Not a very technical post here but I took off my dual solenoid and cleaned it out real good. I was pretty fascinated with it so I snapped some pics. And what the hell I thought I'd post them up.
This is the VTEC solenoid from the 3 Stage VTEC engine which came out in 1996 in Japan and several other countries in the Civic VTi. In Japan it's stamped "D15B" and in other countries it's stamped "D15Z7". Stage 1 is 12 valve mode like the VX (D15Z1) and HX (D16Y5). Stage 2 it switches to 16 valve operation. And then Stage 3 is your standard SOHC VTEC.
