Cut and pastes from oldschool to bring this up to date:

You may have been aware, I haven't posted any engine bay shots of this steed as yet... even though I've put some serious hours into cleaning it, as when I took possession of the car it pretty much had the entire road surface of Southland coating the under bonnet area. Well, it's always had a niggly oil leak from between the head and block, which has become worse as I've put more and more km on it (I've done almost 8000km in this thing during my ownership which I think isn't too bad for a weekender!).
On Friday evening, with the help of two certified Datsun fiends, Shannon (shandawg) and Craig (vegie) we embarked upon the mission to remove the head and rectify this problem. As the valve stem seals are also a bit worse for wear, I figured a complete top end recondition was in order. Here's a pic of the engine sans rocker cover, air cleaner and various other things so this post has visual impact:

Some problems were encountered. Not least of which, was the head bolts being secured with some kind of loctitey/shellac spec goo. All bar one came out intact (although not without a fight) but the last one snapped, thankfully leaving almost an inch proud of the block. Fingers crossed I can chase the threads and clean them up appropriately to accept the ARP head studs I have just ordered... (more money... sigh).
The head has been dropped off to the lads at Taylor Automotive for the work, they come well recommended and also provided me with a written quote prior to undertaking any work.
Otherwise, plans include a thorough clean of the radiator, new timing gears, chain, guides and crank seal, new waterpump, some judicious cleaning and polishing of various engine bay parts to dress things up a bit.
Deadline is Leadfoot - this could prove problematic.

Ok guys I'm trying to fix this alright.
Anyway, with the deadline looming, I still haven't had a finished head yet (turns out it needs new valve seats also....) and neither have the new head studs arrived.
But I have made some things a bit nicer to look at. Inlet manifold has been blasted, and coated with some good ol' VHT silver. Carb has had a minor strip and clean, and plated a few things as seen by the splash guard thing that sits beneath the carb.

I've acquired a new timing set, which looks like this... there was a waterpump in the box as well, but that looks boring to be honest.

And I also bought these off kicker a while ago, they can be a new restoration project in the works I think. 14x7 front and 14x8 rear. negative heaps. All going to plan I'll run a smaller tyre than I currently have on these.

Bit of the old shiny shiny

Holy shit I just posted cellphone photos also. Kill me now.
Anyway in other news, hit the car again on the weekend, had the sump off, changed gasket, installed timing gear etc and cleaned up various gasket surfaces. The radiator is off at the radiator man having a new core installed - it appeared to be working ok, but it is falling apart and 40 years old so figured prevention is better than cure, and have bitten the bullet to recondition it. On the flipside that too, will look nice and fresh in the bay. Otherwise, it's just scrubbing to do until the head comes back, and the head studs get here. Should look the part in there come Nats weekend!

So some productive productivity occured on this old thing today. Rolled out to Shannons workshop around 2pm to get cracking on the reassembly with Craig (vegie) rocking up shortly after to provide a knowledgable pair of L series savvy hands.
In addition to the parts specified above, I also ended up with essentially a new radiator (complete recore courtesy of North Shore Radiators) various seals and gaskets, and a brand spankers set of ARP head studs from the kind folk at Pro Parts in Napier (hit up Craig there for sweet deals and AMAZING service).
Step one was to scrape the old gasket from the block, as seen here with the ARP studs installed shortly after, to hand tight spec as per instructions.

Those with eagle eyes will notice the front cover installed, which incidentally has been all cleaned up (not polished

The head, recipient of a complete recondition by the folks at Taylor Automotive - not the cheapest option but provided a written quote, stuck to it, and also pretty decent service. This head ended up with new seats, new stem seals and guides, as well as the usual clean, skim and pressure test. Apparently the valve springs were a bit soft - to be fair, this isn't a race motor so we'll be fine.

The head in place, timing chain gear reinstalled and timed up correctly.

This is the last shot I got - since then, the radiator has gone in, leads, dizzy cap and everything else installed and connected - about midnight we turned the key to see if it would bring up oil pressure.... oh no! The tell tale red light failed to cease illumination after several cranks. In the end, the call was made to pull the oil pump out (and the dizzy as they share the same drive) and prime it. With a further few cranks, the light went out. Following reconnection of the coil, the car cranked and started as per usual. Success! At this point I haven't got water in it, one of the small old braided hoses has cried enough so if anyone knows of a hose that reduces from 3/4" to 1/2" I am all ears as this is what I need.
Otherwise, happy. Apologies for the super sub par images. At this point I must extend my sincere thanks to both Shannon and Vegie for their help, I'd be fucked without you jokers.
Hope to be rolling on Monday
/> Bring on Nats.
Edit: also bought some new wheels. Again.
