The O ring should give you a perfect seal, so long as it and the cover can be tightly squeezed up when the screws are tightened.....with a dodgy thread insert, I can't see how that can be happening!
I'm just concerned about the safety issue here.....after all, silicone wasn't used in the product originally.
