Can i guy get rid of this line out of the air box, and why is it there is it just for emissions i dont understand why they would run burnt exhaust gasses back to the air box other than for emissions, it just seams like it Wastes the avalible space for oxygen
There not running burnt gases into your airbox. It's there as a vent for your crankcase. It can be taken out of airbox but you still need it filtered. You do not want water or dirt to get into that hose. Is just leave it alone, it in the best spot already.
So now that i changed to velocity airfilter its not getting filtered air, if its not positive air line then why does it seam to be pushing black oily. Air into airbox im not home right now to see if it is sucking or blowing ???im confused
As the piston moves up and down it moves air in and out of the case where the crankshaft rotates just like the piston moves air in/out of jug. The blowby tube just let's the pressure/vacuum excape. The oily residue is just a mist of engine oil.
I would have to put something over it just for peace of mind. They have small filters that may work at some auto stores. Or maybe extend it and point it downward so it has a harder time getting dust in it.
During a dusty trip i think i sucked up dirt thru this vent. now need new pistons, crank and valve seals. this opening needs a filter. Running a no-toil filter and ther is too much space to get dirt in this vent.
