Well, I know there is a piston, oring.. spring and solenoid. Haven't noticed a check valve but if you are looking just to replace the solenoids the dyi are here. you just unscrew them. very simple .. just like a spark plug..

I didn't want to say anything because the OP mentioned they looked in the bestlinks, which is the only place I looked.

Therefore, the OP already knows of the Besian DIY (pictured below).

So, what I need to ask then is what's exactly is it you find MISSING in the check-valve removal procedure in the Besian DIY?

Here is just one tiny snippet of that well-known DIY...

I said I searched, did not find it and no you are not hurting my feelings posting info, I did not look at the vanos procedure obviously or I would have seen they mention the check valves

I did find an X5 howto on another forum that has step by step that I needed, no where near as involved as removing a vanos for seals

Clever, Clever BB... Hey, isn't your usual pattern to say something on the order of ... I typed /x and then F3 and found?.... I do have one more question, I'm curious, how do you quantify 'well known'? It's not too often that I've seen a thread ask this question in fact I can't recall when was the last time this questions was asked. Thanks in advance..

That explains my confusion because vanos and besian are almost synonymous on this forum, so, I figured you had to have already looked at it.

BTW, I've never done my VAnOS, and I only skimmed the Besian (because I knew if it was important, it would be there), so pardon my dumb question.

But, is it as simple as you screw in a threaded rod, and then you just pull the thing out with backward force?

Would you kindly provide a reference so that I can make this thread here (i.e., your thread) the canonical thread in the bestlinks on how to remove the VANOS solenoid check valve?
- How to remove the VANOS solenoid check valve (x)
(Where x will be this thread.)

That way the next person with the same question stands on your shoulders.

I don't see anything clever in what I wrote.
A question was asked, and all I did was look up the question.
Since I found that answer in the same spot anyone would look, I had wondered if the procedure was missing a step or three (it happens).

Nothing clever whatsoever.

Let me tell you my M.O. for most threads:
a) I skim them (if it takes me more than about five seconds to skim the entire thread, that's too long).
b) I decide what the basic question is talking about
c) I type the keywords and provide the link
d) I move on to the next thread.

Since I skim threads, I can easily get the specific question wrong; but, I generally have the general topic figured out in those few seconds.

In most cases (99% of the time lately), the answer to the question has been well documented (as it appears to have been in this case), so, my MO should work if the person clicks on the links.

In this specific case, I had known (from the way the OP was written) that the OP had already said they had clicked on the links, so, I clicked on them myself, to see why they hadn't answered their question.

When I saw the answer as plain as day, I questioned my assessment of the problem set (which sometimes I get wrong).

I think you skimmed my answer!
I never said, nor even implied, that the specific question of how to remove the VANOS oil pressure check valve was a well known question.

What I said was that the Besian DIY is pretty much the universal standard for VANOS, so, I knew that anything worth asking about for VANOS removal procedures would be in that DIY.

Again, when the OP intimated that it was not in that DIY (by implying he had checked all the links in the bestlinks that referred to VANOS), I simply LOOKED at the DIY (took me another ten seconds).

When I saw it, I was perplexed, so I asked the OP what was missing from the procedure (since I was sure the OP had seen it since it's the procedure EVERYONE goes to).

Anyway, the answer is simpler than I had thought.

To move forward, I ask the OP to snap a picture or two of the procedure, and we'll make THIS THREAD the canonical thread, so that when someone types in /check valve f3, they'll find this thread in the future.

I would not call this well known as I searched a lot on rattles and find a thousand links to the cam chain tensioner but not this check valve & vanos rattle, I Found the x5 and some landrover info before posting here figuring there was probably an e39 howto somewhere but I have not found one yet, the besian instructions are very different and for a full vanos rebuild, I'm definitely not doing that as my vanos works fine. I have done vanos seals before and will never do one again unless it absolutely requires it.

looks pretty easy

We're still misunderstanding each other, but, let's drop that discussion, as it's not important what we thought.
What's important is HOW to do the job.

Moving forward, thank you very much for that explicit reference:

M62 Vanos Seals and check valves
My X5 started to get a slow leak of oil from each of the Vanos seals. So I replaced the seals and also changed the check valves that are behind the solenoids.

I didn't use the BMW special tool that was mentioned in the Bentley manual. I used some plumbers wrenches that fit the solenoid. I also used a bolt to thread into the check valve and pull it out.

The passengers side was easy. The drivers side involved draining the coolant and removing the water pump - radiator hose assembly.
Took 3 hours taking my time and cleaning things as I went.
What matters is that this thread is now a canonical thread in the bestlinks, so that someone who searches /keyword should find it.
I always try to put keywords into the reference that others would use (even purposefully mis-spelling them, if that's what people use), but I'm not sure what keywords they'd use for this DIY.
And I noticed that the part is listed on the tag in the picture below as a "non-return valve", so, given these keywords ...

How does this proposed bestlinks reference look so that you would have found it, had it existed?
- How to remove the vanos oil pressure solenoid check valve non-return valve (1)


BTW, I wasn't sure exactly what BOLT SIZE to use (thread + pitch + width).
Do you have that bolt size so that the next person starts with the correct size.

Thanks for confirming the bolt size, as this canonical thread will help others gather the right tools ahead of time, so it's good that you tell us whatever you can while it's in front of you.

BTW, while it's fresh on your mind, what is the size of the check-valve o-rings?

Note: We would want to add the o-ring size you report to this thread so that others can order it, in advance, during routine parts ordering:

Generally what is needed is the ID and OD, or the OD and the cross section, usually in millimeters.

I usually measure mine with a mic, but even a caliper would work.
