After replacing the delivery valve orings the car seems to idle on the loud side. What could have caused this ? Copper seals?

Or you didn't torque it correctly? Use the Search feature above, find the numerous threads about replacing the delivery valve O rings and seals, and the sequence for torquing them. And some comments about noise afterwards.

Very common to have a noisy idle after replacing DV orings and crush washers. Especially at cold idle. Is my belief that no matter how clean one is performing the job that some rubber particles remain in the valves wells and when reassembled end up in the inj's.

DP and miles driven seems to be the only remedy; assuming everything went well during replacement and nothing was installed incorrectly.

Are you sure your mind isn't playing tricks on you?

I thought the same but actually its no different.
