So an old Honda SOHC guy I know told me about a head gasket trick that supposedly works; find a nylon bungee cord that is of a proper length and diameter to fit around the motor and stuff it between the fins, and ride it, cord melts, seals gasket, and then cut or scrape away the excess. Hs anyone heard of or tried this? I'm at the point where I'm getting a little oil on the pants, but don't want to pull the motor until the season is over. Any thoughts on why this would or would not work?
