I have reguarly made o rings using o ring cord, a sharp knife and instant glue. Got me out of a hole a few times at work but really only works best on larger diameters. On smaller diameters it is hard to get an aligned joint in the o ring.
I am not suggesting that you tear down your non leaking bike to try this out though.

All opinions are given with no warrenty, expressed or implied!!
I tear it down every year anyway.
Fresh coolant and quick flush for the peace of mind. (and a complete 'gotrough' maintenance wise)
But if this holds up im just gonna use the method i am currently using. It's a guaranteed seal on the first try.

Unless you can give me that warrenty! Thx for the tip tho, appreciate it.
