I'm considering blocking off my head vents and running a -10 or -12 breather solely from the oil filler/breather to a Morosso breather tank (or the like). The idea here is to keep the crankcase at a lower pressure than the heads so the oil tends to move from high pressure to low (aka from the heads to the case).
Anyone else doing this yet? If so any comments or pictures? Thanks! |

It has been my experience that flat motors seem to have much more oil in their internal air due to the proximity of their crankcase vents to all the whirily bits. Also remember the cam/lifter going in & out in close proximity the the heads oil drain tubes from the heads of a T-4.....that cannot promote good drainage.
I remember an old pic of some plexi-glass valve cover showing the valve covers 2/3rds full of oil at higher revs. Personally, I don't give a shit how, but you need to deal with that oil loaded windage. Chances are there will be an honest difference of opinion on that and anyone that disagrees with YOU is an asshat. (IMG:style_emoticons/default/biggrin.gif) |
