Hi , I looked at the cylinder block , now I understood how S20 is made . I see now water line , oil line , and each holes has each purpose. At the rear end of the block , “B73” on it . This is stamped on the every crank cap .And this code must be on the left side of the block with a brush paint which is made by quite bigger strokes . I haven’t seen it yet, so that will be my next challenge. And the oil pan , it is bigger than the L-series Engine. Max is 6 litter, I am feeling this Engine becomes nicer about oil pressure when the oil quantity less than 5 litter. Kats

Jim , nice tools !! Chris , hope you get the set of tools, fantastic! Kats

Hi Carl , yes we have salts everywhere in Japan !! Especially on highway entrance with slope . When I was a kid , yes cars put tires with spikes ,and whem I was a teenager , the government stopped using the tire with spikes due to the pollution of dust from the road . Recently, Nissan dealer servicemen did a nice job for my Z432. That is a clear coat for underneath of the car .I am so satisfied with it , it turned out very natural appearance, not glossy, it is very hard to tell the car had the coat. I hate salts ! Kats

Nice pictures , a lot of homework ! Kats

A common trouble of the tensioner , as the bolt pushes the the collar, a plastic bush inside of the collar gradually collapsed, finally the gear scratches the collar, then break it . My spare engine’s tensioner has slightly worn out , so I will replace it with a NOS one . And the chain guide which is located between the camshafts , there is also a common trouble of cracking at the both sides of the ends . As the chain goes to be flexible, bounces on the guide , it makes the guide stressful. Courtesy Mr.Watanabe ( owner of PS30-00063 ) for the pictures which show a damage for each parts. Kats

The pistons, I found a cool thing , original pistons are numbered on top face , from 1 to 6 . On the other hand, a new piston which I have is supplied from Nissan is not stamped on it . Cylinder liners are NOS . The original pistons are very nice . But I am wondering can I put original pistons into the each corresponding cylinder even if I use a set of new cylinder liners?

A chain tensioner is adjustable manually . Don’t tight too much , no chain noise isn’t good , some noise is good for the chain. I tried to display the electrical ignition system , but I didn’t want to open the plastic bag because I have got the used complete set from the seller of the spare engine. Note : S20 comes with Mitsubishi components such as a starter/ an alternator/ a distributor/ a voltage regulator / a transistor ignitor. Kats

Hi , my No.2 S20 Engine is confirmed for its good condition. I couldn’t stop myself doing this , taking a picture of the S20 gears location. I guess Alan would took same photo when he was rebuilding his S20 . People would always ended up doing this ! Note : the two chains are original , it has old type shape. We say it is Hyotan shape . Nissan provides still now but they are oval shape. Although in the illustration , the chain looks oval type. Kats

Blue , I really enjoyed seeing this manual , this is telling exactly the locations where the rust spots can be seen most of cars , including my Zs . I am now wondering did we have similar treatment at the Nissan dealers back in 70s in Japan ? Kats

Hi Chris , thank you for the pictures, Her Majesty brings her tools , could the tools be later production than they should be ? Also nice to see the red handle has some unique variations, interesting !! Kats

Thank you , the book is very interesting and full of useful information. Just great ! Kats

In this book , January 1955 , Datsun 110 went on sale . And B10 , Datsun Sunny was released in April 1966 . Kats

Hi 240 in OZ , thank you so much giving wonderful information, your input backs up our decoding method. I was thinking about other Nissan cars , they might have the same coded Jack and tool , and now it looks like true . Your 1969 B10 has Jan 18th 1969 Jack , Bingo ! I don’t know why O means 1969 . In this method A means 1954 . We need to see older cars have this coding . Long journey. Kats

Congratulations Terrapin Z !! The jack had been waiting long enough until you found it , what a miracle. Yes I see P F Y , that suites your car perfectly. Thanks for sharing this story. Kats

