Toyota Avalon Engine Questions



  • Here's an update on what I did...I replaced the VVTi line with the standard part, not the all- metal part because the dealer said the all metal part would not be warranted on the Avalon. Why doesn't the dealer recall it? - because 75% of customers buy the extended warranty through 100K so they are covered until then and the dealer is willing to roll the dice on having to replace the engine. Anyone looking for a great looking, silver 2006 Avalon XLS with a new VTTi line covered through 100K? No dings, dents or scratches. BTW, also fixed on this Avalon were: Steering Column Noise TSB#ST002-06 and ECM Calibration Enhancement to Shifting Performance & Smoothness TSB#EG029-07. Ex.cond. except subject to losing all oil at unpredictable intervals. Make offer:)
  • Mylast, are you saying that your dealer said the metal line would void the warranty, or just that he would not install it for free under warranty?

    Most dealers have taken the position that they will not replace the VVTi line with all metal unless the customer pays for it,( "customer upgrade"). The Avalon warranty stays intact.

    If your dealer is saying that the metal line voids the warranty, I would find a new dealer. That establishment is being less than honest.
  • popsavalon is correct. The Toyota V6 Oil Line Scandal is discussed in the website ToyotaV6OilLineScandal at the following link:


    The metal line was originally a Lexus part and can safely be used without voiding the warranty.

  • Paul3637, thanks for the link information. I think folks that are aware of this problem should work really hard to see that ALL Toyota V6 owners know about the site.

    It is really hard to understand all the horror stories being posted about this problem. It seems that almost no one is clean, from dealers all the way to Toyota Corporate.

    Hopefully this problem will continue to gain exposure, and Toyota will be forced, maybe by a class action lawsuit, to acknowledge and fix the problem permanently for their customers.
  • The new web site : should be visited by all 2005-2008 Avalon owners. It has most of the pertinent information related to the major VVTi oil line failures that are being experienced by owners of Toyota V6 2GR-FE engines.

    Worst case oil line failure can be sudden and catastrophic, resulting in loss of engine oil and almost certain engine damage if vehicle owners attempt further vehicle operation.

    The site also addresses failure responses by dealers and Toyota USA, which have been less that stellar.
  • Just in case everyone has forgotten, there are still roughly 1.5 million 2GR-FE V-6 engines out there with VVTi oil lines that can rupture with no warning and dump all the engine oil on the ground, or highway. Toyota USA has never officially acknowledged this problem and dealers have been wildly inconsistant in dealing with it.

    There is a proven fix for this problem, I'm not so sure we are there yet on the "unintended acceleration" issue..
  • Would somebody please explain to me how this has been a issue since 2008 with still no fix. I think it is computer related and they have not figured out a fix without having to replace the whole system at $600-800 and have just started to design a new brain to fix the problem they new they have had for several years just like the oil line. They denied it until 2009 and all they did was put a heavier rubber line on instead of the $168.00 fix for the metal line you could buy and have installed. :(
  • Thursday my wife filled the tank in our 03 Avalon and within 200 yards the car was dead. The engine turned over fine, just wouldn't fire. Had is towed to a reputable shop, they can start it running by priming it, but it quites and blows lots of smoke. They think there is diesel in the gas. Wife says there is no way she filled it with diesel. Have not heard of any other problems from this gas station.
    I'm at a loss. Told the shop to drain the tank and try some known good stuff.
    Any ideas?

    Here's some free thoughts to get you started... Diesel gas pump nozzles will not fit in gas diesel is in the tank. To be sure just siphon out a hose full and look at it, smell it or burn some carefully. Also, put some in a glass container and see if it separates. Anything "clear" is probably water.

    How do you "prime" a car with fuel injection? If you mean hook it up to an outside fuel feed source, ok... it should run fine if the problem is the fuel in the tank and all else is well... if not, the problem is with the engine or the electronics.

    Hope this helps, others may have more ideas..... ;)

    By all means SAVE a gas sample when they drain the tank (if in fact, the problem is fuel---it may not be). By saving a sample, you can possibly make the station pay for something.

    Diesel fuel stinks, so the garage should be able to spot that in 10 seconds.

    I'm thinking this is an electronics problem, just on the face of it.


  • My 2003 Avalon has no power sometimes after first taking off. When I back out of my driveway in the morning (after allowing it to warm) I will have the gas pedal pushed to the floor and the car will not have enough power to get out of the driveway. I will then let it coast back in the driveway and turn off everything (heat or ac, radio, lights, etc) and give it a little gas and back out fine. When I turn my heat/ac or anything else on, it loses power again. Once I get on the highway, it will do just fine with everything on...what could be the problem. Thanks for any info!

