i have replace the o ring with one of the same size still leaked so i went to a honda dealer ship get one still leaking. any suggestion??? its the one at the end of the dizzy where it meets the cam

 

the o ring may have rolled when you slid the distributor on, did you lubericate the o ring and matchign space where it seals against the dizzy before installation? if not remove the ring, straighten it out, carefully reinstall it so its not twisted, and lube it then slide it on.

 

 

just put litt oil on it then?? thanx for the help
