Re: what to do with metal tube from VC to intake
I had a breather filter on my old sohc turbo for years. no problems. and with the other tube, that's a coolant line. so you either remove the entire thing (valvecover to intake and coolant line) or you have to cut them apart. makes more sense to remove it all as one, and replace with necessary hoses. that's what I have done on my EM1

Breather =Bad
The honda crankcase breather is a POSITIVE pressure ventilation system.The air from the intake blows into the valve cover. It is NOT a negative pressure ventilation system...it does NOT suck air from the valvecover to the intake.
Breathers remove the source of positive ventilation that repressurizes the POSTIVE CRANKCASE VENTILATION (PCV) valve.
There is less pressure in the crank when you add a breather at the valve cover. The consequence of this is you get more positive blow-by from the combustion chamber past the piston rings and into the crankcase. More blow-by means less cylinder pressure...less cylinder pressure means the burn is slower and less complete...the result is more emissions and less power. **Taken from Prelude online.com**
