    It has the large o-ring that stays on the block, but you might want to get an OE one as the one it comes with doesn't like to stay in the block. The other ones can usually be reused and are not a big problem if they fail.

    Some pop and some don't. I never really paid attention to which ones do and which ones don't. All I know is I don't remember ever felling one was loose. I did have one break off inside the block. That was fun.

    I've never had problems with the threads in the block, so I doubt you do.

    Avi how much do you charge at your shop for this repair? My 2012 Prius at 170k miles has now also developed the head gasket failure.

    I called Avi, fair price including parts and labor (he replaces the water pump as well).

    I believe I will be taking a stab at it, I have most of the necessary tools.

    Critic, thanks for the parts/cost breakdown and all the tips. I was looking forward to seeing some of the attachments you posted, however, the links are not working (at least not for me; for attachment 166855 I receive an error indicating that the attachment could not be found ).

    Mendel, thanks for the video and repair manual attachments, I am taking notes.

    Avi, thanks for the heads up on the water pump, I ordered an AINSI from Japan off ebay.

    It looks great, and the machine shop seems to be fast! How long did they take? By looking at the time stamps, was it only one day?

    Critic, did you use the two FIPG tubes? I'm debating whether purchasing one or two.

    Thanks,

    They originally estimated two business days but their other jobs were on hold due to parts being on order. So they had my cylinder head completed same day.

    My tube dispenser tool broke the first tube so I had to use both tubes.

    One tube is probably enough but it does not hurt to have a second one on hand.

    I'm curious: you didn't remove the engine? Assuming no, you applied the FIPG to the cover not the engine? From start of application to install, where you under +3 minutes* (from commence of FIPG gasket)? And then install and torque the myriad bolts by +15 minutes*? I would assume you did the applications of FIPG at the engine seams on those seams, not on the cover?

    I guess long story short, what were your impressions, the Repair Manual instruction vs realities of the the cover install?

    * Repair Manual stipulation, maybe a little nuts?

    The engine was not removed for the Head Gasket repair.

    FIPG 103 was applied to the cover. FIPG 103 was also applied to the engine on the six seams. No, I did not use the coolant-specific FIPG on the coolant contact areas - I do not know any tech that does. I also did not measure the thickness of the FIPG beads but from experience, I applied an adequate to slightly excessive amount based on the size of the sealing area.

    It probably took me around 5 minutes to get the FIPG applied and the cover seated onto the engine. From experience, FIPG is not super sensitive in this area. I had the bolts snugged up within several minutes after that point, but I did leave out the bolts for the water pump and the engine mount until 10-15 minutes afterwards. Even without the water pump and engine mount installed, there are enough bolts on the timing cover to maintain pressure on the sealing surface. The important part is to have both surfaces 100% clean, oil-free and to not disturb the BEAD of FIPG when mating the cover to the engine.

    Doing the repair with the engine removed is probably ideal but it wasn't worth the extra time to me.

    Not sure what happened to the original pictures, but I think these were the ones that were posted.

    Hi The Critic,
    i'm a big fan of your posts here and on BITOG. Strong work on this! it sucks to know the HG problem can happen despite the extensive maintenance you did. is this also an issue in corolla cars with similar engines?

    Thanks. If you look over on Toyotanation, there are reports of HG failures on the corolla as well. But it is not as common, but perhaps the corolla section does not have the same user base as this forum. In my conversations with technicians, the HG issue affects corollas as well.

    The 2zr-fe engine (Corolla) has no external cooled EGR. It's internal.

    Pixel XL ?
