I have been planning on running a breather and no pcv for my turbo build. Then I remembered a buddy who had done this and ran into a little water in his oil. Do you guys running breathers have to change the oil like every 500 miles or does it stay pretty clean? I can deal with the smell of breathers, but I dont want to have to a large amount of contaminants in my oil. I've read enough pcv threads to make me sick.

 

i have an upgraded check valve for my pcv. throttle body is capped and a breather on the passenger valve cover..

i haven't done an oil changed since i've been boosted.. (dec.) i should probably do that soon, maybe this weekend

 

Yea your oil will get dirty faster but I've never had an issue with water in my oil. I probably go about 4k miles between changes with mobil red cap. Just depends on how hard I've been driving it.

 

Just run the stock PCV system (with a catch can and check valve inline) and a breather on the passenger side valve cover. Unless you're using the MAF in which case it gets a little more difficult as all ingested air should be passing through the MAF first, otherwise it's a glorified vacuum leak. This is what my tuner told me.

 

Thanks for the responses everyone. I think I'm going to just run a breather until I can get a pcv setup I'm happy with.

 

I just run a breather...oil looks fine. Yes there will be a small amount of water in the oil, however this will quickly evaporate once the oil gets up to temp.
