Soniq7 Posted December 10, 2004 Is my 400 supposed to have one of those copper "o" rings in between the cyl head and the pipe? There aint one in there now.. Share this post Link to post Share on other sites
Noble Posted December 10, 2004 There is a gasket but it is not copper. Look close. I don't think the pipe would even tighten up to the head without the gasket. Share this post Link to post Share on other sites
