Thanks 'D'. [refer to post #8]
There seemed to have been a lot of dickin' around when a quick look with a flashlight &/or a mirror would positively identify it in under 60 seconds.

quote from Dman
"The A10 was the only A series Datsun engine that did not have provision for PCV.

Have a look at the block under the exhaust manifold at the rear. If there is a metal tube sticking out to the side, or if there is a machined hole with some sort of plug in it, then it is NOT an A10.
If there is no tube & no hole in the block to allow one to be fitted, then it would indicate that it is an A10 engine.
There are other indicators but this would be the main one."

This is spot on as my early a12 has the rear breather tapped to make it look like the a10

The timing cover is also a 1972 A12 type. Datsun 1000 engines used the early type used by the first A12s.

Wow, a Datsun 1000 with matching-numbers A12. That is worth something.

lol, ok ill forget the A15 idea ...

I've got a A15 in mine... it makes transmissions explode.

Thanks fellas ...

As far as i know its all ok :)

Maybe one day an A15 :) but for now its all good :)

if it is in fact a restamped A12, but it matches the compliance plate, and your rego papers, then as far as the law is concerned and any insurance company then no you need to do nothing.

Also, Im pretty sure that you can infact install an A12 into a 1000 without getting it engineered. it just needs an engine number change done. at least here in WA it is.

Its odd that someone would restamp the engine, unless they wanted to convince a potential buyer that it was all original and therefore worth more. I dont believe that it really applies to the datsun market significantly (unlike the falcon and monaro nuts). I would be impressed by an all original thou, but would struggle to pay much more compared to a non- original engine model.

Personally, I wouldnt bother. It looks neat and tidy in there, an as long as everything is legit on the papers, just run with it.

Typical toolbox letter punch font.

There is a way to get it (font & Numbers) perfect but leave that for another discussion.

Basically the font is wrong, the font size is too big, numbers all over the place.

Here is what a stock casting sequence should look like, neat crisp and perfectly straight:

You can see in the pic of the carby side that it has a block ventilation pipe, so going from the other Thou/A10 experts opinions in earlier poasts, it would seem it is a restamped early A12.

ok here ladies ...




Would the grind and re number be done for ease of registration?

If it is in fact an A12 then would it need a Mod Plate?
