sorry to burst your bubble but it probably will not pass emissions. i beleive if you live outside of phoenix area you only have to pass saftey inspection.

i understand that u dont run a PCV as i do not either. But u have nothing pulling the gases from your valve covers... You need to connect the two braided hoses comin off the valve covers to a T and then to one port on the oil catch can. Then use the second port on the catch can to go to the intake which will create a negative pressure in the catch can. Thereby pullin the gases out of the valve cover...

right now what u have is bad... there is no escape for those gases

OP your system is fine as long as the catch can has a breather filter on it to allow the can to breathe.
