    Once the plates were smooth and finished, I got to tackling the other bits that needed attention.

    First of all I gave it another clean, and then measured everything to ensure there were no parts out of spec that needed replacing...

     

    I purchased a new FD pressure regulator to ensure the oil pressure was upgraded, I located and FD rear stationary gear as they are hardened in the factory and had it machined to 12a gear specs.

    I threw the front gear in the lathe and machined a groove so the bearings that I modified with multi windows lubricated nicely.

    The new rotor bearings received the same machining treatment to bring them to MFR spec.

    Pressed a new  pilot bearing and seal in the shaft.

    Because of the nitrite heating process, I needed to press out all welch plugs to replace, and drill out the brass factory oil gallery plugs and tap with a hydraulic plug.

    A couple of weeks later the rotating assembly and plates arrived…. To my horror.

    I didn’t remember the plates returning so harsh when nitrited back in Nz.

    make a few calls, and sent a few msgs out in dismay but was resigned to the fact I was going to need to remove the slag looking surface by hand…. 
    Took to the task with rum in hand on the kitchen table and spent from memory 14 hours over the entire weekend stoning and then finishing with wet n dry sand paper

    Sooooo……

    this revelation happened just after I’d accepted a new job to move states from queensland to Victoria.

    I had the delight now of moving an undrivable car 1500kms.

    managed to achieve that, $1500aud as opposed to free if it was drivable because the company my new work used to relocate me wouldn’t shift a car with with no running engine. Bastards

    after a couple of months settling into my new role I whipped the block out and took it into work for a strip down and inspection…. Prior to this tho I’d located some replacement rotors and plates under the presumption my rear rotor, rear and centre plate were shagged.

    I found the culprit pretty early on in the piece…. The moment I removed the front cover I noticed the oring used to seal the oil feed to the block was pinched/damaged and was causing low oil pressure I thought was a dicky old sender…. Hmmmm. What a dick I am.

    Anyways… continued stripping the block down and was genuinely impressed, and felt rather lucky.

    Front n centre plates were in fantastic condition with next to no wear, and rear plate to my surprise just had some visible hotspots.

    so with my new found enthusiasm, sent my rotating assembly for a full balance, and my plates of for a skim and a nitrite.

    Fuck…. Been ages since I’ve updated this.

    and @oldrx7 has been pestering me for about a year.

    anyways, been a few things happen In between drinks.

    Drove this thing every now and then. While the 323 was in having an exhaust fabricated and a going over “pre-cert” inspection, my son was hankering for some skids.

    took it a few streets down into farm land and found a nice intersection.

    Motivated by my 3 year old son chanting “donuts dad, let’s do donuts”

    we swung a few “0’s and 8’s” to the amusement of the surrounding properties.

    as we exited out of the final skid there was a fantastic rumble from the gearbox… 

    to which my son thought it’d be a great idea to say “ooooohhhh… dad what’s that sound. It’s noisey”

    I wasn’t too worried…. Sounded like a bearing in the gearbox so promptly limped it home and parked it in the garage until I could be bothered whipping the box out.

     

    a couple of weeks later I did remove it, remove bellhousing and replaced I put shaft bearing. Full of confidence and pride for fixing it I promptly started it up…..

    hmmmm….. slight noise. Perhaps I just needa rotate and get some oil around to looob it all up. 
    quick drive out the driveway to end of cauldersac didn’t fix it.

    well fuck.

    thought it must be another gearbox bearing. So did the shitty task of again whipping the box out laying on my back under the car. Took it into work and stopped for inspection….

    apart from a the lay shaft bearing being a bit tighter than I’d like all seemed well.

    rebuilt said box with new synchros n bearings and again lifted the box from my back into the car…. You can imagine how old this was getting.

    I must confess…. I’m one of the laziest pricks so certainly don’t go to the gym…. So it’s bloody heavy lifting and locating on my back with my pipis.

    cut a long story short…. Next drive also had no change…. Still a delightful rumble. No I was right fucked off. 
    took a sample of the engine oil and sent it to you e lab for analysis, wanting to rule out bearing failure or suspended solids. 
     

    perfect!!! Said lab tech. A little bit of carbon but that’s normal and expected. 

    I was perplexed and rung the old boy who’s shop I used to kick around at to ask advice.

    he asked for symptoms, I told him and he laughed. Said… come on Jamie boy. You know what this is. Your rear gear is fucked. Pull the flywheel off and check. 
    so this is what I did…  but fucked if I was going to again remove the gearbox for a 3rd time off my back and remove the 54mm nut fixing the flywheel to the shaft.

    took ot to the shop that had done my exhaust etc and threw it on his hoist….

    guess what reared it’s ugly twisted head?!

    100% for reals it's what I'd do if I bought that car ... but reality is I wont buy it.

    you should get it, remove springs, primer and guide coat with titans.

    put your money where your mouth is.

    Nevermind mumsie. Its always better to apologise than ask for permission
