Seafoam cleaning port for Mini Cooper vehicles

thingiverse

Turbocharged engines accumulate carbon in their intake systems, as well as on the back of the valves and MAF sensor. This can lead to significant performance issues and large maintenance bills. To address this problem, a simple device is installed in the PVC vent line located at the rear, passenger side of the valve cover, which leads directly below the throttle body. The installation should be done with the spout facing upwards. I opted for the solid version and secured it to a Schrader valve body using epoxy, allowing me to cap it with a metal valve cap. The solid arm was then drilled to accommodate the red tube from an aerosol can of Seafoam, which can be used while the engine is running. For those who prefer to use liquid Seafoam, there's also a variant with a large hole, requiring only a paint cap and a small hose clamp. YouTube offers numerous videos demonstrating how to effectively utilize Seafoam in Mini vehicles, both in aerosol and liquid form. Special thanks go to zacharylaynewilson for creating the STL files. I printed this device using ABS material at high resolution with a 0.2mm layer height and solid settings, resulting in a remarkably strong product. So far, it has performed flawlessly; however, I may apply an acetone finish to eliminate any potential porosity if necessary, possibly to prevent oil seepage.
