guys, there is a passageway, on the top of the engine near the turbo mount, that drains out near the starter mount first picture in post #15 above. My dealer told me about it a long time ago but I've not been able to confirm.
I think the passageway is so that if an oil leak occurs on the top of the engine, the oil has a way to escape without causing a fire.

What they told me is that any oil leak starting on the top end, even the leak near the air intake tube that destroys the swirl motor, drains down to a small exit near the starter mount. With a 4x4 its (near) impossible to see the drain hole - I've been trying to get confirmation of the exact location of the drain entrance and exact location of drain exit from anyone that rebuilds these engines. I actually think there is a way for any oil that escapes the crankcase breather valve to also drain out at the bottom, but again, its only my suspicion. Frustrating that its so hard to find someone that answer simple questions on this engine.

When the oil exits near the starter, it continues its journey to the lowest point on the back of the engine, this is the bell housing to the transmission and this why the leak is commonly blamed either on rear main seal or the oil pan gasket.

This is kind of what i was looking for, I have noticed a few drips on my driveway every once and a while but not to often. And I was wondering if it could be from the intake seal or something like that. I havent had time to take a good look underneath but I just dont know where to start ha. Hoping its just a drain line from something that isnt a problem.
