PCV Delete?
#6
You're all suggesting that he create a vacuum leak? That's a bad idea.
If he doesn't block off the PCV valve (to-intake manifold), then he might as well leave the tube off the throttle body too, because that is creating a vacuum leak. The breather would allow UNmetered air to enter the crankcase, which would then get sucked back into the intake manifold via the PCV valve. The computer will not be adding fuel to account for this secondary (unmetered) air source.
If you absolutely must run a breather, disable the entire PCV system. That would include blocking off the 'inlet' hose from the throttle body to the passenger valvecover, as well as the PCV valve/hoses on the driver's side intake manifold. The exact procedure will vary depending on year (1992-1994 is different from 1995-1997).

Keep the PCV.

Yea, definately keep the PCV. The one on the Valve Cover is just a secondary vent. I got a little stainless steel Vent Filter from Autozone, and put it on mine. Then I plugged the hole in the Throttle Body. Look at my Cardomain link to see it if you have any problems with it. The benefits of this that I can see is that hot air and Oil is now venting out, instead of going in that tube and into the incoming air, which will reduce power.
