Thread: HOW TO: Reroute Oily Blow By Gases to Clean Up the Intake Manifold

The capitalist has the correct answer, hehe.

# About 2 Feet - 5/8" Hose (Needs to be able to withstand high heat, I used Power Steering hose $3 a foot. Heater Hose will not withstand the heat!)
# About 1 Foot - 5/8" Heater Hose for Intake to Oil Separator. The reason I say you can use heater hose, because even AEM used the heater hose for the Intake to VC.
# 1 - 5/8" Hose Tee (Something stronger then emissions T is advised, but hard to find)
# 4 Clamps
# 1 - 5/8" Rubber Cap


I've used the emission hose [made for oil] and it worked well. Heater hose is not made for oil in the long run

For the tee, I went with a brass tee and had zero problems over the last year

Heater hose also expands when oil gets into it. I used power stearing hose for the main parts, it's just expensive, big, and doesn't move easily.

As for the T where did you find the brass T? I have the heater hose T and it works just fine.

BTW guys, I will be updating this How To, after a very good discussion with BenFenner, I've came to a conclusion that this is not actually a very good way to reroute them.

Danke!! jiji

The brass T can be a 3/4" barb T from home depot's plumbing section. It fits, trust me.

Any new info on this?

Yup two catch can's.

I've actually been driving with the way it is setup stock, and I've had much less oily blow by.

You basically cannot get around this without having two catch cans.

so what your sayin is stock set-up
1 catch can for the pcv
another catch can for the intake

Basically yes. The problem with having the VC go below the catch can is, the crank gas from below will go into the VC.

I'll have some pictures later on.

EDIT: Ben helped me realize that I said yes to only two catch cans. Basically what you want to do is actually have 3.

1 for PCV, this goes between the Intake manifold and Valve cover. If your boosted, make sure catch can can withstand boost.

2 for Valve cover breather/blow by.

Oh lord no...
