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

" toyota put that black gasket maker in there? really? they made a mess of a job. "

Yes , this was the way we found it after the repair of H.C.G. at the TOYO service center . They also did not tighten the oil filter enough . Luckily I decided to look at it a few days after getting it back and it was so loose it had leaked to the bottom of the filter . I also was able to spin it off buy hand . Cleaned it off and retightened by hand along with a 1/4 turn of the cup / wrench . This is why we got TOYOTA to give us the free extended warranty , due to the shoddy work done on the engine .

Can you imagine how much of the black Form In Place Gasket ( F.I.P.G.) sealer that may have ended up inside the engine as well . I did several short runs of fresh oil and filter to flush out any that may have been inside the engine . This is part of the reason we'll be getting an U.O.A. for the 2008 sedan in mid MAY . Will post that .

This is also the reason why we and our friends ( told them of our experience ) are hesitant to get the M.L.S. h.c.g. of the 2010s' replaced under warranty . He has 65,000+ miles on his 2010 3 door . He bought the 4 year / 125,000 PLATINUM extended warranty at time of purchase . So , he's keeping his fingers crossed for the car not to develop any issue with the oil leak of his YARIS after the warranty runs out . We're using his car as a guinea pig since we only put on about 15,000 miles a year , which is well below his yearly average .

This picture is of a 2007 YARIS engine torn down at 102,000 miles , said to be due to an external oil leak and internal coolant leak . Good to know the PLATINUM extended warranty with 0 deductible is there as the mileage / years pile on .

Top view of the black M.L.S. h.c.g.. The area circled in BLUE is where the gasket is split ( gap ) . The area in RED is where the h.c.g. leaks oil from underneath the gasket of the #1 cylinder . Picture below shows the split in H.C.G. , circled in RED .

Add me to the list of leaking head gasket

Checked about three weeks ago when I came across this thread, and cleaned up the area and oil is slowly coming back in the same area.

Anyone consider getting a coolant fluid analysis as there is a coolant passage just to the top left of the cyclinder#1 and wondering if the oil is making its way also in to the coolant in addition to leaking out?

Im curious if you could give an estimate of how much oil this is? Is it measureable on the dipstick? The question isnt is oil going into the coolant but is coolant burning in the combustion chamber? Which should be apparent from white smoke and lowered coolant level. Also if there IS oil in the coolant it will be seen in the radiator when you take the cap off. (engine cold please)

See any?

Sorry to see that . You could get a U.O.A. to see if any coolant is present , like we did .

[Hershey]

If there's an internal coolant leak it would be very slight within the cylinder and most of it is likely to burn off within the cylinder . You'll notice there's more deposits in the #1 cylinder of the torn down engine above . We've just posted a U.O.A. in this section for the 2010 and no signs of coolant were present in the analysis . Plan to do oil analysis for it every 35 > 40,000 miles . Might get a compression test for the 2010 as well . Yes , there is some drop of the oil on the dipstick .

[Hershey]

There's been a few other members that claimed to have or possbily have the oil leak , but they've disappeared . . One said they found out through CARFAX that the head cylinder gasket was replaced on their used '09 and another discovered the oil leak when working under the car while installing fog lights . Maybe they're just playing with our heads .

LOL I was serious about the carfax thing.

" LOL , I was serious about the carfax thing. "

I'd hope you weren't yanking our dipsticks . Been awhile . How's it working out for you ? How about posting the CARFAX , if it's possible ( minus part or all of the V.I.N. ) . The more the merrier for those who disbelieve .

My first post here, cool site for yari owners!

I love these threads!

I have an 08 yaris hatchback 5psd 38k, and after reading all 11pages of this thread, I checked the block/head on my car and guess what.....OIL!!!

Going to clean her up (my engine compartment was fithy from some recent baja trips rally car style ), drive a couple hundred miles then put her on the rack for a thorough inspection. Also sending an oil sample to blackstone ASAP.

Hershey, thanks for being diligent on this issue, although it was a painfully redundant read, if it saves me (and possibly others) major repairs down the road then it was well worth it.

I'll keep you guys informed.

[Hershey]

If possible post some pics of the oil that has gathered . Would be an easy task for you with the rack . No crawling under the car , standing room . Good luck .

[Hershey]

THIPHIL , is the one that supposedly found oil on the back of the block while installing fog lights on his 2010 ( posted March 24 , '11 ) and then on MARCH 26th posted he was taking it to the dealer the following week . No word since .

[Hershey]

Then these's a post with a few pictures by GONZO452001 of possible oil leak in this thread on page 7 , post #123 . Never heard from again .

[Hershey]

Then there's this post ( 1/8/'11 , post # 83 , page 5 this thread ) by TXyaris finding the head cylinder gasket was replaced on his used 2009 by using CARFAX . Nothing since .

Yesterday we stopped by the friends for a visit and to get pictures of the extent of the oil leak from the H.C.G. of their 2010 3 door bought new in October , 2009 . The last time I thoroughly cleaned the exposed part of the black M.L.S. head cylinder gasket and the surrounding area was October 19 , 2010 with around 49,000 miles on it . So , it's been close to 7 months since last inspection . There's now over 65,000 miles on it . There was no oil leaking from the valve cover gasket and no oil on the top or the back of the valve cover from oil changes done at a TOYO dealer . I've posted pics from our 2010 3 door of same areas that were recently cleaned as his was in October , 2010 to give the BEFORE ( cleaned ) and AFTER ( around 16,000 miles later ) . Here's what was discovered :
