Thanks. It does look fairly straight forward. I would prefer to get two new copper gaskets rather than doing the annealing thing. I hope I can just take one to the hardware store and match it up.I was going to point you to Tony's how to...I'd say that's your answer.
Thanks, Henry. I verified the no-reuse of the washer philosophy - ha! I tried heating them to restore their softness but it didn't work - I still got a very very slow leak at ambient pressure. After a few days it stopped leaking - but I didn't trust it. So, I drained the coolant yet again and put new washers with Rectorseal Tru-Blu and tightened it all up. I am waiting a day to add the coolant so the sealant can cure.The copper washers are crushable and considered a one time use item, like a gasket. Sometimes you can break the banjo connection and reuse the washer, but they will eventually leak. Once they start leaking there is no fixing them.
I've worked with them only on fuel systems, so I always kept a supply in my tool box and just tossed the used ones.
I'd suggest contacting your dealer and buying a supply. You can try and find them at an auto parts store, but it's a long shot.

I bought mine directly form a Cummins dealer. Pretty cheap. I think I bought 6 to have enough for future use. I tightened the banjo until it was good an snug and then give it one last for push for a final crush of the washer. Hasn't leaked since. I did use the Rector Blu sealant.I realize that this is an old thread, but I thought I'd give it a try. I found my banjo fitting on the Port Turbo leaking coolant. A small leak, and it has taken me a while to nail it down.
As a first attempt to mitigate the leak, can I just "tighten" the banjo fitting? Or will that create more problems than it will solve? I'm going after the T-Stats next month, so I will have a perfect opportunity to fix it. Can anyone supply a source for the copper washers?
Thanks,
