Fast 90 Intake Install Help
I have searched and have not been able to find a definitive answer to a few nagging questions. When installing a Fast Intake what needs to be done with the passenger side valve cover breather tube as it has nowhere to go on the LS2 TB? Is it safe to cap it or does it need to be re-routed to another area for crankcase relief? Is it safe to drive with the tube capped as it sits now?
Any help would be much appreciated.

The tube on the passenger side valve cover is for fresh air introduction via the throttle body. Since the LS2/LS7 throttle body does not have a port to connect that line back up you can simply cap the valve cover port and run a breather-style oil cap to get your fresh air for the PCV system. I am among many others are doing this
. Doug at ECS recommended it to me.

Here is where I got my breather cap.
Oh and with the valve cover line capped (for now) your PCV system will not have a fresh air source, so the crankcase vaccum will try and suck air in from the front and/or rear crankshaft seal. I don't think I would drive around like that. Get yourself a breather and enjoy your new manifold & throttle body.

I'm installing a FAST90 next weekend. Glad I stumbled upon this thread.

Just to let those interested know, I ended up using a tee from one of my catch can hoses instead of the breather since I couldn't find one that would fit by this weekend. It works perfectly. I used the hose that goes into the valley cover from the catch can. I hope this makes sense to everyone. If not I can take pics it it helps.
