I have a few of those engines and don't remember seeing the pin holes in the lines I will look again tomorrow.

Yes I sprayed with soapy water once I heard it whistle to see where it came from. Between the QuickServe info saying it’s ok to have some soot there, and rawze advice about the holes being for keeping moisture out, I think that this is normal and I just hadn’t heard it before. I will be keeping an eye on it though.
