My dart leaks power steering fluid... There's no continuous leak... it just leaks out when it feels like it. I can't tell if it's when I turn the wheel or if it's when the car's not level or when I hit bumps or whatever... it just leaks when it leaks. Actually, it's more like spews. One thing I think might be the cause is that the front left shock/strut is fairly bad and sags a little... but I can't figure out why it only 'leaks' sometimes, and others it won't at all. Should the cap of the power steering be air-tight or just loosely on there? It says "Vented" so I figure it shouldn't be, yet that's where I think all the fluid is coming out of.

Thanks in advance for your help.

The cap should be snug on the reservoir. The vent is that small point in the center of the cap.... has a spring on the underside that vents pressure if it happens to build up in the reservoir.

I would clean up the pump with some degreaser or whatever your favorite method is, and next time it leaks look carefully to see where the leak is coming from. Probably a seal is starting to deteriorate?

Try some power stearing stop leak. This swells up the rubber seals so they, well, seal better This worked for me. I hear adding a bit of brake fluid in to the ps reservoir does the same thing, but the stop leak fluid is only a couple of bucks at the local auto store.
