I installed a rope seal in an assembled engine. I took all of the main caps off, pried the crank up high enough to remove the bad seal. Then I worked the new seal in. Once I was sure the seal was sitting in its grove, I tightened the front 4 main caps, which packed the seal in. Then I just trimmed it, fit the seal in the main cap and finished up the engine. It might not be the correct way to do it but it runs leak free. If you are using a rope seal, a Best seal is the only way to go.
