While replacing engine oil yesterday, noticed oil stains on the underbody shield.
When looking up, I saw oil dripping from the AC compressor and a hose connecting to the radiator.
Seems like engine oil.
The AC compressor was replaced in 2018 at MB dealer,
just few months ago I replaced oil filter housing seal, oil cooler seal, steering fluid reservoir & o ring.
The only possibility I can think of is the two cam position sensor seals
any other possibilities? Thanks in advance.
Yes after replacing all those gaskets few months ago, I actually drove it without the underbody plastic shield and did not see any stains on ground for few weeks. Then I put the shield back.
btw this is the first time I drain the engine oil from the drain plug. pretty easy.
maybe not as convenient as the dip stick tube method since there is no need to jack up or removing the shield.

If you didn’t know, the crush washer on the drain plug is replaced, never reused.
Germans use crush washers everywhere it seems, and they are somewhat magical items that perform two functions at once … fluid seal and lock washer. They don’t do either a second time. The specified tightening torque is the force required to crush them.

yes I even used a new drain plug in addition to the new copper washer.
