Live4Boost Posted June 12, 2010 Report Share Posted June 12, 2010 I am installing a new ovc with a greddy bov and everyone I see with a bov has a line running from the the top of the bov to somewhere on the driver side of the motor. Where does this line go and what does it do? Link to comment Share on other sites More sharing options...
InvolvedRotary Posted June 12, 2010 Report Share Posted June 12, 2010 That line goes to a nipple beneath the throttle body (there should be a trio of vac nipples in a row, I want to say the line hooks into either the first or last nipple in the row). The purpose of that line is to have a proper referance for vac/boost referance for the BOV and other related items. Link to comment Share on other sites More sharing options...
JAinsworth Posted June 12, 2010 Report Share Posted June 12, 2010 You need to tee the vacuum line into the back port of the 3 mentioned above OR the single port located below the 3. Link to comment Share on other sites More sharing options...
