ThreePer 36 Report post Posted September 20, 2018 Yup the new seals are good. Expensive, but good. The other plus on 254 is that if your turbine is prone to N2 lockup while running Jet II then the 254 will usually cure it. It did on two different C20 powered machines we recently acquired. And lastly, 254 glows bright green when you shine a ultraviolet light on it. So if you are leaking just dim the lights and buy yourself a cheap ultraviolet flashlight and follow the bright green trail. Quote Share this post Link to post Share on other sites
