Mr_Reverse By the screens, do you mean the ones inside the vct soenoid itself? If so, yes. I actually checked it again the other day, pretty clean. I'm only having a problem with bank 2, at least, that's the only dtc. I replaced all the o-rings as well that had to do with the vct operation as well as any other ones. This whole thing is weird. It has a constant rattle now from that bank now not just at cruising speed. Also, that p0021 seems to be intermittent.
