Check engine/VSC light came on. Dealer says " Bank 1 exhaust oil control valve" - $650 repair. My 2004 RX 330 (305,000 miles) never had this problem. Is there another way? Or should I bite the bullet.

Bought this 2010 RX 350 one month ago from the dealer, who included a 3 month powertrain warranty - is this part of the powertrain?

Any thoughts would be appreciated!

Engine is the power and train includes transmission/drive to the wheels. I would suggest read the warranty carefully to see what is covered and what is not. Read the fine print for exclusions.

Most of the 'weasel-words' that I've seen in warranty plans specifically exclude any parts that are not "internally-lubricated" -- and an exhaust oil-control valve (whatever in the heck that is -- is that near the muffler-bearing or rumpets?) sounds like it's "internally-lubricated" by definition.

Good luck! Keep us posted.

I would argue it is part of the powertrain and call Lexus corporate to complain before paying, maybe they will cover it for goodwill. I would also ask a local independent shop if they think it is part of the powertrain. I think this went on my old ES350 but it was under factory warranty at the time. It has almost the same engine.

Looking at this link to a Sienna (same engine basically) the valve is certainly internally lubricated. http://www.tsienna.net/r_amshaft_tim...embly-592.html Look at the 3rd drawing down from the top.

I would opt for at least unplugging it and measuring the resistance between the two contacts.
If open, replace. You could swap with bank 2 and verify problem moves with valve.
While out verify it shuttles with 12v applied. How often you change the oil?

it should be included in the power train as it is vital to the Variable Valve Timing function on modern cars.
it is however super disturbing that it went south this early. On my Gen 1 RX, my first bank oil control valve died at 160K miles. The second bank valve died around 230K miles......
