I'm having some problems with my sls and was hoping someone might have some advise. Here's the deal: i drove her for about a year with no problems at all, though she would drop down after sitting over night (internal leak right?), anyhow, several months ago the sls began working sporatically. Sometimes she would rise up, other times not, occasionaly after driving on the highway for a little while she would pop up. More recently she stoped working all together. I finally got under the car, moved the valve adjustment bar a little a sprayed it down with a lot of pb blaster (lots of rust under there). Next time i started it up she lifted right up and stayed that way for a day or so. She finally settled back down and won't lift back up, once again though, after highway driving she does sometimes seem to pop up, sometimes. I know my pump works, i also know i have a small leak on either my driverside shock or accumulater. I'm thinking i need a valve rebuild kit. Sound right, maybe some advise. Thanks.
