Reusing Outer water seal O’ring

I’ am rebuilding a 13B Turbo motor
I got a few water seal that look like new
But that are all about 1-2cm too big
Dose any one knows how to skink the water seal back to the normal size? or
And has any one try to cut a bit out of the o’ring to make it fit
What are the chances of that working?

Thumbs down

If the seals have already been used then they MUST not be reused! The reason they are too long is because they stretched when being pulled from their original fitting. In addition, if they have stretched then they will be thinner, and will seal less well. If they have been used they will also be distorted where they were earlier compressed.
I think that reusing any flexible parts, gaskets etc is asking for trouble; when you consider the cost and hassle of removing and rebuilding an engine, then trying to save a few $ in this way is likely to be a big mistake
