patient for a bit and see what happens.

I think Stan is on to something here. During my recent 912 course I mentioned that I was having some leakage in my 912UL below the water pump. In my case it doesn't appear to be coming from the weep hole. The instructor mentioned that it might be coming from the stainless steel bolt that uses a copper washer for a seal. This is used to drain the pump. I ordered a new copper washer and maybe this was the problem. Will find out when I fill the system and run the engine.
The instructor did mention that Rotax does allow for some leakage from the weep hole. Not much grant you but I think it bares watching to see if it will resolve itself. I believe it mentions in their instructions about counting so many drops a minute, hour,etc. I saw it somewhere but can't put my hands on it.
