Yep - get a new gasket from Honda - only a few quid £4.75 I think.C&S Evo7 said:you need to remove the throttle body to get to the iac valve,
sometimes the original gasket is ok but not often, its the same as a civic so no probs from honda,
beware you cannot buy the valve separatly from Honda.
Contact Tom at TGM for a J's Racing or Spoon replacement which i think are cheaper then oem.
