How to Repair a G5 Quad Dual Pump LCS

Mhm... yeah... are you sure about it? And then, why putting them at all?
(I found they are useless too. I mean, I cannot see their functionality)
Another thing, when putting the screws with the springs (the one that attach the CPU PCB to that metal plate behind the copper liquid thing) should I tighten them until the screws stop?

I think they're there to add a little more pressure onto the block but they serve no other function. As for the screws, you can go ahead and tighten them by hand (with a screwdriver of course). Don't over do/torque them though! It's not necessary as it doesn't support that much weight and you might strip them or worse damage the CPU! I tighten them in a crisscross manner to insure a good pressure repartition on the die.
I too attempted this repair. But unfortunately in my case it was a failure. I think my heat exchanger is clogged or something because I'm not seeing a lot of flow and it sometimes leaks when I turn the unit upside down. I haven't lost hope though. Next time i'll try to run it with some sort of temporary reservoir (i.e. a bucket).

Thank you @BadGoldEagle
Anyway I saw the screws have a "limit” (you cannot tighten them in infinite) and that’s the reason why I asked. I’m thinking maybe they were not tighten enough.
About the o-rings... yeah but the pressure is between the copper and the little aluminum plate. Which is "unusual”? Strange anyway. But I’m thinking LOL if they were put there for assembly only.

I didn't say they had no use, I said it helps assembly when attaching the waterblock to the CPU.
Yeah, sure... but I expected something more "important"...
I’m going to replace them anyway though.
Just sent the same post two times... apparently I cannot delete it...
Since I am here... would someone explain me “what I have done” in the picture above? It was not me, but the old owner. I do not like it though. I am worried since it is the CPU PCB itself.

Hello again... I wrote a long post until the page refreshed. I’m very frustrated now...
Anyway I made the disassembling.
What I have now is this:
• the liquid was like water, no color at all...
• there was little liquid inside
• no @BadGoldEagle orange little balls
• what kind of hoses they are? Seems very strong and made with two materials. The inside is something like plastic, and outside rubber.
• What kind of glue it is? I need the same glue.
That’s all...

Hi guys, is there anyone here located in Europe who would offer do a Quad LCS service+CPU repaste job by any chance? If so what would be the fee? I would have one Delphi and/or one Cooligy one (I guess more difficult).
Alternatively if anyone knows of a way to top up a Delphi system without having to take the pipes off? Can the port/valve covered by a plastic cap (which can be unscrewed) be used by any chance, and if so, with what other hole/opening (it would take two openings I gather)?
Am also asking about repasting because no matter how well I try, CPU B always ends up being basically unusable, if anyone has any tips, would be great!
Cheers,
