Coucou,
Un doute m’habite :
Pour vérif de mon niveau d’huile sur mon 1400K, la tirette n’a qu’une marque.
Cette dernière matérialise le niveau haut ou bas ?

D'après ce que j'ai compris en regroupant plusieurs avis, il y a eu 2 types de jauges sur les Rover K de nos Cat. L'ancienne (la tienne apparemment) avait une échancrure sur le côté qui marquait le niveau haut, moteur arrêté.Wet Sump
Run engine until oil is warm. Leave idling for 2 minutes on level ground.
While still running, dip using a sharp action to get a clean measurement. You can shutdown first as long as you dip immediately, but if you leave it for 30 seconds the oil drains from the head raising the oil level. If you cannot read the oil level on the dipstick because the oil is very clean, press the dipstick against a clean piece of paper towel and the oil will show up very clearly on the paper.
There have been two dipticks. The original Rover one was all yellow plastic and was modified by Caterham with a notch cut on it; the oil should be at the level of the notch. The new caterham specific dipstick has a yellow plastic hatched section on the end of a metal dipstick; the oil level should be at the top of the hatched section when measured in this way. Please note that the oil level is much higher than Rover ever intended for the engine and the oil level is very close to the opening of the dipstick tube in the sump. If you overfill the engine it may not show up as being any higher on the dipstick, so it is more important that you check frequently and add small mounts of oil; thinking you can get away with throwing in some extra oil to keep you going between less frequent checks is not good for your engine. The engine is non-standard on account of being fitted with a shallow sump.
La seconde avec un treillis, un niveau min et un max, moteur tournant.
Mais j'attend la confirmation des pros pour ce qui est du moteur tournant/arrêté.

Checking the Oil Level
Wet Sump

The engine is non-standard on account of being fitted with a shallow sump.
Rationale (wet sump)
The original caterham instructions were to dip the engine at standstill. When the Apollo tank started coming into use, it was noticed that the oil in the sump was very low when the car was running - it is this oil level that is doing the important job of keeping the pickup immersed, so there was obviously more variation between running and resting oil levels with an Apollo tank equipped car than without. This was because the Apollo tank was draining back when the engine was not running giving a false high oil level reading.
It was also found that Rover fitted VVC engines with a different dipstick due to the amount of oil the VVC head retains. Caterham decided that, with all the different combinations, the simplest way was to check oil level with the engine running
Dry Sump
There have been two variations of Caterham dry sump system for the K. The original used a purple scavenge pump with a large pulley. The system introduced for the Superlight racers used a gold coloured pump running a smaller pulley. Both systems used a special bellhousing containing an oil tank, but the later gold pump system introduced a de-aeration tower bolted to the top of the bellhousing tank (AKA "conning tower" with a different mode of operation to the Apollo tank). The methods of checking oil levels are slightly different between the two dry sump setups. The R500 system uses the same gold pump/conning tower system but uses magnesium castings; the R500 system is sometimes fitted with a small Apollo tank.
The best practice is to establish a correct oil level by overfilling the system slightly so that some oil is vented to the catch tank after going for a drive with mixed amounts of high rev use, idling and cornering. Once the oil level has settled so that no more is being vented to the catch tank when driven, the oil level is by definition at its optimum level. It makes sense to measure the oil level physically with a dipstick once this correct level has been established so that you can replicate the oil level without unnecessarily wasting new oil by venting it straight into the catch tank.
The dipstick provided in the conning tower installation is generally useless (it tends to fall out of its cap after a few months use and it is very difficult to read the clean oil level on the green plastic.) In order to get reliable dipstick readings you need to establish a routine. Easiest is to follow a similar procedure as for wet sump engines: run the engine until it is warm, with warm oil (above 50 degrees centigrade); allow the engine to idle for 2 minutes on level ground; shut down the engine and immediately dip the bellhousing tank using a long dipstick that reaches right to the bottom of the tank (most reliable method), taking care that the dipstick clears the oil pickup and does actually reach the bottom of the tank.
On a gold pump/conning tower equipped engine, the correct oil level is usually between 10 and 11 inches from the bottom of the tank. On a purple pump/non-conning tower equipped engine, the oil level is usually an inch or so below the baffle plate you see when you remove the cap on top of the bellhousing tank. No special measures need to be applied for an engine fitted with an Apollo tank in addition to a dry sump system.
Rationale (dry sump)
The scavenge pump always evacuates more volume from the engine than is being pumped in by the pressure pump. It often pumps a mixture of oil and fumes, but if the scavenge pickup is immersed in oil it will quickly pump the sump dry to the point where it is sucking a mixture of oil and fumes again. After idling with hot oil for a couple of minutes the greatest amount of oil will have been pumped into the bellhousing tank; the hot oil has the greatest chance to drain quickly from the head under the action of gravity down to the pickup. After shutting down, there will be a slow seepage of oil back from the tank into the engine but it gives plenty of time to get a reliable dipstick reading of the oil level in the bellhousing tank.

- tout pareil sauf les marques en partie basse de la gauge. me voila rassuréPatrack7 a écrit :Oh qu'elle est belle ma jauge !
J'ai un petit doute.J'ai fait récemment ma vidange (huile + filtre + mousse), et j'ai remis exactement la quantité d'huile préconisée par Caterham. A chaud, moteur tournant, j'arrive pile poil au niveau 1. Je suis sur le 2 à l'arrêt, moteur froid.
mais y a t il une limite basse que l'on pourrai gradué?

Il faut être au repère 2 à chaud, car à froid moteur arrêté, une partie de l'huile redescend et complète le niveau, donc le niveau 1 correspond au niveau mini en quelque sorte. C'est mal foutu le reover, faut le pencher pour qu'il rentrePatrack7 a écrit :Oh qu'elle est belle ma jauge !

Mais c'est bizarre car j'ai mis exactement 4 litres d'huile, ce que préconise Caterham. Il faudrait mettre 4,5 L. 
T'as 4.0 L d'huile Patrick, et 0.5 dans le filtre... Raison peut-être pour ton niveau plus bas. Perso, je vais essayer de me trouver une bonne vieille jauge métal, plus longue, que je couperai et dont je ferai les encoches, car le plastique, pour la jauge, c'est pas fantastique...
