96 850 turbo TCV Line diagram help

Post by jakethesnake »

hey forum,

so looks like someone had the tcv lines hooked up wrong and I'm trying to piece together correctly.
I have the diagram in front of me and i can't figure out where the red line (part 20) plugs into.

Thanks

that is the compressor bypass line it goes over to the the intake manifold tree. It sends boost pressure over to open the CBV mechanically depending on the spring installed, 8 pounds of boost stock. its function is to vent boost if you suddenly see a cop during high boost but before the waste gate can dump.
