I had installed a trex camand pac sorings in my ls1, upon getting it running i noticed some smoke. the valves stems were marred right above the valve seals, i emory clothed them down and replaced the bad valve seals. what would cause this? has anyone else had the same problem? the only thing i could think of is i tried for a while to get it stated and wasnt getting fire and may have not had oil on the valves??
