    Hi fellow Prius friends. I am new here and have already benefited from all the great advice, but I decided I should cover all bases and post my concerns for advice.

    My 2010 Prius (purchased new, 165k+ miles) flashed the "low engine oil pressure" alert yesterday for the first time. I understand it's in reference to the extremely low amount of oil, and I realize how dangerous this is to the engine.

    About two months ago, my electric battery took a turn for the worst and was diagnosed by a Toyota dealership. I ended up going with a Green Bean Battery replacement instead of Toyota's service (so far so good). While at the dealership though, I was given a list of things that need to be serviced, including the reseal timing cover, which Toyo would like $2,549 for.

    I have an appointment scheduled for today at Pep Boys.

    My question is, will getting the reseal timing cover help/fix my low engine oil pressure? I have yet to notice any oil leaking from my car, but I'm not sure if that tells the entire story.

    Yes, I will learn to check my own oil, especially with driving around my older baby.

    Any supplemental or additional advice will help. It's my first car and I've done my best to care for it. I had less than great parents and family members who have never cared to teach me anything, so this is all new to me.

    Thanks everyone!

    Cover reseal is a rip-off and not required, as for the oil light your engine was starving for oil and probably did damage.

    welcome!

    agree with tank^^^ reseal timing cover is a dealer money maker. they all weep, and it's not even enough to see on the ground.
    what happened to your car is this:
    the egr circuit clogged up (most do around 100k) this caused the engine to burn oil due to poor pistons and rings)
    what you need to do is fill the oil to the top line, then check it every day. once your comfortable with that, space out the checking to a wee, month etc.

    the idea is to know how much oil it is burning by mileage, and keeping it topped up.

    and you need to get the egr cleaned

    all the best!(y)

    You need to check your oil level and top off the oil before driving any further.

    I have a 2011 Prius with 160,000 miles. Dealer in Folsom wants $2600 to reseal timing cover. No oil on ground under car - though it was almost a quart low when I checked (before maintenance). The dealer said it leaks onto a plate under the car, which makes no sense to me. I'm going to monitor but am worried it will be something that could cause a breakdown (getting ready for a road trip). Based on what I am seeing here, this could be a wait and watch issue (monitor oil use).

    Take a look down the passenger-side end of the engine with a good light. That whole face is the timing chain cover. For a better view, remove the front passenger wheel, remove a few of the plastic fasteners on the plastic line at rear wall of the wheel well, flexed it back and you will see the extent of the leak (if any). $2600 is steep btw, most typical reported here is around $1700, which is still a little steep for what's involved.

    "The dealer said it leaks onto a plate under the car, which makes no sense to me."

    The 'plate' is a series of plastic covers fastened to the bottom of the car (to improve aerodynamics...). Probably what the tech is referring to. They are likely to catch oil leaks. You need to get into the habit of checking your oil OFTEN, or you will have a breakdown.

    just top it up and check it everyday, until your comfortable spreading out the checks into longer and longer intervals.
    it is much more likely that you are burning the oil than losing it through the chain cover.

    have you researched cleaning the egr circuit?

    It is probably "seeping", not leaking. If it was leaking, you'd see mess from the oil.
    You might also want to check the oil pressure switch, it's located in that area and some have
    replaced it and the seep went away.

    I would do as Mendel says and pay particular attention to the silver colored area seen between the spokes of the harmonic balancer. That's were the crankshaft seal for the timing cover is. It the oil is found there, it is a simple and much less expensive repair in that it can be done by just removing the harmonic balancer, levering out the old seal and pressing in a new one.

    It tis quite common for most any engine with 100k miles to develop a leak in the front crankshaft seal.

    The cause of low oil pressure is more likely a worn out or defective oil pump.

    Or just low oil?
