I am assuming that this is tied into Toyota's variable valve timing. Just speculation on my part.
But this just looks like the same junk engineering that has brought the domestics to the doorstep of bankruptcy.
I'm an oldtimer, owned many cars and trucks, a semi even. And never have I
had a camshaft fail. Never had an engine fail, except for the semi and those were normal rebuilds with many miles. Switchgear, sensors maybe, but nothing internal.
I gave up on the domestics because of half engineered and unreliable products, And no support whatsoever from the corporation after you bought the product. At this time, I would say the Toyota Scion is no better in those regards than the domestics were when I quit buying their products. This is an internal engine part that failed, not a sensor or some such.
What happened to the Toyota's like the late eighties model my daughter owned that she ran for over twelve or so years with just basic maintenance? Now I see reviews where Ford is now matching Toyota for quality. I hope they do better that that.
problems, 1st thing you do is check the fuel for the % of Ethanol. In this area Texas
Ethanol has been found in only 1 case too be 100%. It has been discovered in other cases from 18% to 27%. No matter what Obamas EPA tells us, our cars were not built to run on more than 10% Ethanol. Check The Ethanol 1st---Before you spend any other money. David
But in your case, please check your oil first! But it could be a simple heat shield or one of the splash shields could be falling off, lord knows how many times those shields have falling off on us. Look under the car see inf there is a shield hanging. I'm a mechanic by trade & Own and opperate my own company. Check out MatthewsRoadService.com
Keep in touch with us, Oh ya one other thing if you don't know your car is consumming oil , when you have your oil changed ask them to measure the oil that comes out of the engine. The XB takes 4 quarts of oil, 4 quarts go in 4 should come out in a normal running engine. But when the dealer did the last oil change, 1.25 quarts came out, and I put 2 quarts in it a month prior to that change.
Do you check your oil on a regular basis? These cars consume oil on a regular basis, look at your service manual, under oil consumption. I got pretty pissed off when the dealer told me that. So I am collection names, addresses and phone numbers to produce to a lawer to wack toyota with a reality wack! Let me know, Matt
Keep in touch with me, I'll add your complaint to the rest of them. Also check your service manual under engine oil consumption! See what it says, Unfortunatly its not good and its not right. Write your congressman office and complain to them also write a letter to your Attorney Generals office in your state. My letter just went out about two weeks ago. They will responed!
Contact your local States congressman, all of them! Also write your complaint to your states Attorney General, Lets get the word out about these engine issues, I'll never buy another Toyota or Scion for that matter!
I'm worried. Any ideas? I'm out of dough. Just had the windshield replaced for $199 cash and the brakes done, badly I might add, at a cheapo shop I shouldnt have used. So I'm out of cash, dead broke and I don't want a dead Scion that's for sure, because I need it to live (get to store, do my job, etc).
Thoughts on the matter, mechanics out there? I read on the list somewhere, ethanol might be to blame. Well, when they upped the percentage sure did lower my mileage by about two to three mpg. Darn it. But I never have had starting problems ever before. I had it to a shop month and a half ago, to change tran fluid, check everything out. He told me the switch is stuck in the window, the open close the window switch, and he was supposed to order the replacement part but hasn't. Maybe it's draining the battery. But it sounded more like the engine was coughing, not getting enough air or gas, straining, made some wierd little cut short sucking sounds, too. Didn't like hearing that. If I'm driving and hear bad car engine sounds, i turn up the radio, but I hadn't gotten out of the garage yet.
Basically, the timing is variable, and changes - its dependent on the car's oil pressure. Its ingenious and sounds complicated but works relatively simply. The oil pressure switch communicates the pressure to the variable timing gear (your failed part, in this case) and that gear adjusts the timing for the best performance and/or fuel economy. Its amazing!
