Rocker cover breather

[redline racer]

What is the real advantage of having a small pod style breather on the rocker cover????Is it worthwhile?

[badidas]

car might run a bit better no contamination from oil fumes mabey ?
apart from the bling value you will see nill gains

rice, but at least it gets rid of the pipe between intake manifold and rocker cover, dont want to go round a corner hard only to have oil get spat/sloshed into intake manifold

on 4a-ge's its better if u make an oil catch can off the breather, feeding back to the sump coz bluetops (maybe other engines as well..) have tandancy to build up oil in the head at high revs. but redtops have a drain. down the side.

catch can still having a breather on it ov corse for PCV.
Instead ov venting it back into intake, just disposing positive crancase pressure into atmoshphere.
venting it stops the oil "churning" i think.
