[RESOLVED] Home Depot Racing Husky catch can

[2GturboTALON]

I have seen a couple threads but no one truly answers which way is better to have the arrow (airflow) facing with these " catch cans" . I know that under vaccum it pulls from the intake but under boost it reverses the flow back into the intake. The only valid post i have seen says to point the arrow towards the VC . According to dejon tool they say when using their "crank vents" , (which seem like a similar idea to the compressor catch cans), to flow them away from the Vc, ("The small one goes on the valve cover vent to pump air out (not in)"). Can someone please clear this up because i just ordered my check valve from US plastics and want to make sure i get my catch can setup correct.

Arrow should point away from VC.

+1 ^^^ and not that there's a check valve to really makje it matter, so that's the more important thing to worry about (unless you're does have a check valve in it) can you blow throughy it in both directions? If so you need a check valve seperate from the can to keep the turbo from blowing boost back into the VC

PCV valve does not see boost, so arrow should be pointed away from valve cover into intake manifold.
The side vent sees only vacuum so arrow should also be pointed away from valve cover.
