    Odd I thought there was a change in both M1 and M2 for gen 4. Changing the power distribution curve.

    Gen 4


    Gen 3

    MG1 (Motor Generator) and MG2? Yes, but that’s the transaxle that changed; the engine is almost identical.

    If you're going to do more oil changes yourself and are still under warranty use factory parts so the tech doesn't know. In case of a mechanical failure the aftermarket parts will cause you trouble. And do the factory recommended services at a dealership for the warranty.

    Oh you are referring to only the ICE the Prius “engine” consists of ICE plus MG1 plus MG2

    I wasn’t aware the engine oil circulated in the transaxle too; tell me more…

    Overkill? Our dealership is aware i DIY. Their advice: keep your receipts, and a log. I do make all purchases at their parts department.

    My response was to your “the engine is the same “ obviously not - accept the facts

    You are expressing an opinion or choice of terminology and insisting that your opinion/terminology is fact.

    As a member of PriusChat for 12 years, I have never seen anyone but you call the ICE plus the MGs as the 'engine". In my opinion, Mendel is using "engine" they way nearly everyone here does.

    I understand your rationale but you are making a choice. I'd like to see examples of others using the term as you do. Otherwise, please don't put down someone else for disagreeing with you.

    Hey I bow to your linguistic expertise. And still waiting to hear how oil change frequency impacts the function of the transaxle “portion of the engine”.

    No sarcasm intended. BTW, my choice for ICE + transaxle with MG1 and MG2 is Powertrain.

    No it doesn’t. The ICE is the 1.8 litre engine. You want to include MG1, MG2 and the PSD, that’s part of the powertrain.

    It is nearly the same as the 3rd Gen Prius. Same engine code, just with updates to the combustion chamber for more complete mixing of fuel and air.

    I don’t have the exact plans so I cannot say for certainty if every bolt lines up but if one is willing to make mods if necessary, yes that engine will fit into it the engine bay of a Gen 4.

    Here’s an example of a Gen 4 engine going into a Gen 3

    It honestly depends on what type of vehicle you have.

    There would be no good reason to put the 3 into the 4.
    It's usually putting the 4 into the 3.
    Head and manifold is different, and the pipe from the head to the egr cooler is different.
    It would have to be bent to fit. I believe that was using the Gen3 egr cooler.
    But I thought I read someone also used the 4h egr cooler. I don't remember what modes he made
    to make it fit.

    Putting 4th gen Exhaust Gas Recirculation into 3rd gen was physically doable (with pipe bending), but there was some reports of problems post-install; maybe the computers are programmed specific to third gen EGR components.
