Car didn’t pass inspection because of an exhaust leak.
So... Just ordered some manifold gaskets from Pelican Parts. Question is. Is this copper soft out of the box, or does it need to be annealed before install? Thanks for sharing your experiences. |

Perhaps not ... but it sure would never hurt.
The gaskets are press stamped from cold rolled copper. As mentioned put a long file along the mating surfaces so that the 2 ports are level and flush. Use a torch and get them red hot. The difference is significant. |
