Found : head gasket oil leak on 2 used 2010 YARIS ...

[yaris2010RS]

hate to be the one to bring an old thread back to life, but after removing my 2010 engine i took some pics. i think these will be the most clear pics in this thread and do point towards an issue with the head gasket sweating oil. Also possibly a new "ledge" to check for oil residue. Please keep in mind, i know i had an exhaust leak at my header, that is definatly not the cause of the residue. I will post more pics once i tear down into the engine more.





Edit to highlight key points

Green - Head gasket
red - Oil residue (sweating gasket) area
Blue - Exhaust leak
RED ARROW - seating gasket, THERE IS NO OTHER WAY FOR OIL RESIDUE TO GET THERE

Personally if I had this happen to me I would monitor the oil consumption very carefully.
Also I would put a piece of cardboard on the ground under the engine and park it there every night.

If the oil didnt fall much on the disstick and there wasnt much oil on the cardboard, I would leave it alone! Theres more trouble to be had by strangers I dont know if they know what theyre doing taking apart the engine and "fixing" it. Also, who is to say a new head gasket WILL fix the problem? What if it doesnt? What if the well meaning people at Toyota screw something else up?

If the compression goes south and the engine starts burning coolant that would be different.

Does anyone know exactly were under the HG the oil is coming from? Maybe that can be modifyed?

One thing bothers me is the reports of new Yaris's with overfilled crankcases. The oil needed is 3.7 qts probably they are putting four liters full in there. Could that do it?

This thread is painful to read, i'll be checking my block later... i did glance around there before i bought the car but now i'm going to check this specific area. Even if i am leaking, i would probably take bronsin's approach, i've had slow leaks on cars before that didn't cause major damage during the time i drove it.

I say , let it be . Our friends' 2010 has the same leak since new and there's over 125,000 miles . Just check the level every week .

I've found a few SCION XBs that have the same engine as the YARIS to have same oil leak . Not sure about the XAs . Rarely see those at used car lots .

Agreed. i don't see as many XAs out on the road either.

Hershey, lets not jump to conclusions and make a pandemic over something that isnt proven.

Please note i have been monitoring this since 2010 when i got my car and it was always existent but i never once noticed oil on the ground under my car, even after it sat for numerous days at a time. Also i never once noticed my oil dip stick dropped, even after i was boosted i only once noticed an oil drop and it was due to a seperate oil leak on a turbo line.

another note, my car parks in the same spot every night in my garage, the same way. there has never been an oil drip on my white concrete floor.

All that being said, this oil debris was visible on my 2010 yaris since about 4-6 months old (when i first checked)

I do believe My car is not a perfect example as it was oil changed at the dealer since day one and im not 100% sure they did not ever "miss" the oil fill hole. i do believe if they were missing and some was running down the back of the engine i would smell a burning when it hit the header and also the chances of just missing enough to run down the back of the engine and stop on the ledge without going any lower is a long shot. I am comfortable in saying some of this collection of oil and debris could have been caused from oil change sloppyness but i am not able to say that all of this has been caused from oil change sloppyness.

I will attach more pictures soon of the head gasket, from impressions in the head gasket i can say i did not see any failed points but the possibility of raw exhaust (carbon, oil, and other compression debris) blowing through the 2 piece layered head gasket.

Calling this a "Leak" may be premature and incorrect, i am still leaning towards the gasket sweating out between them.

Something else to note, the 2 head bolts on the timing chain edge did seem not as torqued down as the other bolts.

I'm fine with it now . It's oil under the pan .

No leak on my 06/10 manufactured 2010 sedan.

Hey everyone,

Just wanted to report that my 07 Yaris Sedan (automatic) is having this issue. I am well beyond my warranty in years but not mileage. Warranty will not cover the issue. The fix was quoted as "Engine oil leaking from front cover, reseal cover, replace front crank seal & valve cover gasket" for which I am quoted the price of $502.00 + tax

1.) Is this really going to "Fix" the issue
2.) Is this price fair?

Thanks for any help on the issue.

Well are you seeing oil on your driveway from the pictures I have seen I'd doubt anyone would loose more than half a quart of oil between oil changes of that so I'd say just monitor your oil level and then repair it when it becomes a issue or gets worse check your pcv valve

[Hershey]

I'd let it slide for now . Clean the areas and watch . Check P.C.V. as stated above and replace if needed . Takes about 15 minutes to replace . Longer if stubborn . Use an closed end wrench to get leverage . May want to check the rear corner and the back of of valve cover on the passenger side . That could be a a culprit . Remove any residue in that area . Would also clean any oil from top of the valve cover that may been spilled during oil changes . Do this when checking P.C.V.. I use window cleaner to cut through oil resdue / grime . You'd be amazed how well it works . Paper towels used to remove grime / oil .
