Default Help me diagnose my oil leak!

So over the past few weeks ive noticed on my exhaust side a few oil leaks. The most obvious are the valve cover gaskets which im going to replace in the next few weeks. There is one more right below the distributer and above the water pump that is concerning me. What gasket/seal in in that vacinity? Other than the distributer (which i have already replaced)?

Im installing my kit next weekend but as it sits its na. I really want to figure this out before my install so i dont lose all of my oil while my turbo is installed. It leaks so bad that after i fill it up, a couple of weeks later i will only have about a 5th left. That 5th wont leak out for some reason either. Would the valve cover gasket leak all the way down there?!?

you should just pick up a gasket kit and change all your gasket if you are going turbo...

best thing to do also would to clean all the off everything. and then when the leak starts you will be able to narrow down where it is since everything is clean.

It defenitly the Dist O ring and some is the Valve covers. I just changed mine it was the same thing. The O ring was hard as a rockand just broke in my hands. My valve covers were leaking so bad when bought the car that lexus thought it was the rear main seal. Make sure you clean everything after your done so that you know if it leaking again.
