Valve Cover PCV & ECL

[Anthony Yacullo]

So my check engine light is on and its an o2 sensor, and I also have p1105 (barometer something). Not sure what is wrong but it does idle different on start up. I also have no breather hose coming out of the valve cover, I just picked up this car and never had a hose. My questions are could this be causing p1105 and where does the hose hook up to, I know its somewhere on the intake but I can't seem to find it.

The open nipple on the valve cover will need a vacuum line going to your intake pipe just below where the bypass valve recirculates back in the intake. That source to the valve cover needs to see vacuum to relieve pressure which is why it goes to the intake (pre-turbo).
