Could this be the real reason why the head gasket fail?

    What do you think about slightly overfilling the oil would lead to hybrid engine instant torque start pulling the oil to intake manifold? This would cause cold start, missfire and clogging. And maybe head gasket failure also?

    Me, my dad and many of my friends are type of people that thinks "more is better" in almost everything in life. I just think is this type of thinking (more is better) is usual in general?

    Is there lots of Prius owner had sligthly overfill the oil thats why there is so many head gasket failure?

    Ps. I dont have head gasket failure. Just bought my Prius V 2014 5 months ago. It run great. The service man slightly overfill the oil first time when I bought the car. Second time I slightly overfill the oil 3 weeks ago when changing oil. Im going to suck that extra oil out this week.

    As far as I'm concerned they fail for an adequately explained and researched reason: uneven heating and cooling.

    That's been popping head gaskets from every engine maker for 100+ years.

    What's the miles?
    How much is slightly? How much (in mm or inch) above top mark on dipstick. Up to 1/4" I'd just let it be.
    Long shot...
