on top of the engine theres a little nipple thats not covered but it shoots air out of it just wondering if its suppose to be covered so no air gets out or if theres a hose thats suppose to be on it????? any feedback wold help

 

i think you are refering to the crank case vent. and if so you just need to put a filter on it so no debree goes into your engine.

do you mean the nipple that the black hose is coming off in the photo?
if so its the crank case vent.

 

yup exactly so what do i put a hose or a straight filter?

 

i run a hose up to a filter so it doesn't get dirty
