There is an official Subaru modification kit to fix this problem. I do not know if it is still available.

 

Refering to this picture:

The kit includes the "T" at A, and the "T" at B, the plug at C, and the hose between them. This picture is after the kit is installed.

 

The original system had a small ellbow at C, a smaller hose from C to the "T" at B, and the original "T" had a smaller port. Also, an ellbow at A.

 

After installing this kit, I have never had the problem again.

Excuse me, please if I Ask a Dumb Question, but I Can not see Clearly it in the Picture, so I`ll Ask:

 

Now with that new Route, Both Heads Connect Together But with Two "T" Connections, at point A and B of your Picture.

So, Where Does the PCV Connects? ... At Point B? ... Then the Opening from Point A is Connected to Point C, isn`t it?

Yes.

 

So, Where Does the PCV Connects?

 

The PCV connects where it originally did, the tap of "T" B that is facing down.

 

The port C is pluged as part of the modification.

 

I added a link to a bigger picture to the original post. (I hope)

The kit is still available from Subaru (part number 11813AA010), however it's about $45. Scrounge around a junk yard and I'd bet some EA82's in there have already been updated with the parts you can swap onto yours.

Here's the setup before the update:

Here are the parts involved in the update:

And the setup after the update:

Just find one like that and grab the parts to keep your PCV/breather system flowing better

Thank you for your Kind Replies and Pics!

 

I`ve done a Different connection on my Weberized EA82...

I Hooked Both Heads together with a New 5/8" Hose to a "T"

and the Opening from the "T" goes to the Air filter`s Box.

 

The PCV is Alone with its Own 5/8" Air Filter.

 

I`ve done it Because the Oil Blown by the Heads was being

Swallowed by the PCV Valve... I`ve had No Problems with that

Connection but I Know that since the PCV don`t Breathe the

Gases and Fumes from the Heads, there should be some sort

of Toxics in the Oil...

The blow by gasses will be sucked into the intake because you routed the hoses to the air filter box. The only downside could be the oil vapors that get carried along could dirty up the Weber. If that isn't happening, no worries.

 

I'm not sure where you have the PCV valve hooked up. One side is to the manifold, the other needs to connect to the crank case for it to do what it was intended to. That would be control emissions. Since the other vents go to the air box, all the unburned gasses, etc, should end up going into the engine anyway.

besides the SPFI hose correction its also important to use a genuine subaru PCV valve.
