How are the cylinder banks assigned? Front bank=left? Rear bank=right? This plays havoc with my dyslexia. Thanks
I suspect if you are facing the front of the motor (looking at it from the passenger side of the car), the right bank would be towards the front, left towards the rear.
View is from the flywheel end. Rear bank is right and fwd bank left. Dx is right and Sx is left. I use Doctor DR to remember right. Image Unavailable, Please Login Image Unavailable, Please Login
But the crank has 2 ends. So left and right depends which end of the crank you're looking at. Same issue with saying "left front fender". Oh? Looking from the front it's that one, looking from the back it's the other one. Left in this case has no clear meaning - it's dependent on the viewpoint.
This is correct, and in relation to the car, things like LH guard or RH guard are always taken from the viewpoint of sitting in the drivers seat Sent from my iPhone using FerrariChat
Parts book is clear. Dx is right and Sx is left. View frim flywheel end. Image Unavailable, Please Login
The heads are marked S and D. It's in Italian so S is sinistra for left and D is (I forget) whatever the word is for right. Also, pretty universal that left and right are as viewed from the driver's seat which doesn't work for a transverse layout but imagine if they were to use the only other option, you get the point. And I guess I should add that I don't mean turning around and looking backwards at the engine. See, it's complicated. Not a dumb question at all lol.
The convention selected made perfect (and more easy to understand) sense when they were only making front-engine, longitudinally-mounted models in the 40s and 50s with the crank snout forward . There's usually a (very useful for a bunch of stuff IMO) unambiguous figure in the transverse-mounted model OMs showing that they kept the same convention: Image Unavailable, Please Login
Another way to remember is to pretend you’re riding your engine, like a horse. Crank pulley’s in front of you and clutch is behind you. To your right is the right bank, to your left is the left. So in a 308 the right bank is toward the back of the car. In a 911 and a Countach, the right bank is on the left (US driver’s) side of the car. Just ride your engine!
Steve, What manual did you get your photo from? I have the Mondial 8 Quatrovalve shop manual and the firing order is wrong. 3 and 5 are reversed. After I built my engine it didn't run very well until I figured that out.
It's probably from the 1978-9 US 308 B/S OM (but I'm not sure). Virtually every Ferrari V-engine has alternate bank firing so 3 could never follow 1.
Sinistra has the same root as the English word "sinister." Those left-handed people are untrustworthy. It's also a good way to remember that S is left.
Absolutely, “sinister” has the same root than “senestra”: left is negative; and “destra”, which is “dextre” in French, for instance has given “dexterous” in English: skilful, master: right is positive. The romans were superstitious and, for many different reasons, “left” (= senestra) was associated with evil, or wrong: when a flight of birds was coming from the left, it was a bad omen. French being based mainly on latin (but also, in a lesser part, on Greek), the latin words for right and left (Destra / Senestra) were transfered almost as such in ancien french: “Dextre” and “Senestre”; with the passing of the time, they were replaced by “droite” et “gauche”. These are not used anymore, but their old meaning remains: right (droite) (ex dextre) has positive implication (“dextérité”: very skilful or…dexterous, in english; handy. “droit”: trustworthy; etc…) gauche, which has superseeded “senestre”, means unhandy, unwieldly: for instance “un homme gauche”: someone who is akward, clumsy.

Hello all, Spanish it's pretty much the same, as Spanish is a latin language. Derecha is right izquierda is left, plus they also have "siniestra" which means evil. I guess English is somewhat alike, for example; when you say "do things right" is just the same as saying "do things correct" or woke up with my left foot means starting a bad day. Just a comment. John.
To further confuse things - while left and right, as far as engines go, are pretty much universal so is the use of bank 1 and bank 2 where left is bank 1 yet Ferrari starts numbering their cylinders at the front of bank 2 and goes around in a U to the front of bank 1. So much for universal conventions.