Thanks Chris , Gavin ! I hope the work will be easy . Also I am praying the head pass the leak test .The S20 is sometimes notorious for crack around valve sheet ring. This one is not the auction one , but the seller is the same person from the auction one . Kats

Hi , I picked up my spare S20 , I am so happy that now I can see it closely and I can list up what else I need for this engine . I see the head needs some fundamental work such as valve guide replacement, sheet ring replacement. And , the biggest problem is , No. 1 and No.5 Spark plug hole is something weired, someone drilled the sparg plug ,then plug’s metal is remaining in the hole’s groove. This makes me nervous, I have to find an engineer who can remove it and clean the hole . I don’t want a re-coil method if I can avoid. Other than that , parts are all in good shape , I don’t think I need to put my NOS parts into this engine.I will use this original component as much as possible. I will show you rest of parts when I am home . Kats

Comparison back of the solid emblem family. Kats

Hi Blue , thanks for the picture and your statement is very interesting, we need to discover it . Today I would like to show you this , A Fairlady-Z ‘s solid metal quarter emblem , an ultra early emblem . I have got this recently, and this is Right side quarter emblem as you can see “R “ on it . Attached pictures show the difference between hollowed metal emblem and solid metal emblem. I found the solid emblem is a little bit thicker than hollowed emblem. And it is so heavy to compare the hollowed emblem. I am impressed with this solid emblem is so clean and shiny, almost identical to the hollowed ones which are literally New In Box . I asked the seller if he has a solid Left quarter emblem, but he did not . As we already know , nearly 1000 Japanese Zs ( L20 and S20 models ) were produced by the end of Dec 1969 . This quantity is almost double of export S30s ( L24 model ) , but I cannot be optimistic, it is so hard to see the early production Fairlady Zs nowadays. Kats

You see the single defroster line “ dead “ . Kats

Thanks Gavin , it could be AU market car . Does AU market car have a set of “ lowered coil springs “ like Euro cars ? The car looks slightly lowered at front , the gap between the tire and the fender .Optional item chosen ? This morning I took my 240ZG as a commuter to an airport. In a cold rain dawn , but comfortable cabin . Kats

Hi Gavin , I still don’t get what they are joking about, let me review it again. Today I have a question, what country was this red car be exported? The red must be #110 , RHD 260Z , And interesting turn signals and , it even got the fuel filler door knob !! This crisp and clean exterior make this car looked so beautiful , I wish we could’ve have this car in Japan . No exterior mirror , front grill, bumper over riders are my favorite features . Kats

Thanks Gavin , I did not know there are some venders out side of Japan . Even they includes the eight shape gasket ! No need to ask Steve . And thank you for sharing pictures of your jewels , you did it your own , having fun and saving a lot of money . Here is a genuine Mikuni gasket kit just for your reference. Kats

By the way , the left choke disc is an early type , the right one is later type . My spare set of Mikuni 40 PHH is an early type which has straight-head screw for securing top cover . They must have an early type choke disc but , later type is on . Today Mr. Shimoura ( Hakosuka GTR And ZG owner ) gave me an old picture attached on a wooden frame , he told me the engine is for KPGC 110 ( Ken & Merry GTR ) because the oil cap is a black plastic , and the carburetors has Philip head screws for a top cover .And the choke disc is a later type . Kats

About a Mikuni Solex carb , what everyone is doing about this , eight shape rubber gasket . This gasket is not listed on a service manual / parts catalog because it is not meant to be disassembled. Please see the pictures, you see the eight shape groove on the cast jet block body . If this gasket deteriorated , fuel is not supplied correctly. However , overhaul kit never including this gasket . This gasket is sold by a few venders . The gasket is described “ Factory Mikuni made “ . I have some , yes I think they are genuine by the looks . Each one cost 1000 JPY ( 10 USD ) ! How come this is available, while overhaul kit does not have it . Anyway , I have bought some from a local Mikuni service shop . @nix240z , is there any chance to make this by your hand ? If demand is large enough , a price will be less than 10 USD ? Kats
