Oil Change - When To Stop

[Bidz]

New oil filter on it's way to me, as part of a service before the National.

I've got a 5L can of oil from Wilko's, and how am I meant to know when I've put enough in? Do I just pour it through the cap in the rockerbox cover?

Thanks in advance.

Make sure car is on a flat surface. Buy a plastic measuring jug from supermarket, pour in 6.5 pints or 3.69 litres of oil through the filler cap in the rocker box. Refit filler cap. After ten minutes or so, check oil level on dip stick - should be on full mark. Job done - simples

Use some of the oil to fill the filter before refitting it. Before starting the engine spin it over on the starter motor with the plugs out until the oil pressure light goes out

Hmmm. Oil pressure light? One of those I do not have.

switch it on, on the speedo you will see two lights ,one red the other green marked ign and oil. The one marked OIL (green) is the light that you say you don't have.If you havent ,then re post for further advice.

You MUST have an oil pressure light - and you SHOULD have an oil pressure gauge.

No oil pressure light on Series MM/early Series II. What year is car?
Oil pressure light is not necessarily green, could be amber.

i put about 4 litres in does not matter too much if you put a bit more in by mistake you should ba able to judge it from whats left in the can if its a 5 litre can there should be 20% left in .

Early minors had an oil pressure gauge..
However just like modern cars it wasn't considered 'essential' by the bean counters so later Minors only had a warning light. (and a charging system warning light)

for the oil, you should at least have an oil pressure warning light if nothing else!

As for oil level - add roughly 4 litres & leave for a few minutes, then spin engine with plugs out until oil light goes out, wait again and check level using dip stick and add if required.
Aim to get it at the top of dipstick level mark - that way it's easier to see if/when it looses/uses oil when checking it often during use.

I see. I have one in the speedo, but I don't think it has ever lit up...

It should light when you switch on the Ign - what DO you see then?

Amber light on the right, only.

[bmcecosse]

Well - that's the OIL PRESSURE warning light! But - you should have a 'Not charging' light too -usually RED.

It's behind the IGN lens; is this wrong? There is no red light. The IGN plasti is amber, the OIL is green.

[bmcecosse]

Hmm - well - regardless of colour - you should have TWO lights when switching on... Is there a wire to the oil pressure sensor - on the block -above the starter motor ?

[simmitc]

It sounds like you might have a non-standard speedo - it's VERY unusual for the coloured lenses to be swapped, although quite common for the bulbs to be put in the wrong holder, and also common for bulbs to fail. Start by looking to the rear of the distributor. There should be a pressure switch screwed into the block, with a single wire coming from it. Disconnect the wire and short it to earth. Now turn on the ignition. What lights are showing? Remove the earth connection and re-check for lights. Report back.

For the next test of the ignition warning light, is the car standard dynamo or has it been converted to an alternator? Come to that, is it a standard engine? What year is the car, what size engine?

If you can post a few pics of what happens when we will be able to see what you have
