leaky seal on engine? oil overfill? - Page 2 - Toyota Yaris Forums

I found some type of leak the other day after I changed my oil I looked like coming from the valve cover but I removed the plastic cover and I found that I spilled a little bit of oil when making my oil change.

no spill . Use a funnel and quarts .

Did the OP use a funnel? I find these new oil groups(ii + iii) used today to be more weep and leak prone than the old gunk used 7 year ago or more.

wonder if those that are using a lighter oil such as 5w-20 or a 0w-30 should look for this leak along the back of the engine block on the left hand side where the timing chain cover is and runs from the top down to the oil pan ?

removed the oil cap , lift the cover up , and used a flashlight to look for oil that may have been spilled during previous oil changes I've performed only to find it clean and dry as it was from the factory . So not my doing .

JEFF69dini , the technician said that the " BALL BEARING " you described is the source of our leak for the '08 sedan and that it's associated with the head gasket . Dye was used in the engine to locate the source . There's a ledge ( part of engine block ) above the " BALL BEARING " that is inverted that catches the leaking oil and mixes with the road dust , etc. . Then below the ledge it forms into a smaller square bottom where the oil drop forms ( this is looking up to the upper right ( passenger side ) hand corner of the backside of the engine block from beneath the car ) . Using a flashlight is very useful to spot the oil . Did you ever find out anything of your dilemma ? THANKS
