Default J's Catch Can With OEM Intake

For those with the J's catch can installed with the OEM intake, where did you run the hoses to? It seems that the following pic shows where the two hoses should be ran to, correct?



One mounted on the valve cover and the other on the intake manifold?

Thanks!

Ryan

SSmugen had traveled out to J's Racing Japan back in 2002-2003. He went out to Osaka to check out new parts back then and to buy some products while he was in Japan.

Anyway, one thing he did look at and ask them is the full installation on the Js can. They informed him there was a couple ways to do this.

They said for a street and daily driving application you only needed to use the front connection from the valve cover. The other one you leave alone. That way you get the very (almost nothing) blow by oil that comes out during your daily driving and you have the other connection on the can and use it as a dump off. So thats how a lot of us used it since we daily drived the car and for the fact that J's Racing Japan recommended this

I saw that pic, but where does the following hose go to? It usually connects to where the hose on the valve cover closer to the bottom is?!

What do you mean by capped off? The piece on the intake is soft plastic, so it flexes.

they cap it off at the metal end close to the VC so it kinda looks tacky. I was just looking at a hyper rev mag right now and some tuners do this:

So the picture in the first post isn't suggested to run it that way?

thats the common way ive noticed also. they run the two lines into the one line on the catch can. it has something to do about flow and idle i think.

i would contact Ben at A&J to get his opinion, there a a few different ways to do this, depending on the application and use.
