Just wanted to do my part and contribute to the thread I have been reading ever since I noticed the oil problem. Did the test, got the repair done car runs great! Feels like it has a little bit more power with the fresh rings and pistons. Below is a picture of the receipt I received and also the top of the new pistons after about 200 miles. Looks like a little layer of carbon has already formed but I have read this is actually normal and good.

Don't forget to tip your mechanic

My 09 Scion tC fits the specifications of burning oil it's been doing it for about 6 months it got so low that the light came on 1 time I put 2 quarts in and it was ok but I have had a ticking sound in my engine ever since that day. So I have 2 questions. 1 I have been putting Lucas oil in my car does it need to be regular oil do I need a oil change is that enough to get the Lucas oil out of the engine and ok to do a consumption test?
2 if they do see that it's been a manufacturer default. Will they fix the ticking caused by the lack of oil in between changes.

I have a cas # and am going to dealership tomorrow just hoping I could get a heads up on what to expect ..
Thanks

The less that you talk, the better. There is no need for you to tell them anything and no need for them to ask anything. If it is time for an oil change, have them change the oil and seal it for the start of the oil consumption.

if they do see that it's been a manufacturer default. Will they fix the ticking caused by the lack of oil in between changes.

Yes they should. Just make sure that you have them note the ticking noise on the repair order and the oil consumption when you get your vehicle written up by the service adviser. Documentation is key here.

** They may recommend other repair work be performed when they rebuild this engine so please be prepared to do as much as you can. It will help everyone in the long run.

So if it does need to be rebuilt some may come out of my pocket or they may want me to buy new plugs and coil pack and everthing to go with the new engine to keep it on the road for best life of engine im guessing

Also I just had the oil changed last week but don't want to wait to see if it's a defect or not I had a limb fall on my scion so I'm at the point where i either need to keep the car if everything is fixed to par and have the work done ie paint and body or just sell it and cut loss I have been thinking #2 before I found out about the enhanced warranty so I feel like I'm in a super rush to figure it out

 

[Wareaglecp]

They said that there needs to be no Lucas oil in it so I have to have the oil changed again then capped and sealed ... Anyone know how much oil stays in engine during a oil change ? I don't want the Lucas oil to effect the oil co u test

So, I have a 2010 Camry Hybrid. I have been doing all my own oil and filter changes since I bought car with 22k on it just about 3 years ago. Nearing about 52k. Have always used Mobil1 0-20w. Couple of questions. Does an aggressive driving style result in more oil consumption? Second question is does a hybrid have a different threshold for mileage or consumption? In theory, a hybrid application would have less run time on it than a conventional car traveling the same mileage due to the hybrid system that shuts motor down as often as possible and eliminates idling time in traffic, etc. I am currently doing my own test before taking to dealer so I have my own set of data. Does the dealer have to perform an oil change or will they initiate a test on a properly filled engine? Thanks

i can only answer the last question threw my experience yesterday.... They want either a receipt that you just had a oil change and they would check and top and seal it up or have them do a oil change. I had to flush the Lucas oil I had in mine out so I payed the 40 for the oil change and of course my head gasket had some sort of leak I think it was just from it being 111k miles on engine but like oishiiJPN said you be prepared to do (pay for) as much as you can. In my head I was like hell I can change the gasket for less then $20. But it was on the rack with oil drained so I sucked it up payed the 140 for the new gasket. I'm glad I let them do it as the mechanic noticed that whoever at express that fills the oil with the gun pushed something and bent it there near the oil fill and it was hitting when he was putting the head back on and he bent it back in place something I wouldn't have noticed so to everyone who goes to get oil done other then dealership tell them to be easy woth there fill gun.... Anyway hope this is some help.... Also, I was wondering if interstate travel or city travel consumes more oil... I'm going on a road trip but don't want to if it keeps my engine from doing what it normally does but i add oil constantly so if they don't get it the first time I know they will the 2nd. It's very noticeable when checking your oil if you vehicle has this problem or not. I'm so glad toyota is doing something about the problem.

. Does an aggressive driving style result in more oil consumption?

I would say yes but I am not an engineer so there's that.

Second question is does a hybrid have a different threshold for mileage or consumption?

No, not according to the test procedure.

Does the dealer have to perform an oil change or will they initiate a test on a properly filled engine?

Not necessarily. They should just be able to confirm that it is at the full mark (not under/over filled) and then seal it so you can return in 1100-1300 miles for re-inspection.

