calwood1kid Posted May 27, 2007 Share Posted May 27, 2007 Just had the head rebuilt on my 37 Roadmaster. AS I am getting ready to assemble and install the manifold, I am wondering what seals the 3 piece exaust manifold at its joints. I also had the carb rebuilt. It is sloppy just above and idle but otherwise is find. Any input will be appreciated. Thanks. <img src="http://forums.aaca.org/images/graemlins/confused.gif" alt="" /> Link to comment Share on other sites More sharing options...
Guest DaveCorbin Posted May 28, 2007 Share Posted May 28, 2007 Dear Calwood: Basic short answer is: nothing! That joint is supposed to slid back and forth a bit as the manifold heats and cools. It does want to be a very close clearance fit when cold. Just be sure that nothing is cracked at the center section pice. What it does do is fill in a little bit with carbon as the engine runs.
