My 100% Functional 3D printed Blow Off Valve
Finally got around to modeling and printing a blow off valve spacer for the Ford 2.0L and 2.3L engines.
I didn’t have factory drawings to work from, so this was a lot of measuring, test fitting, tweaking, and learning along the way. The goal was to make something that keeps a clean bolt-on fit while adding that sharper turbo vent sound.
It uses 3 M6-40mm bolts and two O-rings:
1” OD / 7⁄8” ID / 1⁄8” thick
1 3⁄4” OD / 1 11⁄16” ID / 1⁄16” thick
For anyone printing it, I recommend ABS at a minimum since it lives in the engine bay. Supports are strongly recommended for ABS, and I’d stick with the wall settings provided with the model.
Pretty proud of how this one came together. It’s always cool taking an idea from “I think I can make that” to an actual functional part.
