318 LA Mystery exhaust leak SOLVED

[Boduke]

After pissing and moaning and swearing and f*ng with the ball flange and using muffler cement and ultra-copper and pulling the manifold and replacing the exhaust gaskets several times. I realized that the factory mustve put holes in the manifold to lube heat riser valve. I thought i was being slick removing it and welding up the holes but it appears i missed these two small ones. Just an fyi to save others blood sweat and tears

Yes they did, but basically no one ever lubed them. Kim
