So I was cleaning my GPU block and left the biggest o-ring in water that was a little too hot. The ring expanded and now it's too big to fit into the block. I placed it in my freezer for 4 hours. Still too big. Being that I need to have this done this weekend, I cut the o-ring to size and used clear waterproof silicone to bridge the gap where I cut it. Had anyone done this before? My plan is to keep this temp solution for one year. At next annual cleaning, I will purchase replacement o-rings. Is this just a bad idea?

Its a bad idea. I did the exact same thing with an o ring for the heater core on my camaro. Leaked almost immediately. The heat will separate those 2 items and its sure to leak.
For the record, the silicone idea worked perfectly. I leaked test for 26 hours and absolutely no leaks from the block.
You know, I prefer a new o-ring and the silicone haha

I accidently crushed ~1mm of an O-ring in my old block which cause it to crack. After using a razor to clean up the edges and supergluing it back together I never had any leaks. Of course, the reason it got crushed in the first place is because it was slightly too long - making it just the right length after the surgery.
