M273 Ignition Coil Screw stripped
Hello!!
Was just starting a leak down test (did cylinders 1 and 5 and happy to post photos, will make a separate thread) and found out one of the ignition coil screws, the top one on cyl5 if I remember correctly is stripped.
I have a brand new digital torque wrench and am extremely conscientious so I'm fairly confident this was the previous owner (they beat this thing up).
Was wondering what you all suggest moving forward since I have new spark plugs showing up tomorrow. Retap larger or is there some way to repair?

there are fancy solution like "threads insert" that can be ordered.
One of the two screws of the coil bring up GND to reference the secondary side of coil that fire the spark.
good luck fixing this.PITA.
🤞
