Circa 1290: The construct was oil + -er.  Oil was from the Middle English olyer, oyller & oyellere (the later alternative spellings included oylle, olie, oli, eoli, eoyle, olige, oyll, uile, oile & oyl.  Oyler was from the Anglo-Norman olie and the Old French oile, from the Latin oleum (olive oil), from the Ancient Greek ἔλαιον (élaion) (olive oil).  The –er suffix was from the Middle English –er & -ere, from the Old English -ere, from the Proto-Germanic -ārijaz, thought most likely to have been borrowed from the Latin –ārius where, as a suffix, it was used to form adjectives from nouns or numerals.  In English, the –er suffix, when added to a verb, created an agent noun: the person or thing that doing the action indicated by the root verb.   The use in English was reinforced by the synonymous but unrelated Old French –or & -eor (the Anglo-Norman variant -our), from the Latin -ātor & -tor, from the primitive Indo-European -tōr.  When appended to a noun, it created the noun denoting an occupation or describing the person whose occupation is the noun.  The meaning “an appliance for distributing oil in machines" was in use by 1861 and was adopted by the British Admiralty in 1916 to describe "navy vessels carrying oil for use by other ships"; although such vessels had been in use for some years, the Royal Navy having begun the conversion from coal to oil a decade earlier, by 1911 only the submarine fleet ran exclusive on oil and coal (sometimes sprayed with oil) still fuelled most of the navy’s vessels.

Evolution of the Ford 427 side-oiler

The side valve (usually called “the flathead”, an allusion to the almost flat plate covering the combustion chambers) Ford V8 of 1932 is remembered for its vices as well as the many things which made it one of the great engines of the mid-century.  In the 1930s, those vices could be both forgiven and worked-around but by 1953, it was still in production and outdated (though in overseas production it would continue, in French Simca cars until 1961, in Brazilian Fords until 1964 and remarkably, until 1990 in the Simca Unic Marmon Bocquet military truck.  For 1954, Ford responded to the modern overhead valve (OHV) V8s others had introduced with the debut of two new engines, essentially (by the standards of the time) small and big block versions of the same design.  Known as the Y-Blocks because of the shape of the castings, they were sturdy pieces of machinery and addressed many of the problems identified in the flathead over two decades of production but neither was suited to the evolutionary path the American automobile would follow during the 1950s.

That path was not one which anyone in Detroit was likely to foresee in the late 1940s when the design work on the Y-Blocks began but by 1954, it was at least competitive with the competition.  However, in 1955, Chevrolet introduced their small-block V8 which was light, compact and free-breathing, not something which could be said of the Y-Blocks and more importantly, the design afforded a potential for development which would play out over decades.  By contrast, the Y-Blocks’ potential in both capacity and power output soon plateaued and Ford was forced to resort to exotic solutions like supercharging, something not practical for low-cost mass-manufacturing.  Ford’s solution was not one new V8 but three.  All released during 1958, the SD (Super Duty, a large, low revving truck engine), the MEL (a big block for what were now very large Lincolns and Mercurys) and the FE (thought at the time a big-block but subsequently listed by pedants as a mid-block because later castings would out-weigh it by so much).  The durable SD would remain in the catalogue until 1980, its demise prompted only by the implications of the second oil-shock in 1979, the sole complaint about it being its prodigious thirst.  The MEL would last a decade, early attempts to use it on the race-tracks abandoned because of the penalty imposed by excessive weight although it did enjoy some success in powerboat racing where it’s capacity to run reliably at full throttle for sustained periods was much admired.

By their bolts they shall be known.  By convention a "four bolter" was one with the four all into the boss while in a "cross bolter" two were in the boss and two into the block.  "Six bolters" (with four in the boss, two in the block) are now common.

Although it would quickly earn a stellar reputation which endures to this day, Ford’s FE V8 engine didn’t enjoy a wholly auspicious start, associated as it was with the ill-fated Edsel (FE really did stand for “Ford-Edsel” despite some post-debacle attempts to suggest “Ford Engine” (the contemporary MEL stood for Mercury-Edsel-Lincoln)).  However, whatever the problems of the Edsel, the use of the FE is some was not one.  Offered initially in several displacements, the most produced in the 1960s would be the 352 & 390 cubic inch (5.8 & 6.5 litre) versions, both of which briefly were offered in high-performance versions until the decision was taken to develop such engines as a separate FE branch, the first fruit of which was the 406 (6.6 litre) which debuted in 1962.  The 406 had performed well on Ford’s test-rigs, its output slightly exceeding the engineers’ projections and when installed in the new, slippery bodies offered that year, proved fast on the track.  The power and speed however came at the cost of reliability and the increasing speeds on the circuits had exposed weaknesses in the bottom-end, the main bearing caps “walking” when the vibrations reached a certain resonance.  The solution was to “cross-bolt” the caps; an addition two securing bolts (installed sideways through the block) per cap augmenting the pairs mounted in the conventional vertical position.  This approach, still widely used to this day, proved successful and was carried over when in 1963 the FE was further enlarged to 425 cubic inches (7.0 litre), Ford labelling the new mill the 427 to align it with the displacement limit used by both NASCAR (National Association for Stock Car Auto Racing) and the FIA (Fédération Internationale de l'Automobile (the International Automobile Federation and world sport’s dopiest regulatory body)).  However, greater capacity meant more power, higher speeds and increased heat and the 427 began to also to suffer, the higher internal pressures meaning lubrication to the now cross-bolted main bearings had become marginal.  Ford’s solution was to reverse the priority with which oil was delivered.  The original design (subsequently known as the “top-oiler”) lubricated first the valve-train at the top of the engine, then the main bearings which supported the crankshaft.  The new process reversed this order and the design became known as the side-oiler.

Introduced in 1965, the side-oiling proved the final solution and the 427 became a paragon of reliability, powering even the Le Mans 24 hour winning GT40s in 1966 & 1967.  Today the 427 is perhaps best remembered as the power-plant in the 427 AC Shelby Cobra (although some of those actually used the rather more tame FE 428) but in those happy days when one could tick a box and have what was essentially a racing engine installed in a road car, it was available also in full-sized machines (the Galaxie), intermediates (the Fairlane) and, at the tail-end of production, a few (by then somewhat toned down) were even put in the Cougar, Mercury’s Mustang-based take on the pony-car.  By then however, the side-oiler’s days were numbered because not only was it noisy, apt to be cantankerous and a bit of an oil-burner, the complex lubrication and cross bolting made it quite expensive to build, added to which the big bore was at close to the limit the FE block could accommodate so during the manufacturing process, even a slight shift in the casting cores meant a scrapped block.  Thus the attraction for most purposes of the 428 with its smaller bore.

The side oiler also provided the basis for one engine which wasn’t quite mythical because quite a few were built but remains mysterious because nobody seems quite sure how many but the consensus is it was somewhere in three figures.  This was the 427 SOHC (single overhead camshaft (the “sock” in the slang of some)) which for all sorts of reasons never made it onto the circuits for which it was intended nor into even one road car, despite the wishes of many.  Popularly known as “the cammer”, even some sixty years on there’s still a mystique surrounding the cammer and if one can’t find an original for sale (one sold at auction in 2021 for US$60,000), from a variety of manufacturers it’s possible still to buy all the bits and pieces needed to build one.

An oiler: To remove what she describes as "crazy mascara", Lindsay Lohan posted on Instagram details of her technique which is to apply organic coconut oil to the whole face, rubbing in well.  Then she uses a damp towel to remove the oil which takes with it the dissolved mascara.  It actually removes most forms of makeup and has the added benefit of leaving the skin clean and soft.
