What to do with the intake blowby hose?

[Mazdanspeed]

I know this is probably a dumb question, but the hose that goes into the intake delivers blow by and fumes that can gunk up the intake and valves no? SO is there any solution to this, such as routing it into a catch can or some other similar concept? Just trying to preserve the engine as long as possible. (breakn)

catch can?

I was thinking of that, but is there any way to integrate that hose into a catch that can be used for lets say, the pcv valve that goes into intake Manifold?

youd probably have to run 2 seperate cans. the one to vent the crank case is pressurized i believe and have two seperate inlet/outlet hoses would cause a wrongful airflow. 2 cans? my solution.

yeah you can't run them to the same can, you would need 2 separate cans.

Search "catch can" on this forum. There's a lot of info, including helpful how-to instructions and photos.

A catch can with second PVC valve is very beneficial on the line between the PCV valve and the intake manifold. This is where the real crankcase blow by goes.

Thanks for all the info, but i have one more question, would this catch can just be only the one blowby(flash) hose going in, with a breather filter attached to the can, or would it go into the catch can, let the the catch can do its thing, and then go back into the intake?

it would be a recirc. wherever the stock hose runs you just get two segments of hose that can withstand some heat and pressure and put it from the pvc to the can, then from the can to the intake mani. im not sure about the hose into the intake. ive checked mine and noticed it does have some oil running into it but never decided to do anything about it. let me know what you come up with and how you went aout it so i can fix this also. thanks.
