Possibly it is a two piece gasket that is backed to a harder/metal sheet like material, and the pressure of torquing down the bolts makes it separate. Not necessarily a defect, but a byproduct of pressure makes it flare out a bit......Or I could be full of crap! LOL

It's not uncommon to see a multi layer steel gasket split on the overhang however, if my eye's aren't deceiving me,that is a gap between the H/G , head and block, in post #143.
Not trying to start anything - just going by the photo posted. |

Yes , there's a small gap ( circled w/ RED ) in the M.L.S. head cylinder gasket of the #1 cylinder that was installed the 1st few days of Sept. , 2010 with 23,747 miles on it . That part of gasket does stick out from the block as you can see in the photos . Need to ZOOM in for a better look . The digital camera we have isn't that great .

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 . |

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? |

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 .

There's been a few other members that claimed to have or possbily have the oil leak , but they've disappeared .

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 .

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 :
