sorry, I dont have chevy turbo pix...but the idea is the same, just on the other side. actually the pcv setup isnt bad at all...a turbo doesnt generate so much pressure that its all gonna blow when u boost...its a cheap and effective method..actually the radiator cap is a good idea too, i never thought of that before. PCV piping is what i would use too though, it handles heat quite well, and its not really gonna get all that hot anyways, but its tough stuff, I have a few things in my car that are made from pcv, and its mounted faily close to my exhaust, no problems and its been on for about 6 months now.
but heres the site for the last turbo pic...it has everything about it...so enjoy the read (I actually forgot about that link which is why i never posted it before)
