I noticed smoke coming from under the bonnet on the NS so i stopped to have a look and noticed smoke piling out of this It looks like its bolted to the top of the turbo, anyway i took it off cleaned it up and put it back on about two weeks ago. This morning i noticed the smoke again and on inspection found the pipe that goes into it has gone brittle and developed a 1 inch crack. I think it might be time to do the PCV system but on the guides on this forum this part does'nt seem to appear anywhere. The pipe that has cracked leads to the charcoal emmissions filter thing under the NSF headlight. Will i need to change that aswell. Any help is much appreciated.
