Certainly not trying to hijack the thread...

But my scissor lift has a foaming fluids problem. When I lower the lift it makes, kind of, an aerating noise - sort of like a milk foamer on a coffee machine, when I lower the lift. Foamed up oil comes out of the filler hole. It's not over filled because if it's less it won't lift the car all the way up. I changed the oil to the correct stuff and it still does it.

Any ideas?
