It was 50F and sunny, so two oil changes, car washes, cleaned the garage and yanked out the 3 port check valve for the windshield washers.
Popped off the red cap and lifted out the rubber diaphragm. Yep, just as someone posted a while ago. The fluid side of the rubber (appears to be silicone) had deposits of something that felt like bubble gum. It had picked up the dye from the fluid so it was blue. It was very well stuck to the rubber and did not want to come away. I could have tried goo gone, but did not. Did not try peanut oil either. I managed to pick most of it off, but a sticky residual remained. It appeared to be almost stronger than the rubber it self, and I was not wanting to tear the rubber. If it is silicone, I could see it tearing very easily. So I put it back in, with the not quite clean side now facing out and touching the backing piston with spring. It wanted to stick to the piston, so I used a trace of silicone grease to keep the two from getting stuck. So it now works much better than before. The valve would not work right when it was very cold, just when you would be needing proper washer action.
So the goo is probably something that the alcohol is leaching out of the hoses. Why it has an affinity for the silicone(?) rubber valve diaphragm is a mystery. The goo may also be what can plug the jets from time to time.
As I changed the oil on the 95SET, I noticed that the drain dimple area of the bell housing was bone try. After spending so much money to get the real seal replaced, it was a satifying sight to behold. This is my first drain of Mobil 1, after years of Castrol Synthetic. It also drained with a darkened hue, but was otherwise clear. On a paper towel, it appears to be soot free. Any solids will tend to show up when a small amount oil is soaked into a white paper towel. Perhaps I am so impressed with this because of my experiences draining the black death from the diesel's oil sump.
