The Blue Devil has fixed the leak. Blue Devil claims a "permanent" fix and no need to keep the leak stop in the system after the leak stops. I have flushed the system and put in new A/F. Leak has not come back.

I will monitor this but so far I can attest to Blue Devil working. This saved me a ton of extra work.
