top rear oil leak

I have been trying for 3 months to get rid of the oil dripping on my driveway. I know it is coming from the top rear of the motor and have replaced the turbo and ped orings with no luck of it stopping. I can wipe off oil from starter and trans and go for a drive and be there again ready to drip. It may drip 1 maybe 2 drops a night so I know it is a very small leak where ever it is. Oh and the ebv rod has been plugged too. I know I have some blow by and getting some from the boots but I just don't think that is where I am having this problem. I plan on getting a catchcan for it one of these days. I was just curious if anyone knows of any other o rings or anthing where oil can leak to cause this. Not really a big problem but makes the driveway look like crap.

I tell you, it would not be hard to ruin a turbo O-ring while trying to stick that thing in there. I just installed mine cause of the up pipe exhaust leaks. Its a pain, and tight in there.

You positive it's coming from the rear? Is there oil in the front part of the valley? If there is, it is the HPOP o-rings most likely.
