Before re-installing water pump I took a look at the "cross over passage" across the engine from the water pump leaking seal cavity to the other side of the engine to the exit hole.You can see light all the way across and even poke a wire all the way through.
Anyway,after coming across a secret ducati service document to their technicians basically saying that the water pump is designed to leak and not to replace any parts because its supposed to leak I did the Super Leggera band aid on my bike which is a fitting on the exit weep hole to a hose and then to the ground so the leaking coolant does not stain the engine.While the bike was apart I removed the entire exhaust flapper cables/actuator assembly ect as well as the entire carbon gas fume thing,including right up to the two fittings on the intakes.Removed both of those hose fittings and replaced with copper washer,bolt and red loctite.I re-used one of these M6 thread by barb hose fittings as the fitting to install on the weep hole.Drilled and tapped the exit hole,installed fitting with copper washer and loctite,attached high temp,transparent silicon tubing and ran hose down to a high temp ,transparent plastic bottle installed in the space near where the exhaust flapper motor used to be.
Now,in the future,if there is any coolant leaking out of that hole it will be stored in a container that I can view the amount of lost coolant in.
There is a way when drilling the M5 hole and threading the M6 tap to prevent any cutting fluid and shavings from entering the cross over passage.Just ask me. I`m still hoping someone has an answer on my first question regarding the 5-7 bolt holes on the water pump.
