If you pull the dipstick while the engine is running and the noise changes, its the valve cover which is also an integrated PCV air box.

any update?

most TQ have to be seated to the transmission input shaft first... if you didn't do this, it's probably your issue..

The other thing to think about is, you said the belt looked new. If this one suffered a failed pulley bearing, it may have cracked the timing cover. so look closely around the tensioner and pulleys.

G is right, you need to inspect through the wheel... there have been some timing cover leaks documented, and if you are getting that much oil out (with UV dye) after a short trip, this would be the area in your pics. Also, I recently saw a post about the oil cooler leaking on another member's v8 ove...

Sounds like they reused the bolts. A new bolt from volvo will fix your issues. The collar size was updated. Also, these bolts are torque to yield so they shouldn't be reused.

Yeah try that. Both of those other variants wouldn't give the same feel. The FWD isn't locked front to rear when moving so the binding wouldn't be as bad and the T6 was chain driven not gear driven in the angle gear so there would be more slack there.

What other ones for comparison? What type of surfaces? If it’s sand or gravel or wet, this would be normal with tires that do not have great traction. As the turning radius increases the inner and outer wheels spin at different speeds. Typically tires will hold traction and absorb this “pop” or skip...

There are many cases where new control arms contributed to a pull. Unfortunately, you cant tell just by looking at them. The thing to do is get a camera under there and record while braking to see what the play looks like.
