Exxon Valdez - oil Separator? PICS ADDED!

[roadfrog]

Update;

So i added 5 litres of oil and fired it up. At first, nothing as far as leak goes, but then it started to drip after 5 mins. I went under the vehicle and tried to trace the leak. It appears to be coming down between the block and bell housing. There are three square holes on the housing and the drip is coming from them. However, it would also appear that some coolant is involved as well. I took pics and I just need to figure out how to add them here. FWIW - no warning lights, no check engine, etc. Runs like a top.....well.....other than the leak! I had a good look at the OSV/CCV hoses and they're dry and in good shape. from what I could see the OSV looks dry too. I have noticed lately having to add coolant at the rate of a cup or so per month.

Ideas??
