141K and no issues here. I run AT-205 in my oil changes. I only have vehicle history from 109k.

No smoke. No replacement.

Note: did smoke badly, but it was the CCV system malfunctioning. No smoke since repair.

Trust me I've tried every single cheap fix I found. After a long denial, I come to accept it's my VSS lol

Oh, ouch... but since you're doing the valve stem seals, what else are you going to do?

My x5 is at 172k miles. Still no issues.

My new to me e60 on the other hand.. only 55k miles and noticed white smoke after extended idle. Gearing up to replace the vss on that rig

2005 4.4i with 116500 miles on the clock, VSS done at aprox 115000 +\-. Sucker smoked like a freight train after extended idle, 10 \ 15 minutes, and sent up pretty consistent smoke signals even from a few minutes of idling at a traffic light.


Got tired of being "that guy" real quick and did VSS, 1500 miles later and no smoke, I can let it idle all day and no smoke - it's such a beautiful thing!


And yes, my old ones were so hard and brittle that they chipped if I dropped them on my garage floor! Terrible design...


If you do this job make sure you order (and receive) the revised VSS! This is important because the new design removes the "pocket" where oil would build up and adds an additional "sealing" ridge.


I stress this because I specifically ordered the new design, confirmed with the Supplier that they were in fact the new design and then received new OLD stock (old design VSS) that had been on a shelf in some warehouse for who knows how long...

^ Did you do them yourself? Where did you order parts from?

I think ~107K on mine. 2004. No seal replacement.

Update:

I went ahead and did the seals later in 2017 when I was doing other gaskets. That would have been after the NorthEast summer road trip that year which was about 5k miles. I could look it up, but I would guess that I had about 115k when I elected to do the seals before there was a problem.

I'm at 136k now. No problems. These things love to be maintained. :thumbup:

Yes, I did mine myself and ordered everything from FCPEuro. I really like their lifetime warranty on everything - not that Iíll ever be doing this job again [emoji50]
