I have one of the newer copper vein Grands. This morning I went to fill it up before work and there was juice on the top of my battery. So I unscrewed the delrin block from the top and noticed that the center pin of the connector had sunk down. So I try to push it up and it seems like the center pin is now free floating and allowing juice to seep into my REO. Amazingly, I have not had any issues with shorts and from inspecting it, the insulator does not look damaged in any way.. it's just not making a good seal around the center pin anymore. Has anyone had this issue? I was tossing around the idea of getting a rebuild kit from Rob or sending it to him. I have no problem replacing it myself if it's cheaper.

Edit: I use A7s on both of my REOs

I have no experience with this specific device, but your problem points to a blown o-ring, (it's the first thing I would check during troubleshooting). An o-ring can appear to look good when in fact a small rip may be hidden by limited view during inspection while still in the device. I would remove it and manipulate and bend/twist all along it's circumference making sure that nothing sticks out or that rips don't become visible upon manipulation. Examine under magnification if possible. O-ring tears can hide when they are in a relaxed condition.

Depending on the material it is made of and due to heating and cooling, it could also be that the o-ring is streched a bit and has lost it's memory, not fully returned to it's normal size.

There is no O-ring in this spot but it does sound as if there is too much play in the insulator gasket It may need a new gasket before it shorts out on you :)

Thanks for the replies guys. I have built several mods myself, so I definitely understand the insulator. This is usually the weakest point of any mod.

Nerak - I've watched this video before, just for entertainment, but I will have to watch again to see what could have happened.

You said the gasket looked good. I thought maybe the center post might need to be tightened. I saw in the video that once he put it in he did some tightening. Worth a shot at watching and seeing if that might be the case.

Yeah, I tried tightening. Didn't work and kind of marked up the center pin. Rob, I will be sending you an email in the near future for a rebuild kit. Does it include a new center post?
Yes it comes with a new center post gasket spring button feed tube bottle positive connection or firing pin everything needed to completely rebuild the unit
