How can I tell what engine I have in my mini the previous owner has put a different one in and has removed the Engine number plate !

[Ethel]

There are some obvious differences:

 

1275's don't have tappet chest covers and the thermostat housing locates at a different angle on the head. Though you could put a 1275 head on a smaller engine.

 

Different compression ratios were achieved with different piston crowns -  flat or dished...

 

A and A+ blocks have different fitting for the alternator and distributor....

[sledgehammer]

 has removed the Engine number plate !

 

unless he told you he removed it - they do get messed up easily 

 

I've had them rott off / fall off in the past - even thou they are pinned on

 

in addition to ethels post the a series is a smother cast block - the a+ has a ribbed block

 

post a pick so we can have a look

 

Remember red ones are faster

That's a pre A+

A picture would be good, but without an engine number or paperwork, the only way to find out for sure is to pull it apart.

 

Basically from a picture you can tell what the basic engine is, A series or A+, Small or Big Bore but that's about it.

From the photo it is a pre-A+ with a Verto clutch. The distributor aperture is large and the block has no external ribs.

Without a photo of the back of the block it is hard to tell whether it is a 998 or 1275. If it has two cam chest covers on the back, each about 4" x 7" with a centre bolt, then it is a 998. If the back of the block is solid it is a 1275 block.

[Ivor Badger]

its a 998/1098 head. Looking at the starter = possible metro

Sorry, didn't realise that the photo was the actual engine.... thought that was just and example photo...

 

Cooperman, you should know better.... slapped wrist ;)

Two core plugs in the block above the transfer case and it's an A series, it must be a solid wall big bore, other wise it'd have 1 core plug.

 

It's a right Heinz 57 of an engine... Metro starter motor, A series block, A+ head, Verto clutch

Numbers on block and gearbox  do these apply to anything?

 

[Spider]

Working from the Freeze Plug type, size and number of them the block is a Pre-A+ 1275, no question.

 

Working from the Thermostat Housing orientation, the Head is also 1275.
