I also have a blue ‘68
Thanks mate, I'm near Melbourne too. We should have a drag race.
It's funny how my minor rebuild turned into a full blown tear down...
I took out the core plugs because I was digging some serious gunk out of the water passages.

I carefully scraped out and pressure washed all the debris and feel much happier with myself.

I gave the old pistons a wipe and while removing the rings I found that this one was crumped on the side. The ring was jammed hard in there.

I'm finding this process all really awesome. I've played with cars for many years but this time I have the time and space to really explore what I'm doing, it's great. I thought there were way more active members on this forum, but I think I'm mainly just recording a good log of this Datto.

Tomorrow morning I'm buying a gearbox..... 4th time lucky, right? Guys?
I highly recommend checking out this book "How to keep your Datsun alive" I bought it off a bloke in Texas on eBay.
