Hello All,

This was the biggest problem I had when putting in my big turbo upgrade.
It took a little trial and error to get this right. And I know a couple people have had this issue, so I made a diagram for those to use as needed.

So can I cap off both lines coming out of the solenoid on the valve cover. I know one runs to the old bpv amd the other was for the boost side. Now I currently jave both the hard vaccum lines dangling.

Can you run the old BPV hose to the new BOV if you are already using the symposer delete nipple?

what is the other option if you are already using the symposer delete plate for an aftermarket boost gauge?

Just get a tee and tap into the line.
:whs: That'e exactly what I did on mine. Grabbed some "Ts" from Autozone. Unless you work at a machine shop and can fab up a block. CPE has one if you feel like dishing out $150.

So I should be able to tap into the symposer delete hose for the BOV and continue running my boost gauge off it as well if I understand you correctly

Is the diagram in first post accurate? Or can you eliminate both lines coming from the engine? There were a few posts above that appear to say you can, but just want to make sure as I’m in the middle of this step now.

If you do eliminate both lines, do you also eliminate the T fitting and run that side directly to the hot side charge pipe? Thanks
