Hi and thanks for using 2CarPros. Com.
That much blow-by is not normal and indicates the compression rings are not doing their job. Now, that can be due to excessive cylinder wear, which should have been checked prior to replacing the rings, the rings were installed incorrectly, or simply because the cylinders were not (at least) honed. When the engine was new, the manufacturer honed the cylinders. Basically, tiny high and low spots are created in the cylinder. It is important because it helps the cylinder wall retain oil. Without it, the rings and cylinder walls will wear faster.
Now, from normal usage, a glaze is created on the cylinder. Basically, that is caused by the piston's movement within the cylinder, flattening the original imperfections created by honing prior to assembly. Without removing the glaze (by honing), the rings will not properly seat and will wear much faster.
So, with that being said, if the cylinders were not at least honed, the process was most likely not successful. It may have seemed a bit better at first since more compression was created, but that will go away fast.
I hope this is helpful. There is more to it than just honing the cylinders, however, that is a minimum requirement when replacing rings.
Let me know if you have other questions. And yes, the blow by is caused by bad compression rings (or worn cylinders which should have been checked prior to replacing rings) and the oil consumption and smell is because the oil rings are most likely worn or the cylinder was too big to start allowing oil to bypass and get burned in the combustion chamber.
Feel free to ask questions.
