PontiacFan,
The reason why I haven't updated the oil fill hole pics is because there have been no improvements in that area. However, judging by what has collected inside the oil filter housing(post #1593338 on page 1) and on the CVVT gasket mesh screen(picture above your post), rx does seem to clean albeit slowly. That being said, my rx experiment has run its course. Would I continue purchasing more quantities of rx for maintenance doses? Probably not. Do I think the product was beneficial to my engines? I'd say yes.
I encourage others to draw their own conclusions and make their own decisions.