I bought a used 06 scion xb with 40 k miles and had this VVT-i gear fail on me as well. It is a common problem on SOME early - mid 2000 model toyota 4cylinders, and normally fails when the vehicle is within its powertrain warranty coverage. The problem lies when someone ignores their check engine light, or takes it to an inferior mechanic who replaces the wrong parts (like ignition coils? wtf? never had one of those fail on these cars..) and the problem continues, unheeded until it is past warranty coverage. Mine was covered free of charge, on a saturday, by my local 'stealership'.
Even if you are past your warranty coverage, it is NOT a HUGE job. This car is pretty easy to work on. The VVT-i gear is just one of the timing chain gears. The side cover comes off, you change the gear, (i think it may be on the end of the camshaft?) maintain correct timing, put it back together. voila. Book labor time is 4.8 hours. I have seen much worse cars...
Every car has a common problem, a slight weakness from factory, and this is the only one I have found on this car so far, It may seem dramatic to some - but trust me, i have seen FAR, FAR worse... I love this car. It is an economy car, sure, but i love, love, LOVE it.. and it has served me very well. It isn't for everyone, though!
(...I have also personally seen some valve timing issues on the early model honda elements as well...)
Another note, since I have seen a few other people mentioning coils.. DO YOUR SCHEDULED MAINTENANCE!!!!!!!!! This car needs the spark plugs changed every 30k miles. It is factory equipped with copper resistor plugs and they do not last very long. Do not, by any means, EVER, replace the plugs with platinum or iridium instead. The ignition system is designed to run on a resistor. Your car will run rougher and get less gas mileage with a different composition plug. Also, the stock plug is an NGK v-power copper. I highly recommend!!!

Hopefully they do the right thing and include Scions which use the same 4cyl 2AZ-FE motor.
Here's a summary of the TSB (notice they loosened their acceptable standard for oil usage from 1qt/600miles to 1qt/1200miles; still a lot IMO, but hopefully enough to satisfy the owners of cars with excessive oil consumption):
T-SB-0094-11 on Nov 11th, 2011:
--------------------------------------------------------------------------
"Some 2006 – 2011 model year vehicles equipped with the 2AZ-FE engine may exhibit engine oil consumption. The piston assembly has been changed to minimize oil consumption. Use the following repair procedure to address this condition."
YEAR(S) MODEL(S) ADDITIONAL INFORMATION
2007 – 2011 Camry HV, Engine(s): 2AZ, VDS(s): BB3EK, BB46K
2007 – 2009 Camry, Engine(s): 2AZ, VDS(s): BE46K
2009 Corolla, Engine(s): 2AZ, VDS(s): BE40E
2009 Matrix, Engine(s): 2AZ, VDS(s): GE40E, KE40E, LE40E
2006 – 2008 RAV4, Engine(s): 2AZ, VDS(s): BD31V, BD32V, BD33V, BD34V, BD35V, ZD31V, ZD32V, ZD33V, ZD34V, ZD35V
2007 – 2008 Solara, Engine(s): 2AZ, VDS(s): CE30P
Inspection Procedure
NOTE
In some cases, a P030# (cylinder # misfire detected) DTC may also be set as a result of oil consumption.
Perform an oil consumption test to determine the consumption rate.
1. Confirm the engine oil level is full.
2. Mark the oil dipstick to indicate the current level.
3. Replace the oil dipstick.
4. Mark the oil dipstick, oil drain plug, and oil fill cap to prevent/indicate tampering during the test.
HINT
Use tape, sealer, cable ties, or equivalent to mark the oil dipstick, oil drain plug, and oil fill cap.
5. Advise the customer to drive the vehicle normally for 1,200 miles and return for inspection.
6. Determine the quantity of oil that was consumed in 1,200 miles.
Was the oil level more than 1 quart low after 1,200 miles of normal driving?
YES — Go to the Repair Procedure.
NO — This TSB does NOT apply. Warranty guideline for acceptable oil consumption is 1 quart per 1,200 miles of operation. No warranty claim should be filed.
My 2008 xB uses about 1 qt. every 2500 miles and it has been getting worse! If Toyota won't fix this problem owners of the cars affected will take a large hit when trying to sell.
