PSA: Do not forget to hook the PCV line back up

scalbert · 04-04-2009, 09:23 PM

As the title says, do not foget to hook it back up when installing an intake. You will have no boost and will also have no brakes.

Blue ring?? It is the line which runs over the snorkel to the intake box. You will know imediately when you forget to hook it up.

Funny part is that I have unhooked it dozens of times and never failed to hook it up. But I guess with multiple things being done and 4 girls (between 5 and 8 year old) asking questions every minute and running around, I got distracted.

i was told it had something to do with the brakes, guess not.

It is a common vacuum line. It does affect the brakes as well as the boost control system.

Would unhooking that line throw an evap error code?

It did throw an Engine Malfunction code but I haven't scanned yet. Will scan and post in the morning.

Are you talking about the line that has a connection near the oil filter and airbox? That's not for PCV. It goes from the Vacuum pump to the brakes.

ianthegreat · 04-05-2009, 01:43 AM

It's the line when you pop it off goes SHHHHHHWWPPP. Clearly a vacuum line.

gian335 · 04-05-2009, 01:45 AM

its the line that is kinda right over or nearest to the intake.....if u forget to hook it back up ull know what u did wrong right away....the brakes dont work the best lol thats forsure.

you'll need a concrete foot to handle the brakes with out it hooked up

TMR · 04-05-2009, 01:51 AM

I learned the no brakes issue today... LOL

RiXst3r · 04-05-2009, 04:31 AM

Yep

XPO186 · 04-05-2009, 05:03 AM

LOL!!!

I forgot to plug mine in a couple of weeks back... doing a boost gauge install of all things!!! (needed a bit more access to the vacuum lines on the DVs)

Basically... no brakes and smelly white smoke pouring out of the exhaust.

Definitely NOT FUN.

Italia335i · 04-05-2009, 10:49 AM

Been there, I knew I missed something as soon I as got to the first stop sign....

I had no idea it affected the brakes though. So unplugging that line could make for some interesting pranks..................

damn, wouldnt wanna be one of your friends haha

no brakes = prank?
