banzai510(hainz) Posted January 22, 2009 Report Share Posted January 22, 2009 you dont want to plug it!!!!! You either route to a PCV or open vent it or to a expansion can of some sort. Quote Link to comment
whitechef Posted January 23, 2009 Report Share Posted January 23, 2009 Don't plug it! You'll start blowing oil out of every concievable and inconcievable spot on your engine. I speak from expierience. Quote Link to comment
imtb Posted January 23, 2009 Author Report Share Posted January 23, 2009 Any sugs on how to vent it. Running dual carbs and no provisions on running to air cleaner. Anyway the $125 engine I picked up ended up having not one but two cracked cylinders. SOL. Quote Link to comment
banzai510(hainz) Posted January 23, 2009 Report Share Posted January 23, 2009 I open vent mine. Long as not to much blowby youll be OK. At idle more air blows out. As you rev up it will suck IN Thats why you dont want it plugged. Dual SU have a attachment for a PCV dual sidedfrafts dont and the guys with more monay use a catch can of soem sort.
