    Hello Prius owners! I am the original owner of 2011 Prius IV. What a fab car it has been for all 225,000 miles! Until last month the only maintenance it has has needed has been routine and recalls.

    Even though this is only my second post since 2011, I have been in here now and then, it has been such a great resource.

    It seems I missed all the discussions about Prius head gaskets. I guess it's an issue. And now its mine too, sadly. I am facing a huge repair bill. The dealer suggested a new (used) motor. I'm looking at about $2700. Ouch. He has a motor with 100k miles on it. That comes with a 6 month warranty. For another $300 I can get a 3 year warranty (parts & labor) on it. I'm wondering if I should I hold out for one with less miles. Or maybe just throw in the towel and trade it in for a new Prius.

    Those of you who have over 200k miles on your Prius, what say you? Should I sink the money into this old and reliable until now car and hope it isn't just the beginning of the end? My inclination is to stay with it for one more year and hope it goes two more. I drive about 35,000 miles per year

    The HG at this point has just a very minor leak, according to the Toyota dealer mechanic. The car drives fine, it does have the terrible shake upon a cold start and some rather nasty fumes until it warms up. A few weeks ago when the car was in having the EGR and manifold, replaced, he checked the HG and said it was fine. 1 day after the repair the shake and misfire codes returned. So back into the shop it went where it stayed for a few days, without much success at finding the issue. Finally, it was a re-calibration issue (not sure of what exactly, but that's what I was told). Anyway, the HG was looked at again, closely, and still no indication of it not performing properly. So off I went with just the calibration update, thinking all was good. A week later the shake and misfires returned! Several more hours in the shop and it is a very small leak in the HG that is causing the issue.

    Opinions please. Thanks.

    I would guess the egr colet was pretty much blocked with junk?

    I wish I had the know how and the time to do the repair. But that's not likely in my lifetime.

    Don't robots put these vehicles together in the factory? Maybe we need robot mechanics, too <ducking now> :)

    They didn't tell me if so. But a good guess, sure.

    he had a mechanic friend do it. at $100./hr, you'd be better off looking for a low mile salvage

    $3K installed with 3 year warranty seems the most direct option to me.

    Have a look through this thread, watch the videos: it's basically using a low mileage fourth gen engine, with some adaptions. The engines are around $1500, and for a mechanic to do this I'd think at least another grand? But you come out with a near-new engine, with 4th gen improvements, ie: better pistons/rings. The 3rd gen manifolds and EGR are retained, and there's some mods for the coolant lines.

    (He's doing this on a v, but the principals are the same. First time around he did the same swap on a third gen.)

    Thank you, all. One other question.... realistically, how long do you think it can go as is, with the HG leak? Being in New England, warm weather is at least 3 months away. I believe the HG prefers warm weather. I doubt I'll wait, I can't risk being out in the boonies during my travels and breaking down. I'm just curious.

    ^ This. If you trade up with a car with a knackered engine, you'll be lucky to get $500. If OTOH you do the $3K swap with 3 year warranty, and trade up 2~3 years down the road, with a trade that's still road-worthy?

    FWIW, our son recently did a trade up, going the $500 route. Their trade was truly knackered though, older, with multiple expensive issues: CVT transmission the main one, engine mounts, water pump, hybrid battery, and on and on, . The engine was ok though, lol.

    You could try some "magic" hg fix solutions. Look on YouTube, it's some stuff you put into coolant and it should fill up the cracks

    Low chances, but still...

    2700 is cheaper than a new car payment (assuming you currently don’t have a car payment)

    With that being said....I think 2700 is too high.
    1500-1800

    I would try some head gasket sealant, can give you 50k miles and by that time, you'll retire the car. This costs a few dollars and very little effort

    Not if it gets done at the dealer and comes with a warranty.
    If I am gonna pay $2700, I would pay another $300 and get the 3-year warranty as Mendel recommended.

    But if it was me, I would do a bit more research and try to understand the reason for the blown HG. If it is due to a wear&tear only, then I would remove the head and replace it myself in my garage. I think it can be done without removing the engine.

    You are the original owner of that car, don't let it go for the pennies on the dollar...

    Identical story happened to my 2010 with 220k.
    1. Tried hg sealant of brand a. It did seal the leak. few weeks later water pump died.
    Replaced water pump self, 250 baks. Flushed remains of sealant out. Happy :)

    Till winter came next month, when I realized heater core clogged...

    Flushed heater core self.

    2. Month later miss-fire again !
    Tried sealant brand b. It did promptly seal the leak and heater core. And Few days later promptly water pump died. Replaced water pump self 250 baks. This time around flushed heater core too. Happy :)

    3. 1 month later miss-fire back again “a little”
    Also noticed rattling of exhaust manifold shielding. Had a look - it’s all rusted through.

    Had a long sad look at all other rusted parts, broken plastic in multiple places, recalled the horrors of being stuck on highway for hours waiting for tow truck and and sold it.

    220k for $21000, it came out roughly 10k miles per $1000 - go find a lease like that :)


    Bought 2018 Prius Prime Premium even cheaper than 2010 Prius yesterday. Incentives on it are crazy right now, so hurry before they disappear :)
