Crank case breathers

Ok theres those 2 crank case breathers one connected to the intake one to the turbo. i know the one to the intake when you buy an aftermarket intake you reconnect that. now me question is my new turbo doesnt have a spot to connect the one that was connected to the intake on the turbo side. What should i do with this one just connect a breather to it or what?

You need to connect that back into the intake, get a barb fitting, drill a hole in the intake and attach it.

You have to take that end piece off of the steel braided hose, use some picks to do that, then you can attach the hose to a barb fitting. It wont seal properly but if wrap some electrical tape around the barb fitting it'll be a snug fit.

The one that had the plastic piece that connected to the intake can just be plugged. The other one I cut off and ran a piece of hose to the intake tube.

You disconnected your PCV? Surely not.

or are you saying you relocated it?

The pcv valve is in the intake mani itself. The one with the plastic piece is just a breather. There is nothing on the inside of the valve cover but an empty hole.

The car has been running perfect since and I haven't had any noticeable oil splattered all over the engine compartment either with the crankcase air breather.
So you still have the one that connects to the intake then and the one that connects to the turbo you took off?

The one that connects to the intake has the PCV valve on there, you need it.

In my case I'm running a 3" intake with a barbed fitting, I ran fuel line hose and put the PCV valve inline just like the factory steel braided was fromt he intake to the valve cover stock location.

But yes, you need the PCV valve., whether you hook it up like I did or leave it ran with the factory steel braided line.

This is just something I found quick. The tube that went from the intake tube to the valve cover is an air inlet, so is the other tube from the turbo to the valve cover. So it still pulls all the air it needs though the other tube.

"yes, the PCV vacuum side is a port in the cylinder head that is covered by the intake manifold. The hose from the intake tube to the camshaft cover is the air inlet.."

Listen to how hhr says to do it. I don't want to be liable lol. Also don't want to clutter your thread anymore. I know how I have it is how the ZZP big turbo kits are set up.

Try it out and tell us.

Put a barb in the intake track down by the turbo inlet, hook a vaccuum line to it and tell us if the line sucks or is pressurized by the intake air.

The you will know whether hooking up the breather line to the intake will work.

I run a crankcase breather no problems, along with a few other guys with turbo upgrades on here but would be interested in the results.

Suck or blow

I don't know man, since cmiller didn't tell us where to put the line (I'm guesing a barb down on the intake by the turbo inlet ???).

I'm telling you what i was told to do with the breather line by someone else running a turbo upgrade and how I hooked mine up.

It doesn't mean I'm 100% right, but I haven't had no codes or ill effects thus far from doing a crankcase breather.

Why cmiller got so pissy about the discussion I have no idea, I never said he was wrong, just told u the way mine was hooked up.

If running a line to the intake is the right way for the breather line, I'm all about doing stuff the right way, but don't just give bits and pieces of information for people to try and figure how to do it properly, just tell them straight out what to do.

My only question is would running the line to the intake create a vaccuum or pressurize the line?

in my first post I said how I did it. I am not being pissy it's just the little black piece is not a pcv valve. You van take it off and blow through it. The braided line that is all the way to the passenger side is the one that will be hooked to the intake tube, the tube that goes to the turbo not the intake mani. The other line which is the one in the middle of the valve cover is plugged when you buy a ZZP turbo kit.

I answered your question in the first reply, either do it or wait till this thread gets to 100 posts and maybe you'll find another answer.

I would go this route if your decide not to do the crankcase breather filter (I've seen pros/cons to both methods over various forums), but in no way or form would i get rid of my PCV valve.
