oil collecting on ac hose, how to deform your hood - PeachParts Mercedes-Benz Forum

Doing the old visual check of the 240D today and noticed oil on the lower ac hose. Sits about 4 inches in front of the oil pan where there is the usual seepage issue. No other source of oil identified. Oil lines to cooler look ok. Could vibration when the car is running but not moving throw oil onto this hose?

Also, had a nice experience bending my hood when the wind caught it while in the upright position. Tried to pull it shut not noticing that the lever had moved forward into the locked position. Gave it a good pull and watched the hinge move inward on the left. Closed the hood and sure enough, the near corner on that side is higher and farther away from the firewall body panel. Cursed my existence for awhile. Raised the hood and tried to move the hinge complex outward without much success. Ultimately, I think I improved it by opening the hood to the first position and pushing upward GENTLY but repeatedly. Not perfect but better. I'm not sure it was perfect before. The gaps on the side are symmetrical and the leading edge in front is the same. Sometimes we are our on worst enemy...

Assuming that the oil is engine oil, a leaking front crankshaft seal is a likely cause. The balancer slings the oil around as it rotates. Then the oil runs down the hose when the car sits idle.

and the fan blows it pretty well too.

sorry about the hood. getting out of my truck for a benevolant club meeting i carefully opened the door to the middle stop and let go of it to get my hat. a quick gust of wind came up and threw it savagely against the innocent '06 honda back right fender next to me. (wednesday morning). so i left the business card in the wiper. turns out to be a fellow breakfast optomist. and the low estimate is like 375. trying to decide whether to anti up or turn it in on myinsurance.

these things happen. just to keep life interesting.

Check your power steering low pressure hose. PS fluid will sweat through the pores of an old hose. It will drip off the oil cooler and air conditioner hoses and make you think those are the source of the leak. Sure fooled me.
