result:
it doesn't matter which injector is attached to a particular port/hose - it leaks at rest every time

Then it appears the fuel distributor must be replaced or rebuilt.

thanks Dave!
I think....I had to adjust the CO adjustment to extra revs....is the opposite possible? i.e. the bad injector spits a lot because of the extra CO regulation, so the problem is the other 5....I don't know. very strange that the negative adjustment has no visible effect....
I've only rebuilt one FD. There are a lot of small holes that need to be clean inside the FD. But my guess is your leaking port probably has some "dirt" on that thin metal plate so it can not seal. If I was to do another FD rebuilt, I would not use anything to seal the two halfs and make sure everything is super flat and clean. The factory did not use any sealer. I would lightly sand the halfs on my granite surface block to make sure it's flat.
After you fix this, be sure to change the engine oil. no doubt it has been contaminated by the excess fuel, got thinned and will not protect the engine properly.
I bet that if you pull the dipstick, it will smell like fuel.
Thanks a lot for your valuable advice. I'll check the whole system. Thanks so much
