So, I gave up on finding reasonably priced new ring sets for my Nos pistons. It was cheaper to buy this new re-production set out of Japan. The plan is to have a short motor completed in the next three months.

Nice!

I have decided to use engine #1002560. She is an early one with 4 sleeves. I partly dismantled and stored the engine around 10 years ago. Well lubricated, wrapped and dry stored. I also ensured the safety of the starting clutch surface by filling a small bag will wd40 and ziplocked it onto the front end. Most crankshafts fall prey to poor storeage and then become fairly useless. I did actually run this engine around 12 years ago and I cannot remember any nasty noises.

Unfortunately the NOS pistons shown on page 1 are useless as a previous owner machined one of the ring grooves for some unknown reason.
Glad I bought the Re-production piston sets.

Image 1 :The piston from number 4 had a bound in section of shattered compression ring.

Image 2 : Honda was clever in providing a threaded hole in the sleeve head, put a suitably long & long threaded bolt in, and wind it up. No nasty levers or hammers required. Also note, one of the best spanners I ever purchased, normal open at one end and a pivoted socket at the other.

Image 3: The last image shows the decay and rubbish inside the block.

No turning back now.

Hopefully the bases of the sleeve seats are OK and you dont have the same issue as John.
It's still a little perplexing how the single sleeves seal against each. Is it simply the head gasket does that job? But what stops seepage between the sleeves and out sideways?

AussieAS285

The bases look really good. Those four tiny rubber tubes do most of the work. The design relies on both the under sleeve gasket and the main head gasket. Not really different to the twin sleeve design.

Peter Davis

With the twins it relys on the under sleeve gasket. It appears then that the singles rely on the under gasket, the head gasket and the rubber tubes. I assume thats why the went to the simpler twin setup later. They really are complex little buggers

AussieAS285

I have recently wondered if they went to twin sleeve as the single sleeves might have a tiny propensity to move when pulling 7 ~ 9k, ending up in a misaligned crankshaft, or worse.

Spare sleeve #4. Initial inspection suggests prior deterioration due to water / rust. But the relatively straight line suggests casting imperfections. Either way, the sleeve is now useless as I can feel & see the opposite side to the deterioration on the inside of the sleeve.

The Denso brand Distributor. Cleaned up, old bearings & seal out. Ready for new bearings & seal. As silly as it may seem, sloppy bearings & a weeping seal can dramatically affect timing and a clean spark. Luckily, both the new bearings & seal are a stock size.

After three homes and one storage shed over the past twelve years most of the car is now in one place to be worked on. Space is at a premium. I am awaiting a new number 4 cylinder sleeve which is on its way from overseas. The two I have were not up to the challenge. During the wait in sourcing a new sleeve I was exceptionally lucky to find and be gifted the original matching numbers engine block for the car (Ie, matching the ID tag). Lucky I had not already assembled the other engine.

Kuroneko

That looks an enormous amount of space... To me at least. Looking fwd to seeing more. Neko.

AussieAS285

Yeah, the space is good, but normally occupied by my wifes Landcruiser. I only have days to find places for all the tubs and boxes (yet to come back from storage) before she claims the spot back. At the rear of the picture above the orange towel there is a sign, "Landcruiser parking only"

AussieAS285

After a long search this NOS number 4 sleeve has arrived from Canada to replace my faulty ones as previously pictured. Looks too nice to put in the engine.

Peter Davis

MT,
I assume you'll have to bore that out to match the others and fit the new pistons. Pity as it's a brand spanker. And wouldn't I love to get my little hands on all those parts you have!!!!
Good luck with the motor rebuild

My engine block was in need of new studs. A big thank you to Suzuki San from Spread Tool Japan.

Looking forward to this project. Please keep the updates coming. Subscribed.

Fun fact #2

Started more chassis work. finding the correct parts is interesting as Honda kept changing things. Probably just to confuse those of us 50 years later who decide to try a restoration.

AussieAS285

Fun fact #3

The chassis gets more interesting. Lots of parts updates and changes, some only changed number due to a newer supplier and may have been the same part, just different manufacturer.
Some were an improved part.
The chassis generally could be viewed as early and late, but there are in fact four variants for convertible.
A bit crazy given the cars were only produced for approximately three years.

any update(s) ... ?

Kidhuf

In for updates I love these cars.

Kuroneko

Any progress? Noting today we've possibly got the largest collection of S-cars under reform or restoration here than anywhere I've seen before...

AussieAS285

Sorry no updates.
Our business has been slow which requires more of my time, leaving little to no time for the car.

And yes, there is a great number a S cars under reconstruction here. But we all seem to suffer the same periodic issues which results in the projects stalling.

Photo 1 is of the chassis which was blasted, zinc primed and powder coated in June 2005

Photo 2 is the same chassis 10 years later, out of storage, given a wash and looks near as good as 10 years ago.

Will bring the chassis into the garage later today with the aim of actually doing some work. Both the car and I are not getting younger.