    First off, we'd need to read some trouble codes, to see if anything's stored in there.

    At this point, we can only guess blindly---sounds like you might have an alternator issue.

    Hey- Have you ever gotten to the bottom of this?

    I'm having the same trouble. 1998 Avalon. Runs really rough only hot, intermittently. Starts to happen after a slow down going from high speed to lower speeds. Once it starts it normally keep happening until the car is shut off for 10 - 15 minutes. Sometimes I can take a 200 mile trip with no trouble, then later on it happens randomly on 5 or 30 mile trips. If it happens it always goes away after a 15 minute off period.

    Thanks for any feedback.

    Wild guesses: Thermostat sticking; water passages or hoses clogged from trash circulating in the system; low coolant level: electrical sensor problems.... others may have more ideas. Ever clean the cooling system? Hope you find it... :)

    I can't find your step by step on cleaning the IAC Also looking for proper method to check MAF sensor status. I need to figure out the wires on the harness to test.
    I cleaned the MAF but the P0171 returns after a few starts

    If anyone can provide a copy of the Canadian Limited Service Campaign notice for the VVT-i oil hose problem it would be much appreciated.

    I just had to replace my engine after 35,000 miles, because of this issue and Toyota Canada will not stand behind their product claiming that there was no such "Limited Service Campaign".

    Many thanks
  • As you might know, if you import a vehicle from the U.S. into Canada, you require a letter from Toyota Canada if it is a Toyota stating that there are no outstanding recall repairs against the vehicle. Of course, this becomes one huge issue especially because the dealerships do not want you to import vehicles for less cost from the U.S. and thus create huge obstacles to provide such a letter.
    Other high end manufacturers like Mercedes, BMW, Volvo deliberately make life difficult by asking huge sums of money pretending it to be some big deal and safety could be compromised.
    In any case, after fighting with them numerous times, I discovered, Dep't of Transport will accept a printout of a cars history which clearly outlines what had been a recall and if it was fixed. What I do now if I am bringing a car from the U.S., I simply ask a dealership in the U.S. if they could give me the printout of the cars history. Toyota has everything on every vehicle and they make a point of checking that regardless of where you are...Mexico, U.S.A., Canada. It is a way for them to justify repairs if the vehicle has changed hands etc..

    So, what I am saying is this. Try to go to a Toyota dealership and charm a service manager to print you the history of the car...they have it available online and ask if there were any recalls or any outstanding recalls. You might find the answer you are looking for.
    Also, I would Google recalls on your Model Toyota and you might find it there since it is a mandatory issue if it involves safety.

    I hope this helps??
  • Yes. I have copies.... go to this link for copies of both

    Within that site are links to copies of both the Canadian version and the US version AND all the newspaper articles and press releases ....... this affected 1.6 million recalled vehicles.

    Toyota Canada Recall(s): Shortly after the first Toyota USA campaign letters went out, Toyota Canada sent out a letter to affected vehicle owners dated November, 2009 describing a "customer satisfaction campaign" " that was almost the polar opposite of the U.S. version as to what vehicles were covered. It covered all affected models and years: 05-09 Avalon, Rav4, Camry, Highlander, & Siennas (but like its USA counterpart not 100% of VIN numbers are covered), It does explain the possibility of engine damage and it does create a sense of urgency telling the recipients that upon receipt of this letter, contact any authorized Toyota dealer and make an appointment - the campaign is a limited time offer. Copies of the letter at t=405&sid=cddcab9df7b3dff5f107868b6a187506 post # 415 and t=15 post #17. The letter does not describe the replacement part, but it appears Toyota Canada is using the same cheap fix as Toyota USA post #97.."So there you have it folks, the great Toyota fix, it's effectively useless long term, worth just enough to pacify the buyers and get you over the warranty period to a point where they have no accountability! Brilliant! Absolutely brilliant!!! So glad I did mine and replaced it with the complete steel pipe! best 150 bucks I have ever spent!" Yikes - update December 3: t=420 post #423 Canadian dealers refusing to install the all metal oil line. Update 2/14/10: Dated February, 2010, Toyota sent out the IDENTICAL recall letter it did last November but to more vehicles so that VIN #'s that were missed in the original mailing are now put on notice.

    I have copies of everything you might need if the links don't work. Email me at (it's listed in the website).

    I am Paul3637 on all toyota forums. I suggest you going toyotanation which has lots of Canadian members, too. Post your problem in the gen6 camry forum.
