I had an ideal on a Oil Catch Can between the PCV Valve and the intake. I have not seen anyone recommend this and was wondering if a Oil Filter Relocation Mount would work well. Would it be too restrictive? I was thinking that the oil filter would work as a good baffled can. I know they are meant to let oil through but no more oil than goes through the PCV system I thought this might work good. It should how a vacuum and it would look like something that is suppose to be there. Route the hoses from PCV to Inlet and Outlet to Intake.

 

I have a Kobalt Water/Air Separator meant for air tools as a catch can and it works great. The tank holds about 70cc and only needs to be emptied about every oil change... theres a DIY tutorial on 6thgenaccord.com and it costs less than $20 to build.

 

I have a Air tool Separator on it now and it catches a little oil but still lets a good bit of oil through.

 

Hmm... does it have the nipple on the bottom to drain the water?

 

Minor amounts of oil vapor pulled in thru the intake are used to enrichen the fuel air mixture.
It was considered by the engine design/ECU control.

Depending on the year.....stopping the oil vapor flow completelymay have adverse effects on fuel consumption.

On the other hand, if oil is dripping out of the intake, that means excessive blowby from collapsed oil wiper rings, or other problems.
