Hi . Does anybody have any idea if the resovoir drops pressure through the night when car self levels? Mines is going from 190 psi to 160 psi over 8 hours... I’m trying to solve an issue as my front end is dropping a bit.. I have already replaced front struts and was wondering if a sticky front cross link valve could allow air to release ? Thanks

Air can leak to atmosphere from a valve block. Mine's front has been dropping after several hours for a long time and I'll overhaul the valve block eventually.
