    I had an oil change and tire rotation done today, 9/28/24, at my local dealership on my 2013 prius C with 156,312 miles. The last oil change was done on 3/9/2024 at 152,160 miiles. About a month ago I checked the oil level and it was perfect. I didn't notice any difference since the last oil change. After the service, the dealership sent me the following text messages and images.

    oil leak from rear of engine possible rear main seal
    potential high cost repair
    diagnose oil leakage ((possible timing chain cover )) $199 diagnosis
    recommend reseal timing chain cover ((due to oil leaking))

    I just paid for the oil change and took my car. My plan is to check the oil level regularly and if it doesn't drop, take the vehicle to an independent mechanic at it's next oil change and ask about it. Maybe I shouldn't even tell them about it and see if they identify it as an issue without putting it in their head. I have never noticed any oil on the ground under the vehicle or any change in the oil level on the dipstick between oil changes for the entire life of the vehicle.

    Any thoughts about the pictures or dealership's recommendations. I don't think it looks that bad for an 11 year old car with over 150,000 miles on it, but I am no expert.

    it's very common to have some seepage. it is a weak point in toyotas design.
    most here don't worry about it, but it's a nice cash cow for dealers

    Around here it is $1200 or more for a timing chain cover seepage. I would have your mechanic clean it up and then check back at the next oil change for a visual.

    Seepage on an older car is usually okay to ignore.

    When it progresses to something you could fairly call a 'leak' with a measurable loss rate? That's when action is required- but it might never get that bad.

    I think you're on the right track.

    This may be a small problem related to oil overflow.

    The dealership reported an insignificant oil leak on my last visit with my 2012 Prius c, with an expensive repair quote that I put off. Today I read about grenading GR86 and Subaru BRZ engines due to Toyota using RTV instead of actual gaskets in cars dating all the way back to 2013, resulting in a class action lawsuit. Would our situation be from the same manufacturing design issue?
