oil was supposed to pour out everywhere. the oil in the housing is to help dissipate heat generated from suspension travel. all of that crap you mentioned won't help a thing unless the part changed is what was wrong. what you have described doesn't say shit about what the car is doing under 'poor handling' mode. in my guesstimation, the sensa-trac's may not be damping the springs enough. anytime you lower a car, you generally stay with low-er pressure gas. even with a progressive rate spring.
