Hi David Not sure how much use this is to you but my Australian Austin MK2 has 12 stamped on the cam and top line on the case is 62941097A bottom line is AYH 0576 3 69 unknown if this is original dizzy sorry. Thanks Nick Found this info in my Gregorys Austin 1800 service manual. Sorry about the bad scan. Distributor 1.pdf (336.9 KB) Distributor 2.pdf (313.46 KB) May or may not be helpful.

Compression tests done
Good Call Dave
No1 1st cycle 125psi - Second cycle 160psi No2 1st cycle 125psi - Second cycle 150psi No3 1st cycle 125psi - Second cycle 160psi No4 1st cycle 125psi - Second cycle 160psi
Considering engine mileage I would say HC wouldn't you. I forgot to ask dad to see if the head has duel springs. I confirmed the Carb ventilation with an old video, unfortunately you can't see the engine number!!
I have written to Tony. It seems the list of cars has not been continued. He thinks that some real examples of the Mk3 engine numbers would be the way to go, if I want to be as sure as possible. I will continue to Improve the list when I find out more info.
Wolseley1800 I would be interested in the details of your twin carb wolseley engine for my list.

Thanks for the Info Chris I will add it in.
Hold off on the pictures for the moment, I will make a couple of amendments first. Can you tell me what your engines were Austin, Morris or Wolseley? Just to confirm the 301B engine has no PAS pump. The book has a change point in the Pas pump section that lists the 301B and a couple of others, that don't have the Sb noted (Yellow on the sheet). I thought this was odd, although the change was at H32766 so well after your engine. The Auto boxed were all good except one odd one not listed as Rc!!
Sorry haven't worked out putting quotes in yet. I'm sure its easy just need to have a play!
David
I think you are quite right about the importance of HC/LC. I will get Dad to do a compression test for me. Not sure how it will go because the car isn't far off showing me 00000 on the Speedo for the second time!! 190000 miles ish from memory. I will let you know what he gets.
Sorry I made a Typo in the post saying about LOCA having any information. I meant to say LOCI. Loosing the engine number is not a problem with Australian Crabs as the number is stamped into the block.
I am already a member of LOCI. Good Idea, I will inquire if they have any info and talk to Tony Wood thanks David.
If anyone else can help with there engine details please feel free to post them and I will compile the info in my list and post the updated one. Particularly interested in the MK3 Engine but any others would be Great.
Thanks
Nick

Hi David I did see a bit of dodgy stuff in the fiche so I agree it can't be trusted. It is only a stab in the dark really anyway! I don't think its a military engine. It would appear that the higher numbers are a better bet though to me. I dont know how many engines were made all up, but it seems to me there should be only a couple of numbers to choose from, on what was really a standard car. Hence the interest in real numbers from Mk3 engines. They would be lazy and use one number for most I bet. The standard car is the one I am looking for really 10000+ made. Are you saying not 651E or just ignore the LC, as appart from that 651E it looks like a good choice to me?
Ta Nick

Thanks for the Carb vent picture Wolseley1800. Here is a list that I have put together to help me fathom out what I should do. It may be helpful to someone else with the same problem. It is taken from the information given in the microfiche and the parts book I have. Please let me know if there are any errors or omissions and I will change it. 18H_Engine_Reference V2.pdf (257.3 KB) As far as I can make out there were a lot of options, most of which show very low engine numbers for any change points. I have to assume they were special orders. The bulk of engines made, it would appear, come in 6 main choices. That is if you have an engine number over 10000 like me. For a car with an alternator, this goes down to 4 choices as far as I can tell. I don't think my car had temperature control, "AA after the 2nd prefix" although I am not sure exactly what that was on the 1800 engine. That means my engine could only be 651E as far as I can see. All options fit I think. This seems to go against the MK3 being mostly High Compression though. The Fiche only lists change points up to L16127 for 651E, no high comp "H" engine changes that I can see. If anyone knows otherwise please let me know. This I think is where I have settled, unless of course the car turns out to be High compression. Then I give up!! I would really like to get some info on the engines that are out there and still alive. Anyone know if LOCA has any such info? Nick

