Its completely normal, mine did the same thing. Itās ok for a little of the residual pressure to bleed off when opened.Just installed the HPS screw. Noob question though, when I unscrewed the OEM version while the engine was cool, I heard a little hiss with a rush of air. Iām assuming thatās normal because itās a pressurized or closed system?
yeah, I was the one who begged them to make the coolant caps,Oh snap! Titanium coolant caps. ??

Yes, they have failed under normal driving conditions. The screw itself is flawed. They cored out the center of it just below the philips cross. And then they added a small notch along the threads. The wall sections in that area are thin.Is there even a chance with the stock one failing if it's never touched?
Do you have any photos of it failing. Some of my a90 Supra people donāt understand the point of it being replaced. I just like the bling! LolYes, they have failed under normal driving conditions.

The screw feels like its made of ginger bread, it weighs almost nothing.
