On 3.8 fuel injectors there is a o-ring on the bottom where it fits into intake. There is also a thin ceramic or plastic ring what is its purpose. I replaced upper intake plenum gasket because of water leak. I was going to replace the bottom o-ring on the injectors and two of the small thin rings just fell into pieces. What do they actually do. Thank u
have the same problem?