Our 2007 Toyota RAV4 4-cyl (w/120 k miles & maintained regularly) needed a qt+ added between the 3k normal changes. Toyota sent us a "recall" letter so we took it in & paid the required $30 to change the oil & "seal" our engine. Returned after 1,200 (but not more than 1,300) miles. We qualified for the "oil consumption repair" but they informed us that on average owners are responsible for $1,000-$1,200 in "additional required" costs that aren't covered by Toyota in the recall/warranty work. They stated that getting our engine "fixed" was such a bargain that we would be stupid not to take advantage of the repair option & shouldn't complain about the $1,000+ in costs we have to pay out of pocket. Does this seam reasonable to others who are dealing w/this ? We've have a good relationship w/our dealer to date, but this seems odd to admit to a factory design problem and then require $1k or more to have the repair work completed ?

Ok, let's start with this and go from there on a good foot.

This is false and you are not required to pay for any additional repairs. Now there is some extra work that would be beneficial for you to have performed on your engine while they have it out like, spark plugs. If you simply buy these then they would install them at no charge. There are many other items that would benefit you here but I am not going to list them. Here is a great post on this subject from awhile back..

Again, there is no required out of pocket expenses, only additional recommended repairs. It does sound like they are giving you the hard sell on this one.

Is this your normal Service Adviser that you deal with every time you go in for service?

Thanks for the quick reply. Yes, this is our normal Srvc Advsr who in past dealings has seemed fair/honest. Your past posts link leads me to believe the $1k-$1,200 quote is for valve seals, timing belt etc. that they "suggest" (vs. require) be replaced while the engine is torn down anyway. His verbiage was "you'll need to plan on spending $1k+ on the parts required to do the job correctly which isn't covered by Toyota under the warranty." I appreciate your response - sounds like we just need to suck it up & pay for the extra work as a smart investment in the long run. Just have to trust the dealership/Toyota is treating us honestly as there's no way for the consumer to monitor what's actually done during the repair - naive maybe but I don't like to live suspicious of everything out of our control. Merry Christmas & New Year

 

[Lewis]

pay for the extra work as a smart investment in the long run.

That's exactly what it is and if your in a position to do this, your that much better off in the long run.

Merry Christmas & New Year

And also with you.

Hello everyone...newbie here.
Has anyone had the test done where the tamper-proofing procedure was not done...meaning no sealant and or zip ties were used by the dealer? If so, did they claim you tampered with it?
I ask because I've just about concluded my test; (1,210 miles on it) I popped the hood and found that no tamper-proofing was done by the dealer and now I'm concerned they may claim I removed the tamper-proofing devices and materials.

Thanks in advance for any help!

I'm the owner of a 2007 Rav4 Limited that I purchased in October of 2006. I've had all but 3 oil changes done as required at the dealership where I purchased it from. My Rav4 currently has 187, 000 miles and is going through the 1100 mile test to see if it is consuming oil. I just found out about this problem when I had the oil changed and then heard knocking 1500 miles later, checked the dipstick and there was no oil. I was told that it was my alternator going out. After having the alternator replaced and probing them about the low oil. I was told that it was a qt low and they could do an oil consumption test to see if it was consuming oil. I was never told that it was a nationwide problem with a certain engine. We'll see what happens in 600 more miles.

UPDATE:
I took my car in to the dealer today before reaching the 187 miles shy of the 1100 miles due to the engine running rough on start up. It failed the oil consumption test. Now I'm waiting on some gaskets to come in. I was told that I will get a call next week to set up an appointment to bring it in to start the repairs. I hope that they don't take any shortcuts and follow the repair procedure that Toyota has to the T. I will update when it is all done.

I got my 2007 Solara back from the dealer today. They replaced the short block and replaced piston rings among other things. I also had them replace spark plugs, belt and water pump (which was leaking) on my dime. It runs like a champ! They had the car for almost 2 months, but Toyota paid for a rental for over a month. Very happy with the service I received. This forum was very helpful. My only recommendation is to be very understanding and patient. I checked in at least twice a week and the dealer was great. They don't want your car taking up valuable space any more than you want it there. They are handcuffed by Toyota corporate, so be friendly.

Why did they only pay for 1 month rental when it took two months to repair? I'm just wondering do they have a set timeframe that they pay for.

When I was first told that I had to have a oil consumption test performed, I had the same problem. I'm just thankful that I looked under the hood before driving off. There was no tamper proof seal on the dipstick and because of that, I made them show me everywhere that they had placed a seal.

They won't pay for the rental until they accept that your car is covered. Once it is their problem to fix, they will pay for the rental.
My engine died due to the fact that the oil got so low that it burned one of the cylinders due to lack of oil. They had to tear the engine apart, take pictures and write up a report before Toyota would allow the fix. Before that I had to wait for Toyota to agree to pay to even tear the engine down. All of that took almost a month.
