It has been hell just to get the oil pan off since it is AWD. Anyway, I finally got it off. See pictures. The last owner was driving on a highway, got low oil pressure light and engine stopped.
I found the oil suction almost completely plugged with plastic bits and sludge!
On the good side the oil pump chain appears fine and timing chain is not broken.
It remains to be seen if the chain skipped due to plastic parts running between the sprockets and chain. If that happened, then the exhaust valves would almost certainly be all bent. Maybe intakes would be fine due to valvetronic only opening them a small amount? Pulling the valve cover off tonight.
