Today I finally received a reply from them.

Here is the response I received from the shop foreman:

"My factory rep suggested that I should ask via TC case, which I did, their response was "It could be the non-return valve". I asked if the non-return valve is the same as the one in my attachment, he could not confirm it but said that it is worth a try so when ever you're ready, let's give it a try."

So it looks like I will be bringing it in for this "check valve". Very anxious to see if this fixes the problem. Other than that pesky noise, the car is still a dream in every way.

I will keep everyone updated and will be doing another oil analysis soon.

Thanks

Mike, this is with regard to the cold start "grind"?
