My 93 240sx (ka24de) 's has failed HC emissions. the plugs are oil soaked is this a sign of anything more than valve cover gasket,and would this fail me?, i heared 240's are sensitive to any other plugs than NGK(bosch platinum in now) any insight to any of this would be much appriciated! thanks, adhd
