Somewhat unrelated to anything Ford . . . but I know this site has some mechanical geniuses . . . and I need help.
It's a Briggs motor. I use it with a water pump. Apparently the seal went out and there is water in the oil/crank case. The oil's a real pretty off-white!)
What can I put in there to clean all that out? I've heard diesel fuel works very well. Of coarse I wouldn't be starting it, just rotating the crank with starter rope and spark plug removed.
I think your best method would be to actually remove the crank case and clean it with maybe WD-40. If it's a water pump similiar to my powerwasher, the pump piston seals are what went out. It was about the same price to buy a new powerwasher as it was to buy either a pump or a pump rebuild kit.
Just drain it, refill and run it up to temp.
Air cooled engines get hot enough to evaporate the water and it will come out the breather as steam.
Putting something in like dish soap or Superclean that acts as a surfactant will just damage the internals.
Almost every IC engine has to deal with small amounts of moisture, and they do this by running hot enough to change it to vapor where it is cleared by the PCV.
BTW, WD-40 displaces water from surfaces.
It's just light oil and solvent, similar to a mix of kerosene and lighter fluid (with some perfume thrown in to cover the odor)
It has less surface tension than water and simply gets under it.
It does nothing to evaporate or absorb it.
