First check the issue by putting soap and water around the plugs and starting the motor. Bubbles indicate leakage.

There are high strength metalized epoxies out there that can be applied and sanded.

Those UY-6 plugs don't need to be very tight. However, bubbles indicate gases are getting past the threads and that is a different problem.
