I have had my heat exchangers off and on now about 4 times, trying to make sure that they are seated and tight. I have checked the copper gasket, put in new ones and still I get popping or back firing on decel.
Tonight I pulled the driver's side and flat filed the tops of the HEs to make sure I have a good surface. Nothing drastic, just trying to make it flat and smooth. Is there any trick to getting everything buttoned up properly? |

(IMG:style_emoticons/default/agree.gif) Popping out the exhaust does not necessarily mean the HE to head junction is leaking.
To answer your question, you remove them from the head and use a propane torch. I always re-anneal the copper gaskets before installation, even when they're new. I make up a coat hanger... hanger for the gaskets and stick it in the vise. If your gaskets have any ridges on them, toss 'em and buy new ones. They're cheap... |
