The oil level was actually really low, barely registering on the dipstick, as it was just after the oil change and I tend to fill one quart low until I can check it when the engine is warm.

I removed the muffler and cat this weekend. The old rusty bolts were not fun, I had to use the dremel to cut 2 of them.

The hot side on the 3LDZ was pretty black from carbon buildup, but not really oily as I would have expected if the turbo was leaking oil.
I haven't looked at the cold side yet but the charge pipe was pretty dry.

Should I expect to see oil if the turbo was leaking on the hot side ? Or would it be blown by the exhaust gases and burn anyway ?

The 6-yr old spark plugs were all pretty black, more than normal, the greasy kind of black, all of them, so maybe the turbo was also leaking a bit on the cold side ?

The turbo is still in the car with the 2 oil lines connected. Do I have to remove the drip tank (stock one) to get it out ?

Another question regarding the turbo oil pump. Do these sometimes fail ? Is it possible that the oil pressure was building up in the turbo causing it to leak after a couple minutes ?
The turbo oil pumps or scavenge pumps are pretty strong. I would change the seals because if they leak inside (shaft seal) then they might not work or not enough and might cause your issue.
