could very well be from the oil filter housing. I had a REALLY bad oil leak from there a while ago.

Go to realoem.com and navigate to the oil filter housing section of the parts catalog for your car. You can retrieve the part number from tehre and buy it online. If the usual suspects (pelican parts, bavauto, etc.) don't stock it, I am sure yu ca special order it, or even just get it from -- gulp -- the dealership.

Good luck.

If you ask me, it looks like something is missing in the area of those red arrows. A cap or plug. I am going to look at my car tomorrow & I will get back to you.....

I am not sure if you have fixed your oil leaks issue. For the past few months, I have had oil leaks issue. I have replaced what is obvious, but there are still oil leaks from different locations. I have replaced the complete valve cover gasket. Also, I have recently replace oil pan gasket. While I was working on the oil pan gasket, I saw there are some oil leaks from above. I think it is where your pictures shown. I too suspect that the oil filter housing gasket could be the issue. Did you fix or replace the gasket?

Thanks.

There are two o-rings sealing off the ports on the back of the oil filter housing. They get hard with age and can start a major oil leak quickly. I had the same oil leak a few weeks ago and just replaced mine... the ground beneath my car stays dry as a bone now.

I took some pictures. I'll try to take some time and get them off the camera and post them here.

You should be able to buy a box of different size 'o' rings from a good plumbing merchants, so far touch wood, when I have an 'o' ring fail theres always one that fits in the box full I have.

When you change the o-rings, I would recommend removing the entire oil filter housing for two reasons. One is because it is a lot easier to access the two ports with it off of the engine. The second reason is because then you can also replace the oil filter housing gasket which is probably also on it's way to becoming a problem.

Removing the housing is not too difficult and only involves renmoving the alternator, and dropping the power steering pump down out of the way. After that, there are only six bolts holding the filter housing to the block.



Here are some pictures of what is likely leaking on your car:






You can see the two ports on the back with the plugs in place. The upper port is what your red arrows are pointing to.






Once the retaining rings are removed, the plugs can be drawn out of the ports. Here's what it looks like with them removed:






Here is the underside of the housing that fits to the block. I also show the plugs, o-rings, retaining rings, and filter housing gasket laid out in front:





Here is a close-up of the plug, o-ring, and retaining ring:








Hope this helps out.

Well, even if he has already fixed his problem, hopefully these will help other people in the future. I too was trying to figure this issue out recently and couldn't find any good pics of what was wrong. When I fianlly got to the problem, I decided to take the pics in order to help others down the road.
