Coming back with an old topic here.  I checked the archives and didn't find
any mods for the breather tower.  Still getting oil in the intake boot.  Is
there supposed to be something in the tower on a 1.9 to keep out the oil and
only pass the vapor?  The engine doesn't get to hot but I do travel about
750 miles a week at speeds that vary from 55mph to upwards of 80mph and also
climb a 6 degree grade every day.  Last year I averaged 21.6mpg so I don't
think there is any kind of a power problem in that the mileage is good and I
can accelerate up the grade (so long as there is no head wind).
