I don't think there is a way to tell which valve cover you have unless you pull it off and look at the underside of the casting.
If I recall from a previous thread, you may have posted that your engine is not using any oil at all between changes (I could have that completely wrong and thinking about somebody else). If that is the case, the urgency on any of this stuff definitely gets into the "preventive" mode, versus "fixing" mode.
My belief now is a catch can is a great device for insight into what is going on inside. On an engine that uses oil, it will tell you if you are pumping it out the PCV and back into the intake, which in measurable quantities is not good for anything. If you see large quantities, you know you need to at least get that valve cover pulled and check to see what part number you have.
Yes, that was me...probably driven under 1000 since purchasing at 87k (have to check bill of sale to get exact) and seems to not be losing any.
I'm beginning to wonder if original owner did have it done... if the guy wasn't hurting for money and went in for an oil change and was losing oil on his relatively new engine and they had the service bulletin, it's very possible that he just did it. But see, with the way my mind works I NEED to know lol
