it appears to be such a rampant issue for people including vette, camaro, caddy v series, gt350 ... weeping around the threads.
Mechanic or otherwise, i just doesnt make senese. i pulled a few bleeder valves, and they look fine. no scoring, no thread damage whatsoever.
i'm going to blast them to some brake clean, maybe add some high-temp thread sealant and see what happens.
wondering if anyone else has experience with this a the torque value they used to solve the issue. i've seen a few post from reliable people alluding to needing more torque than they expected. wonder how much

Hey Mike, well, I hope you're able to solve yours without a caliper replacement!
I went through several stages on this, which included doing some maybe silly things to just make sure it wasn't that. That included replacing the bleed screw twice, and changing how much I tightened it. I tried cleaning out the plug hole and plug several times, etc. In the end, it always had some level of weep past the plug. I gave up and ordered a new one that I'll hopefully put on this week.
As for damaging easy, I don't know. Despite my "analysis", I bet I wasn't paying attention and leaned into my ignition wrench and torqued the heck out of it. I don't know but I think our calipers are (cast) Al and honestly not sure about the plug screw. But someone else said maybe the screw is steel, so in relative metal hardness, it might not be that hard to damage a seat. I just was warning that you might want to use a torque wrench, so you at least know consistently what you are applying, whether within the spec or not. Given my experience, I have lost faith in myself to trust that i torque it consistently each time and location... Good luck, let us know if you solve it without replacement.
BTW, not so sure i would try sealing with the threads, at least that is me.
Edit: on mine, the plug still screwed in easily by hand, so i also suspected it wasn't the threads.
