The total system capacity is only a couple liters, so it can sneak into the crankcase and may not be notice. Also, because it's much thinner, it will thin the crankcase oil and probably cause an increase in oil being burned. A slow leak will be especially sneaky. > I was thinking that it might be leaking while the engine is > running, or maybe I hadn't added enough fluid to begin with. > To hopefully diagnose this problem, would it be OK to add SLS > fluid to the refill canister with the engine running, while > checking for leaks? Absolutely. Also note that the returning fluid. Unless the system is pressurizing the shock/accumulators, there will be fluid returning from the line connected to the tank cap where it runs through the filter on it's way into the tank. I had a hose develop a pin-hole leak in the high-pressure hose crossing the engine. This made a mess, though, so I don't think it's your problem. -- Philip _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
