    • oil lines ran
    • driveshaft and diff spacers installed
    • brake reservoir mounted
    • started trying to figure out engine harness routing
    • installed (and removed) heater hose connections at the firewall. I wasn't happy with the interference with the engine, so I'll have to redo them.
    • decided to ditch the braided lines. I started making NiCopp hard-lines for the master cylinder connections. The Mastercool flare tool makes it easy.


    Everything looks like a complete disaster, but hopefully things will start cleaning up soon.

        That's how it is. The mounting flange on the diff is offset to the passenger side.

          Is that how you are going to leave the steam port vent line thing?

            Pretty much...

            I still need to run a line from the junction block to the radiator fill neck port. It's not the prettiest thing...

              This build is too clean to leave it like that. That is something I would expect in my build lol

                Haha.

                There aren't a lot of options. In order to function properly, it needs to be the highest point in the system. I could just not run it though...

                  You could run the under intake one. It isn't that essential of a system. Just make sure the motor is bled well

                    The under-intake version doesn't seem to work with the ls3 style intakes. Motion Race Works sells a side mount one that's marginally cleaner.

                      I have a long term plan to mount the pcv breather. I'll be getting a license for Creo through work soon. The plan is to design a nice solid mounting bracket that I'll either print or have machined. In the interim, I made a quick and dirty mount to keep things moving.
