I think that is true. I saw a brick chimney that was stained brown on the OUTSIDE from creasote. The creasote migrated through the clay liner, bricks, and mortar. He had to get some type of acid wash I think to clean it up. (as best as it could be)

I am going to go the chimney block route, but instead of clay liner I am going to put a steel liner this way I don't have to worry about it if I want to burn wood. I looked around and I did find this product called Brick Block. It is chimney block designed and stained to look exactly like brick. They are around $15 each depending on size.
Chimney block is an economical way to go but one caveat. I have seen these blocks deteriorate over time. Someone told me this is because they were painted. After hearing this I started to notice this appeared to be true. All of the deteriorated chimneys had been painted so the anecdotal evidence suggests there is something to this. If the color of masonry block does not appeal to you maybe try the Brick Block. Just my 2 1/2 cents worth...
