A few little things. I started to clean this part up, then I decided to remove it:
The engine had huge potential for modification and the racing versions were developing three times the power of the single carburettor version which resulted in the Imp winning the equivalent of the British Touring Car championship three years in a row: 1970, '71 and '72 In later years people turbocharged them and power outputs of around 170+ bhp were realised
This conflicts with the earlier para which states that engine modifications were limited in scope. So which is it? Also, what is meant by the "equivalent of" the BTCC? Is it the BTCC or is it something else? The turbocharging is not something I've heard of either, can you link to a reputable source?
Also, in the opening para it states that the Imp was "effectively a hatchback" due to its opening rear window. I know what you're trying to say, but I think that's stretching it a bit. A true hatchback is much more than just an opening window. Graham 23:30, 18 January 2006 (UTC)
Added:- "However, in adapting the design to suit modern mass production methods, Rootes had left the engine somewhat more fragile than its Coventry Climax parent, hence any serious tuning must inevitably be accompanied by expensive strengthening modifications such as replacing the cylinder head gasket with gas-filled Wills rings." Which I think sums up the situation.

"The Glaswegian workforce who were all recruited from the shipbuilding industry were also not versed in the intricacies of motor vehicle assembly, and Imp build quality and reliability suffered. They also brought with them their militant left-wing values, and as a result strike action and industrial disputes were a rule rather than an exception." This is hardly the language of an encyclopedia and lacks references. I would suggest making this statement (1) less opinionated and (2) to add references.

The very first paragraph wrongly states: "it was the first mass-produced car with the engine block and cylinder head cast in aluminium." However, various earlier mass-produced cars featured aluminum engine blocks and cylinder heads including famously the 1961-1963 Buick Special and also related but different General Motors (Oldsmobile and Pontiac) models. General Motors built approximately 3/4 million cars with their 215cid (3.5L) aluminum V8 in just three years. One similarity between the General Motors V8 and the Hillman (Climax) four-cylinder is that both used cast-in-place iron cylinder sleeves. Later, Rover purchased design rights to the General Motors "215" engine but manufactured it with pressed-in iron sleeves (years 1967-2004). In the 1970s, Chevrolet's Vega was mass-produced with a linerless aluminum engine block and aluminum cylinder head. -- 2601:1C1:C200:BCF0:244F:4C42:EC3B:5440 ( talk) 05:58, 30 June 2017 (UTC)
At the risk of being accused of using the talk page as a "forum" instead of a place to improve the article, may I point out that that the article doesn't say anywhere what sort of cooling the engine uses. I see a single mention of a "water pump", which suggests a water cooled engine, but at first I was inclined to suspect air cooled, since radiator location is not obvious. I also have changed the claim that the engine "Could be ported and flowed due to the overhead camshaft", because ALL engines can be ported and flowed. Improving the flow of the stock head has nothing to do with whether the valves are actuated by a cam over them or under them. Many argue that an OHC engine allows for better flow inherently by allowing for wider valve angles (without resorting to fancy fixes, a la Hemi engine), but that is totally unrelated to the practice of porting the heads, polishing the air passages, reducing radii, and widening pinch points. These can be done to any engine. But here, I am getting off immediate topic of how to improve the article, and surely the WikiPolice will swoop in any moment now and chastise me for violating policy. Apologies in advance. 70.109.132.119 ( talk) 03:42, 8 March 2018 (UTC)
