ok too start off it is a 91 ka24de. i need to know what the part is called behind the oil horn, it is a ball with a spring behind it dose anyone know what this is called or have a part number? Pluse one more thing, what is the vacum lines that under the intake an go to the bottom of each intake runner. Can i deleat this, i want the least vacum lines as posble because i am going to be running 20psi of boost an want the least possble things that can leak.

Ok i found out what the part is, its a oil bypass valve assembly. But still need to know if i can deleat those vacuums.

Anybody?

That would be a part of your PCV system.
Unless you're going to redo the way it's routed, I wouldn't remove it.

Yeahci found a sweet a** read up on it after lookn for three hours. You can take it off an block it an just vent theought the vavle cover. Realy if you run 20psi of boost you should takebit off cause you take the chance of preesuring up your block.

The old factory pcv doesn't like 20 psi so much...lol.

No it dont at 12 psi on my old on one it would put a bit of pressure in it.

dual can ftw
block off stock 4:1 pipe steal a large vac source run to check valve(already one at box on timing cover but meh),from check valve to catch can, from can to oem crank case baffle box.

vc to can ,can to pre turbo.

Just blocked it off. I am going to let it vent out of the v cover.
