This sounds exactly like a loose heat shield on a muffler, catalytic converter or some times a heat shield on an exhaust manifold.
Often it is just a matter of resecuring the heat shield with a replacement screw, muffler clamp or hose clamp. Go for a free muffler inspection somewhere and ask them to check for a loose heat shield.
Naturally the heat shiled can also be replaced if it is in really bad condition.

Does this model exist? I am interested in an AWD Sport, and can not find one in stock anywhere (Florida).

We've had a few people discussing the Sport in the Ride of Sport vs Limited (2008) topic. Have a look!

You might want to hold off until the new model when the HL will undoubtedly get the new, more functional. F/awd system already in the new Venza, RX350, and Sienna.

#10959 of 10987 Airflow direction thru cabin air filter?
Apr 16, 2010 (11:56 am)
I have a 2004 Highlander. I have always changed the cabin air filter myself and I have always thought the airflow direction was top to bottom. Now I'm not sure. The fan is underneath the filter which makes me think the airflow is bottom to top (unless the fan is sucking air thru it.) The old one is dirty on both sides but dirtier on the bottom side. The manual has an arrow pointing up but I think that refers to the orientation of the tray.
Anyone know for sure which direction the air flows thru the filter?

As mentioned in a reply to your other post, the air goes from top to bottom. It enters through a large oval port under the cowling. You can see it with the fan and filter removed by looking up with a mirror.
I live in the country and had a terrible time with rodents entering through that port then chewing and nesting on the cabin filter. I had to install a wire mesh over the port, which wasn't easy.

2002 Toyota Highlander has had high oil consumption for many years ONLY AT HIGHWAY speeds. I would go months with city driving and not use a drop of oil and then go on a road trip and use 1 quart per 150 miles. Dealer confirmed no engine sludge and replaced PVC valve, but this did not help.
New valve covers were put on the engine (~$750 as I recall) and this has fixed the problem.
