So I have the dreaded/inevitable/harmless VTC rattle. After pulling the valve cover again today to make sure everything was in order, I still had what I thought to be a timing chain rattle. The tension/tensioner was fine, so I searched a little more to find the VTC issue. I was getting this intermittently, mostly on decel/shifting to neutral to coast/etc. for the past week or so. This evening I unplugged the VTC, and it was perfectly quiet, and I even noticed some more oil pressure (although this might have been because the car wasn’t fully warmed up). I stopped, plugged it back in…and the noise came back during driving, along with the lower oil pressure. I want the VTC performance, but am annoyed with the “diesel” sounds. I don’t want to replace the sprocket and solenoid, as it’s real expensive, and only a temp fix…i.e. it seems to happen again quickly. Hence the “diesel switch”… I can switch on the diesel noises and the performance when I need it, then switch it off for daily driving. I haven’t came across any real fix for this, besides replacing everything (~$800USD at least). Has anyone found a fix that I haven’t found? If not, I’m going for the switch…lol ---

Sweet…I’ll be in contact before the winter. I’ll be tackling a re-build…
