Is it weird to get attached to things purely because they have lived a long life?

No. You can trust that thing. You can't necessarily trust the thing you buy from Bunnings.

I would prefer cheap mineral oil for break in

I'm with you. It's kinda six of one, half dozen of the other. A good mineral diesel oil is actually a really good choice. High detergent, because diesel, no friction modifiers (because diesel engines are typically low speed engines). Perhaps that's less true now than it used to be though. All the high speed diesels in those shitty Mazda Karens and the like have probably meant changes for diesel oil formulation.

Interestingly, my petrol toyota engine specs the exact same oil as the diesel variant of that car, and guess what, those petrol engines are known to last forever and be clean as a whistle inside...

True of almost every aspect of cars really... 

food for thought, brand new OEM performance cars don't use any form of break in oil either.

Not really comparable though? 

I would expect a brand new performance engine to have been assembled in a very clean environment using high quality components and have most variables finally controlled. Heck, that'd probably include the knowing how much "material" the first oil fill will need "hold" from the break in process (if they are not being broken in on a dyno and having oil dumped immediately after). 

Not quite the same as refreshing an engine that's had a spun bearing go through it or similar where you're re-using some parts that may or may not be hiding a plethora of debris. 

Cost of engine rebuild? Many many thousands usually, $$ you save using plain mineral/something else oil vs break in oil for the first change? $50 - $100 if you're lucky? Break in oil is not exactly expensive. 

Good mineral diesel oil ~ same cost as break in oil anyway. Would rather use the product specifically designed for the process personally with my extensive engine building experience (1).

I reckon not, performance or not they get slung together by a person that does the same tasks every 90 seconds for 8 hours.

I'll bet replacing an occasional engine in warranty is just an understood cost of doing business, most of the time they are lucky, sometimes they are not.

your Speedflow invoice

Could have bought another JDM shit box with it.

I feel dirty there are 3x Aeroflow fittings on my car, but I didn't put them on. Already have 1x Speedflow fitting to replace. 2x more are on the Plazmaman plenum on the underside, too hard basket lol.

I received a package the other day from @Komdotkom he said to me I hope your wife has a sense of humour (not sure her sense of humour would extend to this). A few days later this turned up.

Thankfully Im usually home before the wife so I could intercept the parcel. That particular day I got home and nothing had arrived yet. An hour later I heard something at the door so I opened up and there's my 8 year old daughter holding the above box, she hands it to me and says daddy you've got a parcel. Thank god she didn't read the return address or give it to my wife. Dragon lady crisis avoided, lol.

I don't have a pic on hand but inside the package was a RB head drain. Funny looking 3xl rectal probe that.

Going along with the theme of this build which is budget focused (tight arse), I found a couple of hydraulic fittings from work with sufficient ID to use on either end and some 19mm nitrile rubber hose. Working in a rubber factory has it's perks, occasionally. It's not pretty but will do the job.

I did mine in the BMRS crimp on stuff, the -16 fittings for the dry sump were quite expensive.

That's as far as I got before having to go do dad things.

I'm thinking on going with a .8mm washer to shim the oil pump relief valve. I could double up and run 1.6mm.  Just trying to keep the oil pressure same as before as the bearing clearances are bigger now. Do you guys reckon .8mm should be sufficient? Don't want to over do it.

I've kind of settled on the idea of .8mm but the pan hasn't been put on yet with sealant so can change it.

At least you know how to change it if it's not enough! It's a pity they aren't accessible without removing the sump (and the engine)

It's done now, the sump is on and buttoned up. Went with the .8mm,  engine builder suggested 1mm and shook his head when I said 2mm. Time will tell.

If it's not enough, can always run this stuff, lol

    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
