I suspect that the O rings are just fine from that ebay seller and I may purchase them myself to save a few bucks and put the competitive fear into $60.00 sellers.
You can make Viton any color you want to. Most of the ones I've seen have been green.

Green O rings are HNBR which is not Viton....there are industry standards. However, facking China will make them what over the fuk color you want.

Don't worry about whether the o-rings are "real" Viton or not. Viton o-rings, when purchased in quantity, are way less than a buck a piece. I don't think anyone would bother with "fake" Viton rings to save a few pennys. The expensive and critical part are the Teflon seals. I don't think these are "off the shelf" items and the dimensions are critical.

Even though the failure item in the system is the Buna o-rings due to compression set, you need to destroy the Teflon seals to remove them, and unfortunately they are the expensive pieces in the kit. The question would be whether you trust the supplier on the quality and dimensions of their Telfon seals.

Choice A: Known quality, reliable customer support, member of the BMW community.

Choice B: Unknown quality, cheaper, probably comes from Shenzhen China.


Take your pick.

IDK current prices on beisan (sp?), but I'll echo a few comments made already.

Raj discovered, designed, sourced both the problem and the solution. His diy instructions have saved us all about a $1200 repair at a dealer for $50.

I personally wouldn't trust an ebay seller with 850 100% reviews. They bought something and installed it...seems fine. 100% rating. But, where is the engine in 100K miles?

You're doing a bit of work to get to seals, but once you've done vcg, it's just another 30 mins top to install seals.

I'd wonder if these were knock offs. But, if they can be traced back to Raj, then I'd trust them.

And I would get a new valve cover...that's a 100K mile repair...and I wouldn't want to waste my time cleaning rtv off the head, only to have a failed seal...not for $20 or whatever vcg costs.

I like this. And I've already gotten a new valve cover. Dealer installed. 10k ago

If you simply want Viton O-Rings, there are plenty of sites that will sell you single O-Rings, listed by the industry standard size numbers. In fact, I believe you can even get them on Amazon. It would come out to be less than $15, most likely.
But, I will say again, I do not believe that the O-Rings offered by Bessian are off-the-shelf items. I had the same thought at one point, until I read the background on the Bessian solution, and I saw that what they sell is a specially produced O-ring, with an interior portion made of some material that would prevent the permenant compression of the O-ring, with another material molded around it. I really just don't feel like searching for it. If you really want to know, that info is out there.
There are times you can beat the system, and bypass the normal supplier, but this is not one of those situations. But, there is always someone who thinks they can, ans someone else is usually there to help support that belief, and make money doing so. They tend to be on eBay, strangely enough.

It's outer Teflon seal that's non-standard, and where I imagine most of the cost is. He plainly states as much on the intro to the double vanos repair procedure.

Just my two cents...

Those seals at www.bmwseals.com are just as good or better than any other seals. I purchased some and had them inspected and they are Viton and the outer ring is Teflon/Graphite combination, which is stronger than original Teflon.

Just for those who were wondering. I also emailed them and those seals are made in the USA. They respond pretty quickly via email too. Personally I would not always go with the lower price for something, but for these seals I would. Just look at this person's Ebay feedback, and then read the reviews on the seals, 100%, which is rather impressive. They ship with tracking. I like the fact that it's made in the USA myself.

Beisan might have started this, but things have evolved. Everyone should just do their own homework and pick the solution they are happy with.
