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. |

Did anneal the gaskets.
It makes a huge difference. Not sure why not everyone is doing this. After fixing the leak on the driver side a leak appeared on the passenger side. To find out that the threats were stripped. In one spot the PO had installed an Allenbolt instead of the stud. This bolt engaged no more then 1/4”. A Helicoil tool is on order to correct this problem. Question: can I expect this Helicoil to take the torque needed to seal the exhaust manifold? Just asking because the Helicoils are not as long as the original threaded hole. Lots of threads here showing people doing this repair, just didn’t find the confirmation that it’s strong enough. |
