What's the purpose of this vacuum line...

What's the purpose of this vacuum line and does it need to be plugged up the same way when I run my hardpipes when I put my turbo on? Thanks.

It's the positive crankcase ventilation (PCV) system hose.

 

[hellcat]

Yep, just a vent for your valve cover

 

[P-Funk!]

Don't plug it!

so if I leave that in the intercooler pipe it will be ok.

i wouldn't put it on a pressure pipe, i would run it to the intake pipe.

You could put one of those little fuel filters on it...

looks more like a small conical air filter to me. Is that what yall are talking about? Thanks

and by the way, does anyone know where the best place to put the air temp sensor is on a boosted application? thanks

Doh...you're right. Bonehead thought on my behalf, heh.

you can put it in the fender well, as some have. or put it in the pipe near the maf. drill a hole w/ grommet or something.

For boosted - you would 'have' to put it in the MAF air stream. For me (SRI) ambient engine bay temp=air inlet temp.

some people put it in the fender well. evidently there's a hole that fits it perfectly.
