| Saw several references to leaky exhaust manifolds in the last digest. Haven't you guys ever heard of Permatex Copper? 1. Remove manifold and clean surfaces. 2. Coat one surface with Permatex Copper. 3. Install manifold and torque bolts. 4. Allow drying time. 5. Forget about it. I used this stuff on my 429 ten years ago and it's still holding strong. |