Not sure what happened to my previous post so apologies if it appears and I am repeating myself now.
Thanks guys you have jogged my memory.
I went to the Beaulieu auto jumble one year and managed to get a long centre branch S exhaust. I wanted to make it twin carb so this was a major find for me. I didn’t get an inlet manifold though. So in the absence of the proper inlet manifold I made my own (No EBay or Internet). Basically it was made out of a single carb cast manifold. I cut it up so I ended up with a couple of little stubby sections. I then welded a plate to them to allow the carbs to be bolted on to the head individually. No balance pipe between them, just a port on one for the brake servo connection. Very dodgy linkages, as I remember, but surprisingly it worked ok. I have to admit so does tipping petrol on the air filter, obviously with slightly let emission control!!
Now this is this thought that may help me. I remember the original carb had a port on it that I had to block off. This would suggesting carb crankcase ventilation wouldn’t it? I don’t remember a port on the rocker box cover though. I’m not sure where the pipe went from the carb vent, I can’t remember. The other carb was from dads scrapped MK11. I don’t think it had the port from memory. That must be why the PCV valve is very familiar. It would have been on the MK11 engine from dad’s car.
So the Poor old car was being run without crankcase ventilation or any kind of carb balance or proper mixture control!! I was sure it was better at the time though!! Of course it would have made more power with the single carb, silly me!!
When I finally got hold of a proper inlet manifold I did the needles and springs at the same time, because I realised the mixture was a bit dodgy and fitted proper linkages.
Still to this day no crankcase ventilation though!! Ops!! This I shall have to rectify. Thanks for the warning Wolseley1800. In my defence I was young and dumb and on a quest for more power!! Oh well you live and learn!
I have my doubts about it being 476 now as looking through the Micro Fiche at the change points for engine numbers, 476 never had a very high number change point. 668 was the highest I could see, although I didn’t go through the whole lot. I need 10000 + engines of that type to be in the range.
I have another quick question. The UK wouldn’t be classed as a cold climate would it? I have lived in Queensland for 20 years so from my point of view the UK is cold !!
Keep looking I think. Thanks for the info so far guys.
Nick

Hi Chris
Thanks for the links. There is even more of an array of choices than I could possibly have imagined!
Mine should be as follows, although i'm not sure how to recognize the types of crankcase ventilation. No air pump fitted though so that rules out positive ventilation I think?
UK model Originally Single Carb Alternator neg earth, which I thought was a Lucus 11AC so Bf or Kc Originally no PAS Pre engaged Starter (Pf) Rod change manual gearbox (Te) Not sure H/L compression yet. Any ideas of the best way to check? Head has "A" on it if that makes any difference? Not sure if standard ratio gears. Have to look at the box for numbers I think!
That means if I'm right Yd, Bf, Pf, Te the closest I can see is 476 Couldn't find a Yd, Kc, Pf, Te
Keep you posted
Thanks
Nick

Hi
Its good to see there is still a lot of interest in the 1800's.
I will give everybody a bit of background before I ask my question, as a newbie to this forum.
I have owned a UK MK3 for more than 30 years and learned to drive in my dads MK2 sitting on his Knees so you could say I like the car. I was very impressed to meet Bill Price at a car show many years ago and get his signature in his book!! He must have though I was Mad!! I moved to Australia some time ago and my car stayed with Mum and Dad with a view to shipping it down under when I settled in. I also own an Australia MK2 non runner at the moment. Well this is the year (exactly 20 years since the import papers were applied for) the import is going to happen, I hope. The ultimatum from Dad has renewed my interest in the old car!! I have a couple of issues including asbestos removal before it can enter Australia and the engine number is missing due to corrosion.
So to the good old engine number question. I have researched BMC engine numbering a little, which I have to say is interesting as you know!! I would like if possible to get some idea of some real MK3 engine numbers from you guys to see exactly how they fit with the info. Actually MK2 numbers would probably help too. Of course if the good old DVLA had the full number listed on the V5 it wouldn't be a problem!! I have also inquired at the British Motor Heritage Museum, but for my year Austin they only have chassis number and year of manufacture they tell me.
Anyone who has any info concerning engine numbering from a parts list that includes MK3's would be great. There seems to be many of you here with a vast amount of knowledge and your help would be appreciated. Incidentally it is about 95 pounds for a new plate delivered if anyone needs one!
I am only interested in the prefixes not the actual engine number (Privacy) the year of the vehicle and options like PAS, Auto, 1800S or High/Low compression. I am thinking at this stage looking at the MK2 numbering MK3's would be in the range of 301B to 307B or 313F to 317F depending on the options, as these state number 101 on, but this is only a guess from data that only covers MK2's so I am probably way off the track!!
My Car is a 1973 Austin manual with no PAS originally. I think it is a High compression from memory but would have to check.
Thanks in advance for you help
Nick
