porcupine73 Posted November 13, 2006 Share Posted November 13, 2006 My guess would be maybe one set is for the intake and the other color the exhaust? Maybe when the stop tears it down they/you can see which color is where in the existing stuff? Quote Link to comment Share on other sites More sharing options...

Never had an EJ engine that far apart, but I know that the EA82 valve seals are different heights for intake and exhaust. I can't remember if they're different colors or not. If your seals appear to be otherwise identical, it's probably a different rubber compound better suited to each application (the intake has to seal against vacuum, while the exhaust has to deal with more heat).
