the way they are in vacuum they will suck air from the crankcase, in boost they will stop boost from getting into the crankcase. ideally, i think the front one should vent to air so they is still somewhere for pressure to go when in boost. in boost this configuration could cause problems. if pressure builds in crankcase while in boost it has nowhere to go

 

really? so should i just undo the front hose or put the rear hose back into the intake manifold

 

i mean put an air filter on the 1st hose will it be ok for the catch can to be open

 

I would remove that T, leave your pvc side with crank vent through the catch can and into the manifold, that's fine, just eliminate the front breather from the equation. Take that front breather you removed and put a little filter on it right at the valve cover, venting open. Regardless of your current vtec issue, this config would be a safer bet for you, and who knows maybe it is related to your problem.

This way you are eliminating possible boost back into your crank with your CV and eliminating any oil to manifold during vacuum with your catch can. The front breather being open to atmosphere will remove any opportunity for more oil to get into your intake and also is an added measure to allow the engine to vent should your CV fail.

 

well if you want it done right... GO down to Autowave in Huntington beach, let them look at it and they will tell you whats wrong with it and how much it will cost to have it done right and running perfectly... best of all it will be done right the FIRST TIME if you take it to them.
