MG MGA - Exhaust manifold stud threads
| I have what I believe is a common problem..the three exhaust manifold studs (exhaust pipe connection end) are very loose, caused by corrosion. Is there any way to firm these up, such as a helicoil or similar? |

| I have replaced all three of mine with bolts. |

| Yes, you can drill out the threads (keep it straight)and install Helicoils, then install new studs.  No need to fiddle with loose bolts and nuts. |
