The check valve is simply a flapper. They aren't restrictive and the one I used was fine for oil. I didn't trust an oil filter for back flow protection. Not all filters have a back flow valve so make sure you get the right filter.

I had great success with my accumulator. Just make sure your oil pan is your first line of defense. An accumulator is simply the back up plan.
