Actually SpaceX has stated only CSR8 will be able to refly at this point, the other 2 returns have to much damage but will be good to study

If it was leaking they would've lost pressure and the fins wouldn't have been working on landing.It is not a closed system.We know, it's RP-1. If it was leaking they'd run out and it would be CRS-5 all over again

Did manage to download the pic. Does the top of the stage look a bit buckled to anyone else?https://www.instagram.com/p/BGKRcY3F8XC/Edit: First line changed and picture attached.
In fact, I don't know how safe it is to say that the residue is hydraulic fluid, it was speculated before it can just be the TPS on the fins peppering the interstage... although its distribution does make it appealing to give credence to this possibility.
That is: this is what the open loop hydraulic grid fin system looks like after nominal operation. No "leak" other than the designed-in exhaust port.
Also: "open system" means precisely that the fluid is exhausted out some port after use. Although there was speculation that they'd try to recapture the exhaust into the main propellant tank if the working fluid was RP-1, I think before Occam's Razor would point to these pictures as proof that the exhaust is dumped overboard, as most experienced hands had thought would be the case.That is: this is what the open loop hydraulic grid fin system looks like after nominal operation.
