Ever look on the internet on how to repair a pop valve? Never find it. We decided to show you how to change a Retsco Titan 3" Pop Valve. We changed it once already & tore it apart to show everyone what we learned. Recorded with the Go Pro Hero 2 & had to use an I pad to ensure the video was good (permits & gas detection was present). Should have used smaller punches & a custom socket to remove bottom nut, but I will aim to do better next time. Let me know if you have any other ideas for future videos & feel free to leave comments, good or bad.
