Im going to try and get some more pictures about the things Im talking about. Particularly blow of valves, as some of the things I talked about in their operation is difficult to understand If you dont know how a BOV is put together. Only problem is I cant seem to find any pictures of disassembled BOV's online. If anyone has a spare one laying around, and could take some pictures of the piston and cylinder assembly, it would be awsome if you could let me know. Thanks!
