Administrators RTz Posted October 24, 2006 Administrators Share Posted October 24, 2006 The TB is cooled because blipping the throttle can overheat the throttle plate... You're all wrong... JohnC is right Quote Link to comment Share on other sites More sharing options...
JSM Posted October 26, 2006 Author Share Posted October 26, 2006 This is a Sunday driver. I'm only allowed 5000 miles per my insurance. It is a third car. So in my mind, grind it off! I'm curious how carbon builds when no gas is near the TB? Just air. Is this due to gases flowing back from the injectors? Doesn't make sense to me.

JSM Posted October 26, 2006 Author Share Posted October 26, 2006 Maybe I don't know what I'm talking about but if I vent the PCV valve why would it run through the intake? Quote Link to comment Share on other sites More sharing options...

Not following you. The PCV system pulls crank-case vapors into the intake manifold (with manifold vacuum) via the PCV valve. The PCV valve is plumbed into the bottom, central portion of a stock manifold. Quote Link to comment Share on other sites More sharing options...
phantaz Posted October 26, 2006 Share Posted October 26, 2006 related subject..... so if i finally get brave enough to try to attach my weber throtle body.. i dont need to figure out some way to reattache that weird pointy thing under the oem throttle body ?? which im assuming is the water valve. or did i wander into the twilight zone? =) i was always curious why there was water running to the Tb Quote Link to comment Share on other sites More sharing options...

naviathan Posted October 27, 2006 Share Posted October 27, 2006 Don't vent your PCV... I'll never understand why people do that. The PCV is drawing noxious and acidic gases out of the crankcase that can eat away at components and contaminate oil. It's actually a very good thing to have, not just an emissions piece as some think it is. Quote Link to comment Share on other sites More sharing options...

Your engine will thank you for it in the long run. The function of PCV helps in soo many ways, yet takes noting anyway in the way of performance. In fact, it can be argued that the PCV will help KEEP performance for the reasons listed above. Your bearings and rings will last longer, your oil will remain cleaner between oil changes etc. Keep it if you have the choice.
