OM642 oil leak, can't find the source...

I've got an oil leak on my ML320 CDI that I can't track down, it's running down the AC compressor and dropping onto the radiator support cross member. There were several leaks, one from the oil cooler and the power steering pump, I've fixed those and just have this last one to clear up. Anyone have any idea where this could be coming from? A few pics are attached, this is all the view I have of it. I'm not even sure what's behind there that could be leaking and I don't want to pull the compressor unless I have to in order to repair this. I have a refrigerant recovery machine and all, it's just a pain to do it all and the AC is working well. I hate messing with stuff that's working...

Hello. There are common oil leaks on the OM642 platform. One of those leaks is the oil filter housing gasket. It's normal for it to fail and I'd bet good money that's where your leak is coming from.

This is the gasket:

Oil filter housing:

If you decide to buy the oil filter housing, then it will come with the new gasket installed already, fyi. GL.
Thanks, I'll investigate that. The location it's showing up at would correspond with the filter housing so I suspect you're right. I think I'll do the $5 gasket instead of the $145 housing... :)
