    I guess if you want the short answer the third gen is good for 220,000 mi before it needs all kinds of repairs. In my opinion it's worth it. Does anybody know if the 4th gen has the same head gasket issues?

    IIRC the PCV circuit is connected differently. Hopefully. it remove the need for an Oil Catch Can and not leading to head gasket issues.

    Which year(s) Gen3's?

    Was wondering and thinking might be a causation. Good to know.

    Where about in Michigan, does he work on Gen3's and can you disclose who or where? Guessing $150 was the labor for the $400 used battery? Where'd you find those?

    Thinking I'm going to do a custom modification to run the PCV valve up in between the head and coolant tank somewhere on the line going into the OCC. Good to read that here also. Any verification from a Gen2/3 or later Prius owner with the mod or how the design is on the later Gen's?

    Thinking while at the OCC mod and working on the Wiper motor repair if not replacement if the causation... will inspect and if needed clean the EGR circuit, Manifold, Intake, Sensors, Plugs and first and foremost read and watch videos about what all is where while at it. Thinking can use the stock PCV valve, drilled maybe out, as the adapter for the line going to the new PCV valve relocated unless for some reason I need a larger hose.

    At 220K I'm starting to get that cold engine rattling noise a little during certain acceleration events I'm not confident what those detailed exact events are just yet. Goes away if I accelerate slower or faster. Seems like an ECO mode MG change range in ECO. No error codes however. Thinking definitely time to disassemble and inspect the easy to get to intake related parts to clean and inspect for starters. I do need a new air filter also as the dealership noted, as of until recently they performed all maintenance other than tires at Discount Tires this last change, the rear brake pads I replaced since the passenger side lower caliper pin seized unfortunately and two oil changes I performed until this last one since is more cost effective to have them perform and am going through roughly 500ml oil per 4K looks like. Regular routine maintenance (Oil, one transmission flush/change, topped once the coolant tanks, topped once the brake fluid, few lights, few wiper blades, on the third set of tires, recall work or warranty work, new bumper guard yet to be installed, new driver side running/turn signal yet to be installed) and has been a champ. My super hyper miling motor home for a period also doing advocacy work at certain Universities and Base communities. Really impressive vehicle. I want the drivetrain in my 2001 Dodge Ram somehow easiest and want to make a engine welder/plasma cutter out of a MG. B^|)

    I was wondering also if anyone has performed the PCV relocation mod with the Gen2 also and just realized after looking into the Gen2 design, the PCV valve is higher up on the what appears as typical from my limited experience the valve covers.

    I'll create a new thread in the Gen3 forum.

    It is now Dec 2020 and my 2010 Prius has 219,000 miles. I just checked the Bettery Life and its at 49% left. I figure the battery will make it to 400,000 miles. Change the oil every 8,000 miles but last oil change showed I was burning a bit of oil so now going with every 6,000 miles on full synthetic. We have regularly scheduled maintenance done. Car has been in three small accidents in front and rear. Body panels in the front are missing the wheel well covers. Car is now used as the drive to work and home. Overall, this has been well worth it. Main concern is the body panels are in place by clips and a couple screws. But I do love my prius. Bryan

    Just as an FYI: batteries do not wear out linearly. They wear exponentially. Based on that 49% left, I would expect your car’s battery will fail within the next couple years, if not sooner. 219,000+ miles is still a good solid vehicle lifetime. But I’d start saving up for either a new battery or a new car.

    Correction. Save for a kit of new cells. Much less expensive.

    Interesting Dr Prius app cautions against using BlueDriver for $100, does not work with Prius specific individual battery module codes, or Dr Prius app, link below reviews Dr Prius supported OBDII scan dongles.

    Off topic......but God's gift to the motoring world is the 2021 Prius Prime, with a $5500 rebate and $4500 federal tax credit. A brand new, nicely appointed Prime for $20k OTD.....insane. And you can expect it to be the most reliable, efficient vehicle money can buy.
