About a week ago I pulled and resealed my SLS valve, and since my 300TD's rear end sags after a day or so of sitting, and then comes back to regular height when I start up the car. It doesn't seem to be leaking fluid.

I resealed the valve using the o-ring kit I purchased from a member on the forum. I'm certainly not blaming the member for the issues, but I'm curious if anyone has had this issue, and what the best remedy is?

I followed the reseal instructions, so I'm 99% certain I put everything in correctly. The valve was working ok before I pulled it to reseal (DOH!), but I had just previously pulled and rebuilt the pump, and installed a new HP hose, so I thought I should do the valve while I was rehabilitating the rest of the system.

Would the MB reseal kit with the extra valve pieces possibly fix this issue?

Any thoughts would be much appreciated.
