal rings reside in a small piston groove.
The seal O-ring is what fails, but it's not practical to remove and reuse the Teflon ring as it and the piston will get damaged in the process.
Viton O-rings are relatively inexpensive, but the Teflon ring has to be custom made and in this case uses a special high grade carbon filler.

See lui328i, there's no escape!

Or do you have a big pile of teflon O-rings lying around too?

Not sure if srs, but that would be awesome!

I plan on doing this once I hit 100k, so you have time

My friend wants me to do the seals on his car so at that point I will make a vid. I couldn't do it this time since I was doing it alone

Shoulda said something if you needed someone to hold the camera


BTW: done it before myself, so coulda added to the knowledge pool too.
Did rattle kit too.

Lmao, I'd rather make sure I did the job right the first time so the second time when I make the vid I don't screw up anyone.

Noticing the car pulling more into higher speeds without having to press down as much as before. RPM range moving more freely

Thats it! Enjoy!

I only drove like 100 miles, mostly highway and I notice the improvements. Is the city driving going to add even more improvements due to the lower rpm and torque range?

City driving will break in the seals better and you could get more improvements.
