Crawford AOS with FBM kit - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

whitefrs · 06-29-2013, 07:13 AM

So i decided to go with crawford AOS and i was doing the installation when i notice that my throttle body pipe has no port to connect to the top port of the AOS.

Is anyone running this with a fbm kit?

What can i do here?

top port can be vented to atmosphere. just run a longer house down to bottom of engine bay.

Yes you should. Under vacuum this port is pulling air into the crankcase.

This is what crawford told me

Safe is not the correct term Wilbert, its not like the motor will blow up from the crankcase vent being open but its just not proper. If you leave it open then you will not get a negative pressure on the crankcase which will make the piston rings not seal as well, plus you will smell the nasty burning oil smell constantly coming out of this hose.

I would just plug that port on the can, or if you want a hose to run to it, then just T the hose off the back of the intake manifold and run it to both ports on the can. I will stick with my vented catch can.

Just bung ur intake pipe drill it and get one of those plastic taps with rubber seals and connect the hose

@Gen has the FBM with a Crawford AOS. He should be able to chime in.
