MG Midget and Sprite Technical - Engine ID

Can anyone help.
I've the possibility of a bare engine 8G 162 ES58***, but I'm unsure as to what size it actually is.

Is it a 1098 ?

Any websites that I can use to check please ?
Graham


Hi Graham,

I found some info that is pasted below on the following site

http://mgaguru.com/mgtech/engine/be100.htm

pre-1956 reconditioned engines were prefixed 8G, only when the Gold Seal Exchange engine arrived, was there any difference). On a late note, BHM 1109 turns out to be a Marina 1.8-GT-Special MK 2 exchange engine (Austin Marina in the USA).

Austin A35 van (optional)848cc 8G ( post 1962 all GPO.)

GOLD SEAL EXCHANGE ENGINES

BMC like many firms did an exchange scheme for worn engines, one was the Gold Seal engine, a complete engine ready to fit and painted gold in colour. The other was the Silver Seal exchange engine, basically a short-block for the owner/garage to fit the old head,sump, and ancillories onto.

Both used a similar system of engine numbering, the original number being struck off.
Initially all engines in the scheme were prefixed 8G, soon a better system followed:

48G is a 'B' series Gold Seal reconditioned unit. The 'A' series was 8G, and the 'C' series 68G. (** All'A' series engines were prefixed 8G,- 803cc, 848cc, 948cc, 1098cc, 1275cc.
'B' series were prefixed 48G,- 1200cc, 1489cc, 1588cc, 1622cc, 1798cc.
'C' series were prefixed 68G,- 2639cc, 2912cc.

The code after was to do with rebore/regrind sizes and a job number.

There are a number of identifying features on various A-series engines. Some of them have the capacity cast into the side of the block, helpfully.

The type of cylinder head can help with identification, assuming that there is one fitted and that it is the correct type for the engine. If there isn't one fitted, it's simply a matter of measuring bore and stroke.

The backplates also differ between engines, although you are again relying on it being the correct one.

Sumps also differ between some models and 1275s have no tappet chest covers, so are easy to spot.

Moss list it as a recon 1098 Morris Minor engine.
