Morris Minor Owners Club

Can't seem to upload pics. I've been given an engine,Gold seal replacment.Can't make out the size 1098 - 950 etc. Came with a relpacment ( Gold ) ribbed gear box. Looks like the tab on the side with the engine size has been removed. Engine number 8G163 R M4474, with AD added below. Any ideas ? [frame][/frame]

We do really need piccys - they're probably too big. Open them in paint and resize them there to about 300 pixels less, and save them again in your Pictures file. Then upload again.

Hope this helps[frame][/frame]

I'd hazard a guess at 948...

Note the oil filler cap is the wrong one.

Be careful with that metal vac pipe!

It is probably a 1098 engine. Look under the rocker cover - if it is a 12G202 head then that confirms 1098...

On the exhaust side of the engine - you may see 950 or 1100 cast into the block - that would give you a clue and the oil filler cap would appear to be a radiator cap!! The head has a temp sender unit tapping just under the thermostat housing so would suggest a 1098. Vac pipe is going the wrong way though - would normally go towards the thermostat and on to the carb.???

1100 was never cast in the block. It's just possible (but unlikely) that it is a 848 engine - hence the need to check the head casting number. And whatever you do - preserve that rocker cover with the BMC sticker showing!!!!

What backplate and clutch are fitted?
950 would be cast in the block,1098 would have 1100 tag

It 'looks' like the thick 1098 backplate - but the 848 probably used that backplate too...

Looks to have a solid casting for the mechanical fuel pump also - which to me signifies an 1100 block..
Yes, or possibly an 850

This type of oil filler cap was widely used on Triumphs, Hillmans and Vauxhalls of the period. What it is doing on a Minor engine is anybody's guess.

Thanks everyone, just pushed it into the garage until my next day off,more investigations then.
Nothing on the block, just a missing tab. Heater tap, (or hole for it) on the rear of the block, has a blanking plate.
If it were an 803 ? would it not have a screw on oil filter ? I think the rad cap, on top of the rocker box, was an attempt to keep dirt out etc. The engine was given to me from a neighbour, he was winding his late Fathers estate up. Think I mentioned, a ribbed, gold, gear box came with the engine. Would a 1098 box work with a 950 engine ? ?
Anyway, get your Ski's on, looks like we are in for a bit of snow over the weekend.

Dear Old SLM, now havin a well earned rest, Thirty years in a Scottish Forest, and the engine still turns over !
Whoops, can't post pics again.

A ribbed box will 'fit', needs an 1100 style clutch and backplate at least to fit. I would say assume it is an 1100, the chances of BMC putting a 950 with an 1100 gearbox is remote.

Thanks Chesney.

OK folks, got there in the end. Far better with plugs and points. Have a good weekend.

It's certainly not an 803....

Thanks BMCecosse.
