Disa @ 190k miles

Took it out today and it looks okay. Took it apart as far as the rebuild kit suggests, and put it back together. Only bad thing is it kind of fails the vacuum test. Instead of holding the flap still it slowly returns to closed position. Does that seem like the internal seals are failing ?

That's what mine was doing. Everything was nice and clean and actually perfect for having 270k+ miles on it, but it wasn't holding vacuum. It would only hold vacuum if I first plugged the hole, twist the flap and then let go. Diaphragm is probably gone

yeh that diaphram. I tried to open the plastic cover on it that seems to be held only by two clips, but it wouldn't budge and i didn't want to snap the clips. Car runs fine.
