[Spits] GT6 Running Warm revisited

[joe at ados.net]

The one thing to consider in this is that if you didn't make any other changes/adjustments, the car 
may now be running lean as the PVC system will add some air (from blowby) into the intake tract 
after the carburetors.  You may need to richen the mixture a bit to compensate.

 I don't know for sure.  But, gut instinct, I doubt this makes any
significant contribution to cooling.  Sounds more like a DPO bodge to get
rid of the PCV valve, no more.  For any effective air cooling there would
need to be a continuous stream of cool air entering the valve cover, which
would then require a separate outlet for the warmed air to come out again.
With this vent pipe, the only flow along it will be a (hopefully slow)
passage of blowby gases coming out of the valve cover.
