    If you repair it NOW, before the gasket goes completely, you'll minimize the damage. The head may not be warped.
    Or it is minor and you can shave it by using sand paper on a sheet of glass. But you'll need a calibrated straight edge to check it.
    The longer you wait, the more head gasket material gets blown away and the more coolant will get into the cylinder and as was
    stated above, you can't compress a liquid, something has to give!

    Okay I'm doing head gasket. Anyone have any literature that would help with the process?

    Also @danlatu has a thread;).

    He’ll probably chime in as well with support (y).

    Struggling a lot with the passenger motor mount. I have all bolts off but it's a weird location and I'm not sure how to get it off. I'll try again tomorrow. Everything else is off though. Except egr cooler. Hopefully fpv with me narrating will help someone in the future. It's just with my cell phone.

    Have you jacked the engine only up?

    I believe that is the trick but haven’t done it myself.

    There are links to @Ragingfit 's YouTube videos of engine swapping here

    Yeah for the engine mount watch @Ragingfit 's videos, linked above. It's in a somewhat odd-ball location in the forums, since he was doing the swap on a Prius v, and "technically" it's a "mod", since it a fourth gen engine going in.

    I'm not sure you need to remove the EGR, or the exhaust manifold, prior to pulling the engine. @Ragingfit pulls the engine, then notices he's left the exhaust manifold loosely connected. I'd suspect if you only remove the connecting bolts between exhaust manifold and exhaust pipe, leave the EGR installed (just remove the pipe between EGR valve and (removed) intake manifold), it'll all come out.

    If you do pull the EGR cooler/valve first, note: in @Ragingfit 's videos he has a royal battle with the lower stud below the EGR cooler. You don't need to remove that stud, just the bolt on the end of it. it's then possible to pull the cooler out and off the stud. You could watch @NutzAboutBolts EGR cleaning video too, pinned in 3rd gen maintenance forum.

    First and formost though: I don't think EGR removal is needed as a precursor for engine removal, it can be done after. I think, purely armchair mechanic here...

    One more afterthought regarding the EGR: @Ragingfit installs 3rd gen EGR system with 4th engine, and it has NO connection to the engine, basically spans, from the exhaust connection to cooler, to the EGR pipe connection to intake manifold. And it's plenty stiff. If I'm ever removing our EGR again, I may not reinstall the nut on the lower stud, make life a lot easier.

    The Repair Manual even says to leave the intake manifold on, but it seems to me it's expedient to remove it first, if only to make more room to maneuver the engine as it comes up and out.

    thanks for all the info, you've been a big help! I will keep an eye out for the video, im not sure lifting the motor will make enough room for the mount to come out, but thats the next best option. It looks like it needs to go straight up because theres a stud holding it in place, but because of the ac lines it does not have the space to go straight up. i would be dissapointed if you had to disconnect ac lines to remove a motor mount. Im confident im doing something wrong.

    As far as the cooler goes, thats the reason why I havent taken it off. I also believe it is possible to remove the head with the cooler attached. I do think ill have to remove the nuts and studs in the back, luckily i have experience removing all of it. I know the bolt which you speak of and yes its a pain, but not impossible. Nutz and boltz video really did help me out. If I get a motor it will be a gen 3 i dont want to do any mods.

    As a small side note, I just cleaned the throttle body 500 mi ago, and it looks just as bad now as it did when I first cleaned it. The catch can is a must, thats way to much oil to be pushing out. Although, i did notice blow dryer like wind (blow by) when I removed the oil cap. Crap now I am thinking a new motor is the better way to go about this. I seen some for 600 shipped on automotix. I would like to know what you guys think about this. Thanks :)

    Motor mount removal starts around 2:50 of video 6 here:

    Swapping in a Gen 4 Prius' 2ZR Engine into the Prius v | PriusChat

    Before removal of motor mount (and transaxle connector bolts), he puts a floor jack with some blocking under the oil pan, to support the engine. He uses what looks like a 4x4 on end, to reach up to the pan underside. I'd be inclined to put something atop the 4x4, to spread the load more, just in case, say a square of 2x8, screwed onto the 4x4.

    And yeah, no need to disconnect AC lines, going from memory they have some flexible connectors, and once the motor mount is off the lines and compressors are just pulled out of the way.

    Got the mount off. Now I'm struggling with what socket to buy. @RyanFlorida said he used a 12mm double hex bit. But he states the manual calls for 10mm double hex (bihex). I don't see 12mm double hex bits anywhere. I do see 12mm triple square hex bits. Anybody have personal experience Here?

    Is this for removal of the cylinder head hold-down bolts:

    (PDF of excerpt attached)

    IIRC @Georgina Rudkus mentioned some key words in another thread, and when I searched those I ended up on Amazon.com, found this:

    Yea that's what I've come up with as well. But @RyanFlorida mentioned that it didn't fit, that he used a 12mm. I'm thinking he used a 12mm triple square? If that works I would rather get a triple square set as they are more useful.

    How do these cam bearings look?

    Not sure how to tell where the leak is. Perhaps someone knowledgeable comes around.

    Also I can say unequivocally that xzn ie. Triple square 12mm hex works. I will say that it is very likely that 10mm double hex works to remove head bolts. Reason why I say think it will work is that I inserted a 10mm hex and it fits snuggly.

    Just AutoCad musing:

    upload_2018-10-27_18-44-19.png
    I'm not sure how the 12 mm triple square is defined as "12". If a face-to-face 10 mm (single) hex fits snugly, then I think the right side pic must be the correct size. Then I just reverse engineered a triple square on the left, such that it's point-to-point dimension matched. It's basically a little more "pointy".

    There's a couple great pictures of what they look like. One member took measurements of both sockets and took pictures. But in the end the more common xzn socket works. I'm just upset the info wasn't as clear and wanted to make a post about it for anyone in the future

    The can bearings still look clean, but as long as you're there already, you could replace them, seeing that the first one has some form of scouring?
