In a word...YES. I still get a little noise on startup. But it's VERY faint
and dies away almost immediately. However, I predict that "draining the pump"
may become a maintenance item. ;-) It's easy to do...so I could think of

It's gotten into the 30s already here...so it's been tested in cold-ish
conditions with same results. Seems to work OK.

Please let me/us know.

Taking the pump off, apart, clean, reassemble, reattach took less than 1/2hr.
Not including a run to the hardware store for some cap screws. Next time
it'll be 20 mins. As opposed to $$$ for a new pump, it seems to be a good
Taking the pump apart is not big deal. You just have to be careful not to
break the o-ring gasket and remember where all the parts go. Go slow and
think. BTW. this thing hemmorages oil everywhere when removed from the car.
It's a very steady trickle/fast drip when the pump is turned in two certain
directions...either with the shaft pointing down or the hose nipple pointing
down. Anywhere there's a hole, the oil will come out. In fact, it might do
the trick to just take it off and drain it. Maybe taking it apart isn't