Stay away from the cars listed in the above TSB and all Scion xb's second generation 2.4 engine.
Still haven't received my RECALL letter about the bad ignition coils!
If you Google "Toyota 2az oil consumption" you'll find several forums (some with 100's of posts) that discuss this issue. Unfortunately, from what I've gleaned from reading through all the posts, Toyota/Scion is sticking to their standard of 1quart burned/1200 miles within their 5yr/60k mile warranty period. Very few will hit this rate below 60k; it seems as though a majority of the higher oil burning engines are over 80k. Maybe if Toyota/Scion gets more pressure it will extend the coverage of this TSB to 7yr/100k (this sounds more fair to me).
I have about 8 months left until my warranty expires, so I'll be keeping a close eye on my dipstick. My current rate of oil consumption is 1qt/2000mi.
Hope this helps someone out there. Post any add'l info if found. Thanks

my xb vin is below number listed, Srv Mgr said extended warr will cover if I've kept up service.
I take my car in for oil changes regularly, but admittedly I often go beyond 3000, to 4000, sometimes even 5, or 6000; but the treatment I've given re mileage btwn oil changes, and general attention to the slightest detail of the cars performance, has been the most dillagent of any of the many cars I've owned. But, if anyone at the dealer had said one word about it consuming oil, I would have checked the oil all the time, or often and avoided this (engine is toast! and I LOVE my car!) problem. They stress--in fact my best friend is the service mangr--my tardiness in mileage between oil changes, but never told me that I was ever low when I brought it in--I have checked the oil only once or twice in its 113,000 miles! This is NOT because i am an idiot that has no idea of how cars work. On the contrary--as I have never had a new car, I thought that if I kept bringing it in as close to the oil change times as I could, which again, is by far the most oil changes of any car I've owned, the dealer would tell me/advise me if anything needed watching with my car--OR AT LEAST TELL ME MY OIL IS LOW WHEN I BRING IT IN CONSISTENTLY AND THIS CAR CONSUMES OIL ANYWAY!!
Sorry, anyway, that is my long winded way of signing on with you in this. This car was is the most important purchase I ever had, and I am devastated to say the least. PLEASE HELP!! And again, THANK YOU!! Tony Beers, Wash DC
If you plan to continue to own an automobile you will have to educate yourself.
Excuses only work for Politicians.
I posted about week ago re my 08 Scion XB (112,500 miles) and wish to pursue this issue for SO MANY reasons, the most important of which is the fact that I can't -- financially -- go out and replace this car!!! I know that I will have to try and borrow some money to get a car while fighting this, but fight I will!!! PLEASE, if anyone can assist in a mutual effort to out Toyota and get compensated for this ridiculous oil issue, please weigh in!! Thanks, Tony.
PS: My dealership told me that my engine at only 112,500 is toast for these reasons:
1) I wrecked the car -- even though I totally repaired the body, engine was not damaged at all and given a clean bill of health after accident -- and,
2) I did not keep up with oil changes every 3,000 miles (usually between 3,000--7,000, more than any car I've ever owned -- and as I said in my previous post, I have never expected my car engine to last as long as someone that keeps to that schedule -- or my neighbor who probably sleeps w/his car -- resulting in my car lasting only 240,000 before a rebuild while the other guy's car goes 280,000).
These reasons are preposterous as anyone that has even a cursory understanding of how automobiles work knows!!!! And to make the customer wrong/at fault while standing in the dealership looking at his dead Scion to which that same customer gave $19,600 of hard earned money, is also preposterous!!!!
Thanks for the ear, but also the support in advance,
Tony 2008 Scion XB Blown Engine Cause He Didn't Change the Oil Every 3,000 Miles Guy
Do you know that this is only 08 issue or what? I want to buy new engine or a used XB (love to buy a new one/lease it but not sure if i can afford a payment now) Am I crazy to buy another one? I love my poor car!! This issue is very painful and worse because my best friend is the service manager of the dealership where I bought my 08 new! Well I guess you read my last post, won't bore u....thx, tony
