My 1994 SL600 with 40,000 miles developed a suspension fluid leak near the front leveling valve. The leak was on a block attached to a manafold where all of the pressure lines attach. I replaced the O rings and the leaking stoped but the front shocks are pumped up thght and the rear are down low.
Any suggestions on how to resolve??

 

Where are the oil rings,mine has a minor leak too.

 

My leak was in a check valve that is attached to the fluid distrubition valve behind the right front wheel. I had to make a spanner wrench to remove the bolt and re o ring it. Then I found out the special procedure for bleeding the system.
