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! Confused
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 Crying or Very sad
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 telltale hole should be open.....so you see when the oil or water seal starts to leak.
When you close this hole you're also in the risk of mixing oil and water as the leak have nowhere to escape.

Thank you for your reply Inge K!
I understand that the hole or the channel inside the water pump should be open but the thing is that, before I think that the channel inside the pump that leads to the dripping hole was obstructed with something that looked like dirt.
Now, because I opened it, it doesn't retain the water from the coolant system.
It drains all the liquid from there.
Though there is no signs of water contamination from oil or the opposite water on oil.
The pump seems to run fine.
Need help in here.
