Yes, I'm running a catch can, The M7 can plumbed according to M7's recommendations (and I'm aware of M7's reputation).
Out of curiosity, I checked the cap on my wife's 4runner today. It's a completely different car and engine (V6) but driven and stored in basically the same conditions. Her car also has a bit of sludge on the oil cap. So I think between that and the negative block tester test, it's most likely condensation. For now I think I'll just keep an eye on it, and reevaluate once the temps warm up (since I can't plan on the humidity dropping, this is Maryland after all....)

This is the correct way to install it.....

Great illustration! Im on the verge of pulling the head on a friends R53 due to coolant in the oil. No oil present in the cooling system. Illustration makes sense.
