K1100 water pump help needed

[manuel81a]

Dear K11 fans, enthusiasts and owners around the world.
I am writing you from portugal and I have some doubts to adress to this comunity of experts.
Early this year I have bought a beautiful Grey K1100 RS from 96'.
It had only 46k Km on it and I suspect that the bike has been stoped for long.
I have started to drive it on a daily basis and I've started to notice some oil leaks and other minor issues that were requesting a major overall maintenance.
Being a mechanics enthusiast I've placed my order to motobins of many parts and seals.
I decided to do also the maintenance to the oil/water pump, replacing the sealants, which after damaging water seal on the first try, I believe it went well on the second one.
When doing the maintenance, I have cleaned everything the best I could in the inside and the outside.

I have seen this hole on the pump which is a channel that leads from the center of the shaft to the dripping hole seen on the picture bellow

When the pump was disassembled without the shaft and the seals, I have inserted a thin screw driver on the hole/channel pointed on the first picture intending to clean it and in fact it seemed to be obstructed with something that looked like dirt.
Now, having the pump reassembled with new seals, it drains all the water from the refrigeration circuit from the dripping hole! :?
I have then disassembled it twice after that and I realised that everything looked fine, no water contamination on oil or the oposite.
I have tried the bike on both times and disassembled the pump after trying it and everything looked fine with the sealants with no signs of water on oil or oil on water, but it drains all the water that I put on the refrigeration circuit 
Have I done something wrong when I inserted that thin screw driver on that channel thinking that I was removing dirt but maybe it was not dirt but maybe something else to prevent the water from running out from the dripping hole?
Now I have placed some bits of silicon inside of that channel to prevent the water to come out and everything seems fine.

Please, I look forward to all your comments.

Thanks

The weep hole on the bottom of the engine, which you circled in purple, can leak oil or coolant (or both) from the water/oil pump.

Did you use a new shaft with the new water pump seal? From my own experience and gathered knowledge here, if it has pits (due to being exposed to atmospheric air), it will likely tear up the new water pump seal when you go to pull the shaft through the seal. You either have to use a new shaft or attempt to fill in the pits and sand it. I don't know if JB Weld is available in your country but it's a "cold weld" epoxy which can be sanded and from what I gather is alright to use.

Did you use instructions like this?

It's quite possible to damage the new seal when installing

The weep hole you've circled lies between the oil seal and the water seal.  Normally, no weepage comes out of that hole because the region between the seals is dry.  if either seal fails, the corresponding liquid will weep out.  If water came out, then the water seal is compromised; it needs to be replaced.  That hole needs to be open, not sealed up, otherwise the liquid has nowhere to go and will find the path of least resistance, meaning probably coolant finds its way into the oil.
