revilla Posted May 21, 2014 Share Posted May 21, 2014 The bank account drops to zero? Oh no, that's the second sign, if you don't notice the first Link to comment Share on other sites More sharing options...
Klunk Posted May 21, 2014 Share Posted May 21, 2014 Probably something vague like the engine warning light comes on! 😔 At a guess, the first thing is probably the coolant temp rising followed by cam/lifter rattle, bottom end knock and then your engine leaving the car in pieces via the block/sump Link to comment Share on other sites More sharing options...
andy_h Posted May 21, 2014 Share Posted May 21, 2014 I'd go for gauge or warning light. Then temp rising Possible oil slick at same time. Link to comment Share on other sites More sharing options...

revilla Posted May 21, 2014 Share Posted May 21, 2014 "engine oil pressure failure" sounds like unusual wording ... are you sure you didn't mean to put "engine oil pressure GAUGE failure" ... in which case people might go for rather different answers?

Roger King Posted May 21, 2014 Share Posted May 21, 2014 What a stupid question! The answer could be any number of things from rising water temperature to loss of power depending on the circumstances and the cause of the fault. Link to comment Share on other sites More sharing options...
John Vine Posted May 21, 2014 Share Posted May 21, 2014 Quoting Roger King: What a stupid question! The answer could be any number of things from rising water temperature to loss of power depending on the circumstances and the cause of the fault.Indeed. Maybe the answer will prove to be as stupid. I'm always suspicious when an examiner poses a question containing a phrase like "engine oil pressure failure", where three out of the four nouns are modifiers. That's a recipe for ambiguity. In the technical authoring world, that usage is often described as "noun modifier pile-up syndrome". JV Link to comment Share on other sites More sharing options...
Guest Posted May 21, 2014 Share Posted May 21, 2014 I'll say low oil level on the dipstick, noisy oil pump or difficulty starting engine/appearance of flat battery. Bob Link to comment Share on other sites More sharing options...

Piers Rendell Posted May 21, 2014 Share Posted May 21, 2014 By analyising the oil , you will see increases in bearing materials and other wear metals. Piers R30oKWK Link to comment Share on other sites More sharing options...
malcolm1sim Posted May 21, 2014 Share Posted May 21, 2014 At the first corner following failure you hit the wall very hard, backwards. Link to comment Share on other sites More sharing options...
Birkin S3 ZA. Posted May 21, 2014 Author Share Posted May 21, 2014 Well SM25 is the closest 😶🌫️ The answer was bearing failure/ engine knock, out of 25 students none of us got it right. There reasoning was the white metal coating is designed to melt with oil starvation leading to engine knock, then the crank can be saved and the bearings replaced. I think the person who wrote the question spent his days casting and scraping white metal bearings, the question and answer would then be relevant then but not in 1977.

Chris The first sign is bearing failure. Brilliant - that's useful. Full engine rebuild / replacement required. I would have thought low oil level or leaking oil would have been a better *FIRST* sign. Jez Link to comment Share on other sites More sharing options...
