Double Checking
Yes its another emission removal thread. I've search and read the majority of the emission removal threads on here but I'm just wanting to double check on the work before progressing on. First off most of the things are block off except I'm keeping the Cold start assist (no TB mod), BAC, Twin scroll, and Charcoal Canister. I've based most of my lines off this three pictures from the forum members. I just want to know if the vac lines are in the right places.
UIM Manifold nipples close to firewall: Top to Bottom
1.Top nipple goes to LIM nipple between oil injectors (close to primary injectors).
2.Middle Cap off (removed OMP).
3.Lower nipple connects to inner of TB nipple with check valve pointing towards the IM.
UIM Manifold nipples far from the firewall: Top to Bottom
1.Top nipple goes to Twin Scroll Solenoids' top nipple, from Twin Scroll Solenoid (blue) back nipple goes to a check valve facing the IM and from the check valve to the Switching Actuator.
2.Middle nipple goes to PCV top nipple.
3.Lower nipple goes to small nipple on PCV and the PCV big nipple goes to intermediate housing nipple.
UIM back nipple next to BAC goes to a 3 way nipple, 1 leading to the pressure sensor which I believe comes with a "restrictor pill" (mines looks red when I looked at it), and the last nipple goes to the Air Bypass Valve.
FPR (the nipple on the secondary injector rail close to firewall) goes to the top nipple of the Pressure Regulator Solenoid (orange), and back nipples goes to the nipple (only nipple facing the firewall) close to the sub-zero (mines doesn't have sub-zero system so I didn't have to block it off).
Oil filler nipple goes to a 3 way nipple, 1 goes to the Turbo Inlet Duct and the other to the Charcoal Canister.
I've mostly followed the multi color diagram for the piping and compared it to the other two pictures. If theres anything wrong with this please free to correct me.
