It's coming out somewhere - but I can't figure out where!! About a week ago I, um, left the oil fill cap off on my '85 W123 300TD. So I stopped by a coin-fed pressure wash. I'm pretty sure the suspension didn't leak before that. Now the leak will drain the tank. It gets all over the front of the engine, on top of the power steering pump, the underside of the hood, and then it oozes out between the hood and fender.
It's possible the fan and ram air are responsible for how it's spreading. What is frustrating is I can't make it leak while I can look!! I've tried at idle, against the governor, jumping on the back bumper and a quick run to the hood. And yet 15 miles later there's (expensive) oil all over the place. The pump draw hose looked tired, and so I replaced it with a fresh, but incorrect hose. No change. I can't see any evidence it's the high pressure line. It doesn't seem to leak when the engine isn't running. Any ideas? Am I correct that the high pressure line won't have very high pressure unless the control valve at the axle asks for lift? Maybe I need to contrive a lift situation while in the driveway - more than just jumping on the bumper... -- Philip, not a hydraulics engineer. _______________________________________ 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://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
