    What a fascinating thread. I am so envious of you guys who can fix their own cars! I can do nothing but drive them! Great job man!!

    Lots more progress today.

    1st pic is just to show the liner that was pulled out and replaced on the block (I hadn't shown that before).

    The others show what I accomplished today so far. I finished repairing the minor pitting on the block gasket surfaces I noted earlier.

    Then set out to install the micropolished crank and new main bearings.

    I plastigauged everything to ensure all the clearances were good. They were perfect! 0.0015". The axial play was also right at the minimum spec (which means room to wear). 0.1mm

    The pictures show the progression, ultimately ending with the crank 100% installed in the block and all torqued in and assembly lubed.

    Next the pistons go in (tomorrow). Since I only have 10 (2 more on order) I can only get that far before my next Eurospares order arrives! Then the rest of the engine goes together!

    Is there no need to dynamically balance the crank, pistons and rods?

    No, there is no need and it is not part of the OEM or repair process. Each engine piece is precision weighted. The rods are all matched sets (within a very tight weight tolerance). The pistons are also carefully manufactured for consistency.

    Lot more tolerance for weight on an I6 or V12 than on a cross-plane V8, too.

    Coming along beautifully.

    I will also echo what the others said.
    Great thread, great skills and a big thanks for taking the time to share that with us.

    Today's progress...

    Started with a cranked block. Started inserting pistons and rods. Plasti-gaging and connecting to crank. Put the one new piston in that I have in hand but could not finish the job as still waiting on 2 pistons to arrive.

    So... right now, if you look carefully at the last pic you will see I have a V8 Ferrari in a V12 block! Would be better for gas mileage I suppose...

    My Eurospares order won't get in until late next week so the engine reassembly will sit silent for a week. I will finish a few bits on the interior but the major push will start back in another week.

    Cheers!

    Gee... I'm a bit surprised to see that the main bearing caps have only two bolts. I guess I'm too used to looking at American iron...

    That just means fewer nuts and bolts for me to torque and plasti-gage! I will take it!

    I am seriously getting to the point where I just really want to drive this car! I got it now about 2.5 months ago. At least I am now seeing the "re-assembly" side of the project!

    I drive two Alfas and a '07 F1 Maserati QP (with lots of similar DNA to the 612) but I can't tell you how excited I am to get this car done and driveable! I think I am going to love it!

    Feels like work now, but this is a car I will likely keep forever. Too much time and bloody knuckles into it to consider selling.

    :)

    I assume it's because the stresses are divided across 12 pistons/rods as opposed to 8 for similar displacement in some american iron?

    Old Pontiac big blocks usually had two bolt mains because they were beefy where Chevy had four bolt main caps on performance motors because they were smaller. I'm no ferrari mechanic, but I'm pretty sure generally that the pistons are smallish? Cylinder for cylinder, relatively low torque? Doesn't surprise me really that they don't need four bolt main caps.

    Look like forged rods with all radiused edges. Main bearing caps are big.

    OK, FINALLY, some more progress!

    My parts arrived today. So the 2 other pistons plus lots of other stuff. I finished putting the other four pistons and rods in the motor, so it is now a V-12!

    Pics show cleaning of sump, $800 of new connecting rod bolts (gotta hate torque to yield bolts), and the engine as a V-12. Then showing sump and assemblies starting to be put together on the motor.

    Tomorrow I will finish the front and likely get the heads on! That's a really big deal. I am getting pumped. Engine should go back in next week.

    You need an engine stand mate.

    I'm also curious if we have confirmed the new pistons weigh the same as the old ones ...

    wow trygve, you're admirable for your dedication. Yeah, if someone is so into mechanics as u, Ferrari maintenance is definitely not a problem, lol.

    As far as an engine stand, yes, I have one. But no way this engine can mount up to it without a lot of custom fabrication of mounting brackets. As such, I am ruining my back!

    I this and threads like this. Learn so much and all goes to my qualification as an armchair mechanic! I remember reading the Tom Yang site back around 99 onwards and it just sucked me in. Since then I've really grown to love car mechanics to the point where earlier this year I bought my own Ferrari V12 requiring a refresh/minor restoration. I hope one day to be knowledgable and brave enough to take a project like this on.

    Massive respect for tackling this build, and thanks for documenting the process along the way. Can't wait to see pictures of it completed.
