QUESTION: Bluish and very thick. Fills the whole place.

Answer
Hello -

Perhaps you have a serious oil leak into the cylinders. Blue smoke means oil is burning. Remove the spark plugs and let me know if it is fouled. Also while you are at it take a compression test of all the cylinders.
Let me know the result
