Get a replacement.I use these in the fresh air tubes for my vehicles PCV systems and have seen a notable decrease in oil consumption. ### ⭐⭐ Not metal *by T***N on Reviewed in the United States on September 26, 2020* Didn’t expect these to be plastic painted to look metal. ### ⭐⭐⭐⭐⭐ 6 Months+ usage-Automotive Usage-oil catch can installation-2015 Hyundai Veloster Turbo *by I***C on Reviewed in the United States on March 10, 2020* Automotive Usage-oil catch can installation-2015 Hyundai Veloster TurboI’ve been using this for about 6+ months, no issues-the barbs on it helped to secure the vacuum line.
