Another day, still "leaking", though the cap swap may have slowed it down a bit-maybe, seems like only half the fluid was gone with same number of miles, but I didn't use a proper scientific protocol, don't know exactly how many miles was emptying it, nor exactly how many miles I drove this last time, so, maybe not. I have put in a total of about 3 quarts +/-. Do you know if the unit generates enough pressure to push fluid out the bottom of the cap?
