Update: There is apparently a TSB by Toyota in Aug 2011 about a defective piston assembly which causes excessive oil consumption for 07-09 tC's and affected xB2 with the same 2AZ-FE engine as us.
55k Miles on this 2008 Scion tC. Regular oil change intervals and never let the oil go low. Never had any issues before but on this last interval I noticed this unnerving tapping or knocking noise which seems to be coming from the upper end of the engine.

2008 Scion XB Oil Consumption
Here is my 2008 Scion XB currently with 58,151 miles on the odometer. Get
my oil changed at the local toyota dealership regularly. Was driving
yesterday and my oil light came on. Checked the oil and as you can see, the
dip stick is bone dry. My oil change was due at 58,298, so i wasnt even due
for an oil change just yet. There is a service bulletin that came out in
2011 for this particular engine. The warranty is 5year/60k miles.

Toyota 3.5 engine tick tap
2008 Toyota Sienna
The engine makes a nasty tick and the dealer refuses to fix it citing that
Toyota has written a loophole into the technical service bulletin that you
must have a check engine light for them to fix this problem.
Well, i prefer to not have total failure on the side of the road before it
I've had several dealerships look at the problem, acknowledge the issue and
end up talking their way out of fixing it.
Toyota HQ is pretty much useless and they just work with the dealerships to
not fix the issue.
I'll take the video down when Toyota fixes my engine tapping.
2011 Toyota 3.5L V6 engine tapping noise
The engine makes a tapping/ticking metal on metal noise at idle after it
has reached operating temperature.
I had first noticed this the night we had brought it home from the dealer
while pulling into the garage. The car at this point only had approx 40
miles on it.
I did not think this was normal so I took it back to the dealer and the
mechanic said there was nothing wrong with it.
I'm not a Toyota engine expert but when I hear a metal on metal sound
coming from an engine it cannot be a good thing. Sounds to me like piston
slap, bad lifter, or something is wrong with the VVTi camshaft assembly?
