But if she gets back to working well without your cyber-cap

I'd definatly put a reg cap back on.

Or a slate cap mounted on bricks.

Well I was taking the advice of removing the cap. I got up on the roof and just stared at this thing until it hit me.

If you notice from the picture, the cylinder is a solid sleeve before the holes start. I finally noticed that the liner coming through the top plate was a couple of inches below where the holes start.

I removed the solid section of the tube so the chimney liner was "in the open" and WA-LA everything is back to normal, 30 degrees outside...75 in the house, just the way I like it.

Thank you very much to everyone who had advice, if it wasn't recommended to remove the cap completely I may have never noticed my fabricating error.

So you freed up the chimney liner? And that worked? Hmmm. Interesting. Well as long at it is working for you, that is all that matters.

Enjoy your nice warm house.

Not sure what you mean by "freed" the liner. It still feeds through a top plate to keep the liner centered and rain/stuff from going down the chimney around it.

But, Taking away the solid sleeve to allow the top of the liner to be in "open air" is what made it start working properly.

The only thing I can come up with is that portion that was unperforated metal would be colder than the terracotta and was acting to cool the gasses which would slow down draft.
