BronsonA2150 Posted 2 hours ago Share Posted 2 hours ago Called Mack and they were no help. Anyone know what exhaust and intake valves should be set at? As far as jakes go, which I believe mine are Jacob’s, I could look their specs up but has anyone found a good setting for them that might be different than factory? I know on the old mechanical 3406’s specs called for .070” but people figured out .090” worked better Quote Link to comment https://www.bigmacktrucks.com/topic/75855-94-e7-valve-lash-and-jake-setting-specs/ Share on other sites More sharing options...
