i have a hairline crack in my oil pan that needs repair or replace, and of course i had to drop the headers to take it off. Now since my headers are on the floor i figure thi is prime time to knock those blasted honey combs out. alredy have racefit can so id like to finish the deed. i have searched and cant find anyone who has done it. if there is... what did you use to knock them out? any input would be helpful before i start wailing away with my 4lb hammer!
