08' Yaris HB burning oil

[madtv261]

Hello Yaris World Community,

In the last three months, my 08' Yaris Hatchback has burned oil almost completely dry. Only when it's near the very end will the Oil Pressure light and Check Engine light come on. Goodyear was unable to help and the Dealer said they would need to do an engine tear down which costs $650, and then fix the problem which they estimated could be up to $2000. The car is nearly 10 years old and I regularly get the vehicle serviced, I love my car. I am not experiencing any kind of odor or smoke of any kind, but I'm wondering what alternatives I might have before I invest that kind of money into an older car. I do intend to buy a new vehicle by years end, but for now, does anyone have any advice as how I can fix the engine for a much cheaper price? Any help would be greatly appreciated.

Thanks in advance,

Kevin

How many Miles on it and is it burning or Leaking the oil ?

[madtv261]

Hey yarisfitch, 173,000 miles, and it for sure is not leaking oil as two mechanics have checked that

You fill by regularly checking the dipstick...not waiting for "the very end" or for lights to come on. This type of maintenance leads to an early very very end.
Ditto with coolant level.
And brake fluid level.

Right, but the point here is that this is just now becoming a problem of the engine burning oil. That is precisely why I'm looking for assistance on how to resolve this issue. I now have to keep oil in my car to top it off as the oil level depletes faster than before

Ok but you haven't answered a very important question. Do you regularly verify the oil level on the dip stick or wait till the light comes on?

[madtv261]

Since the second time this has happened, I've been checking the dip stick about every 3 days to verify oil level

defective PCV valve?

My wifes Spark had a issue (they all did) with a poorly designed PCV valve & would suck straight oil right into the intake manifold. Luckily I caught this early and spliced in a catch can. I had to drain it every 2 days until they had a recall with a better part. I still run the catch can but it gets a trace amount in 7500miles

[madtv261]

Malibuguy, thanks for the suggestion. With this in mind, i'll see if my mechanic can look at it to see if it warrants replacing. I'm a novice when it comes to cars so all your input is much appreciated

Well theirs the main error to start with. Once that red light comes on for oil.....engine needs to be turned off immediately and not turned on till the oil level is rectified. Also theirs quite often some premature wear if it's neglected to the point of having the dash light go on. Plus this happened twice. :/ That light goes on when theirs no oil pressure.

[Rigaud]

Also did you have your oil changes done at 5,000km intervals?

[madtv261]

Yeah, whenever the MAINT Required light comes on, I have it serviced. This is a new issue that I've now encountered twice. If there is something more simple than an engine tear down that is very costly, I'm hoping to find an alternative fix

[Rigaud]

Leak down test and compression test!!!!

[madtv261]

Thanks for the advice! I hope that's cheaper than 650 for an engine tear down

[IllusionX]

At this point, might as well just replace the engine.

If you're just going to get a new car at the end of the year, just keep it full of oil and drive it.

Otherwise, get a used engine and swap it in.

[ex-x-fire]

What weight of oil are you using? My wife's Taurus calls for 5w20, it uses oil when I ran that weight. I put in 10w30 & have no more oil useage.

[tmontague]

As stated earlier first to check is the off valve. Then do a leak down test. If it isn't a simple off valve Then I'd just do an engine swap at an an independant mechanic.

If you're engine has been run until the light goes on then it's been run lower than 3 psi (iirc) and could have some damage due to that. A new engine swap should cost around $ 1500 give or take.

Yaris engines don't just burn oil like that, either your pc is severely stuck open or something else happened.

what is an "off valve?"

[Bluevitz-rs]

what is an "off valve?"

Pretty sure that was an autocorrect from PCV (Positive Crankcase Ventilation)

[tarkus]

I am not experiencing any kind of odor or smoke of any kind.
This part doesn't make sense if it's actually burning oil.

Before paying someone to investigate further I would go ahead and try a new PVC valve yourself, I am guessing they cost around 10 bucks at Napa... Maybe double at a dealer :-) . Even without much experience, You can probably replace it yourself as there is not much to it. You can watch a video here. I think this site allows youtube links. If not just search for yaris pcv replacement or something like that.

I would still check again for burning oil. Have someone stand behind your car when you first start it up in the morning. You may see a quick puff of smoke once in a while that only happens on startup. That would lead me to believe its possibly your valve guides wearing.

Also have someone drive behind you.. If they see some smoke while driving this could point to being rings. But as mentioned before, a compression/leakdown test is good for really verifying that.

But either way... I would try the PCV valve first as its the cheapest. If that didn't work and since you are planning on getting a new car in the future, If it were me, i would just keep the oil topped off until I got the new car. Doesn't sound like it is hindering the performance or the way it drives at this point. This is assuming you are not keeping the yaris once you get a new car. So might not be worth the 1.5k to 2k investment of a new engine if you plan on getting rid of it in a few months.

Don't know how fast you are using oil, but if it was using it really bad it would be smoking out the tail pipe. These cars only hold a little less than 4 qts. I would replace the pcv valve, they aren't to expensive and can be changed in 5 or 10 minutes, check your oil every day, write your mileage down when you add oil so you will know about how many mile you can drive before it needs more. When you park overnight, try to park where the pavement is clean, then in the morning when you move the car look where it was sitting to see if there is any oil on pavement. Next time you have to add a qt. of oil, put a qt. of lucas oil stabilizer in it instead of oil, could slow the oil loss down and help with blow by. You can buy a lot of oil for $2000 dollars, I would just keep it full of oil and drive it, if bites the dust before you get your next car, just have a junk yard engine put in. These cars have aluminum blocks and it may need a new block, never know what you will find when it's taken apart, $2000 overhaul could end up being $4000 once they get into it.

Just another thought on your car. It could possibly have so much sludge on top of the cylinder head that the oil can't drain back down into the oil pan, would have to remove the valve cover to see.

makes a lot of sense considering a cat converter. belching clouds of smoke won't show up until one burns way more than qt/400 miles.

the OP didn't provide his oil burn number yet.

[ncp13]

Not even 1 liter / 1000km shows clouds of blue smoke..

Check the condition of your engine to figure out if your oil consumption is from worn piston/rings/cylinder, valve seals .

Compression test , leak down test , pull a spark plug and see inside or on the spark plug for heavy oily residue.

Thick oil is just a temporary bandaid and might work for an engine with loose tolerances .

good luck.
