Frequently Asked Questions

If your Synchronic BOV started sounding different all of a sudden, we recommend removing the back cap by removing the 6x hex cap screws, and inspecting the smaller diameter preload spring for any binding or breaking. The unit will function fine without this preload spring (especially if the preload adjustment screw was being run in the factory position). Try removing the smaller preload spring, and see if that fixes the issues you're having with the blow off valve. In certain cases, the preload spring may break, and bind, interfering with the normal operation of the Blow Off Valve.
