.... without engine numbers or the ability to take it to bits!!!
You might get some conflicting information here AND consider that it might have been repainted
METAL may be a better guide than PAINT!!!!
#1 From Stuart Carter
I've just measured
our 1275 and 1098 engines (1098 should
be the same as 998), and the results are - on the clutch
end of the block, you'll find:
1098: 1 core plug @ approx 40mm diameter
1275: 2 core plugs @ approx 36mm diameter
#2 From Scott Beavis
A+ : Dizzy fork
clamp, bolt into block
A : Dizzy ring clamp, bolt part of clamp
998 : Tappet chest covers on back of block
1275 : Breather above clutch, thermostat housing has two bolts at
front, one at back
Factory engine block colours (added to satiate Scotts desire for a result when searching for....)
A 850: black
A 998: red
A 1275: blue
A+ 998: yellow
A+ 1275: red
#3 from John Middleton
Standard metro 1275 A+ blocks also red.
#4 from Colin Sutton:
Nahhhh. It's all to do with age.
Pre-Mark III - all green.
Mark III - end > of A series - all black.
A+ all yellowy gold, except MG 1275 - red.
#5 from Gary Carr
easy ways to tell are that a 1275 will have a breather by the
earth strap a 998 will have tappet inspetion covers on the
back of the block there are a few more but i cant remember them ;-p
#6 from FB & Gareth Jones
dipstick in a metal tube = A series
dipstick fitting ok into the engine without a tube = A+
water pump linked to head via a little rubber bypass = NOT METRO
electronic distributor = unlikely to be A series
look for ROCKER TAPPET CHEST COVERS ON BACK OF BLOCK
If they're there it's a small bore block (or an S) if they're
absent it's a 1275.
If it is an A+ then tappet covers = 998, no tappet covers
because they only did A+ in those two capacities.
#7 from Don Davis
Early 1275s (before 1970 or so) had tappet chest covers.
In the USA, a mini with a 1275 w/o tappet covers is pretty good evidence that a car is not a real Cooper S, but an 850 with an Austin 1300 motor
#8 from Paul
I Thought just the high output 1275 + where red,
as in vanden plas HLS and the MG Metro. (All too confusing.)
#9 From John Small
For all Australian produced Minis,
the engine number is stamped directly
into the block, rather than on a plate that is
reiveted on and can be removed/lost.
Colours were simple too: Round-Nosed models - all
capacities were green, Clubmans - all
capacities were black, except Clubman GT which was
green (it was a Mk2 Cooper S Spec after
