Hi Guys
there is a tube which goes to the air intake, can that be blocked off, is that to bleed of crankcase gases back into the combustion chamber via the air intake?.
could i run a catch can instead? because i think this is for environmental purposes and my car is mostly on the track.
thank you
crankcase tube to air intake
Re: crankcase tube to air intake
If you're talking about the tubes that come off the valve covers then yes you can send them to a catch can. Later versions of the K engine eliminated those vents. I'd still run the line off the PCV valve.

Yes the hose circled in red, i was about to upload a pic but I still have to search the site and see how to do this.
Should i Run a catch can or block it off?
does it affect performance of the vehicle?.

Re: crankcase tube to air intake
Its purpose is to introduce fresh air for emissions. I believe you can bypass this hose all together though, but someone else jump in to confirm. I've seen some people put a small filter on this hose as well.
Re: crankcase tube to air intake
I have that hose vented to outside air, as my current intake setup has no hole for the hose. Texas emission have a bunch of grey areas...
IIRC that hose helps pull some PCV from the valve covers and burn it inside the motor.
