If it still runs and isn't running away then it's not too much blowby!
Is the engine cold or running at operating temp? If it's cold then try it again when it's warm. Also how long ago was the valve adjustment? If it was just was the day you took the video, try it again after you run the car for a couple days. The valves may reseat a little and reduce the blow by.
Other than a rebuild, unfortunately not much can be done about blowby. One thing you can try is pouring a little bit of Marvel Mystery Oil or brake fluid into the cylinders and let it sit for a while. This will break any gummed up piston rings. You'll have to remove the injectors to do this. Change the oil post soak, to remove any fluid that drained down.
You can use thicker oil to help reduce the oil loss to blowby, I've also seen people put filters in the bypass hose to filter out the oil so they don't burn it.
