Hello and thank you for having this forum. As know know the m56 valve cover is a nice upgrade to the m54. Finding the valve cover used all the time is easy here is California. But, how can we replace the ccv prior to the conversion? The problem seems to be finding the right cap. And your video clearly shows you've recieved two of the right caps with your purchase. This means, it is possible to find this darn piece we are all looking for.
There are other forums which, because we can't find the ca, now are trying to test their 3d printed versions, but are failing because they are home made. This is how desperate we are becoming. This is happening currently as of this post.
In your m56 valve cover video, which I've scoured over many times to find how you got yours, you mentioned that it came with two caps, and that you think it might be from the n10 or n12 mini cooper valve cover.
Pleased help us find the exact right cap so we may save or little cars from unnecessary mechanical drama.
Any definitive solution, or suggestions that may help us find this m56 valve cover cap would be wonderful.
