the pcv is like dave said to stop the crankcase brething to atmosphere it has to go throught the engine first when this is done on a ci engine there is a risk of the engine running from the fumes that comes out of the crank case and when this happens there is no way of shutting the engine oof it is freaky to see and the engine does not come out of it alive the engine will run until it blows up or runs out of tasty fumes and sods law dictates it is the first one
i think it is to do with emissions that it is fitted modern cars everything goes through the engine if it brethes they stuff it in the engine intake
well excuse the usless information
im going to shut up now and return to my corner (HERE HERE)
