I replaced my valve covers. And engine doesn't throw any codes anymore but to check if one was stored. I waited for it to have a moment to pause and slower blinking. The blinking was steadily same pace and had no pauses. Not sure what this means

 

As I am understanding this, you are getting all 1's. That is a good thing. All 1's means that the computer is not finding any faults.

Not sure what your prior issues were but the computer doesn't catch everything but as of now you are good to go with all 1's.
