Most mini's will have some type of oil leak somewhere , it's part of them and the age of components . How big a leak is the real question , a spot or two per day or a dinner plate sized puddle per day ? The first accesory most peoplembuy for their mini is an oil drip tray for the garage floor . If it ever stops leaking oil then you know it needs topping up



Ic. So even the best done up old minis will have the same problem, heh? ok. The leak is like the size of a 5 cent coin for the spot and another smaller than it. So there are actually 2 places. And those 2 spots on the floor are always wet.

Well, I don't know how many drops it leaks out from the same points. But I think it is contiunously dropping (though I can't see it cus it drops slow and just haven't got the patience to sit there and watch them all the time especially the mosquitoes are all around you cus they will most likely attack you when you are still). However, I can see the drop is hanging there from the gearbox and when I touch it it's all greasy and wet.

There was once when I make a sharper downwards turn and the engine just went out (Note: the mini was just fuelled up with 98 Octane petrol(V-Power)). So I guess it might be the engine oil? But then I see the oil gauge, it's right at the 50% mark, I then take the dip-stick out and saw that it's actaully @ MIN (Note I only drove it 5 times - 20min each time). The level is just right at the middle of the "M" letter. So I bought some motor oil and open the rocker cap, pour almost half of the 8L bottle in. But there seems no much difference in the oil Guage and I use a torch and look inside where I pour the oil and trying to see what happens after I keep filling it - well, not much difference, maybe 1-2 mm rise in height. Probably something wrong with the reading? If so, where could I bring it to fix it (i.e the oil gauge detection).

Are you serious about the amount of oil you put in or is this a joke ? The mini will hold around 4 1/2 to 5 litres of oil (not sure on an auto box , someone help me out here ) , if it's showing on the min mark of the dipstick it will only need about 250 to 500 ml's of oil to bring it up to the max mark . Where does the oil level sit on the dipstick now ? If you did add half a big bottle of oil to the engine when it was on the min mark DO NOT DRIVE IT till you get someone who knows what they are doing to look at it and drain some oil .

sports850:

Its now a bit above the MAX word. I am not exactly sure now, have to go to my gf's garage and see next week.

I dunno if the engine of a manual mini shares oil with it's gears. But my auto does. That maybe why it's getting so much oil but not much of a rise in the oil level?? (either in the gauge reading nor the inside)


But the way, just out of curiosity, how do you change oil? easy but messy? keke

Ben

The manual gearbox shares the engine oil the same as the auto does . Someone else here with more experience with auto's will be able to tell you the total capacity of the auto motor/box , I'd have it in a book somewhere but haven't got time to search at present . Make sure the level on the dipstick is no more than1/4" (5 or so mm) above the max mark at the most .

Speaking of leaks I think my sump lug is loose even though it rock solid tight (within reason of course) ... I cant remember if theres a washer as well as the plug... or should i invest in a new plug all together??

A new washer to start with would be good , theoretically you're supposed to replace them every now and then anyway .

Ben that is a lot of oil you have put in..when you check the oil level are you sure you pressed it all the way down..DON"T over fill your oil..it can cause oil leaks of you could be driving along and become the Bat Mobile :shock:

what is a plug and where is it?
Is it somthing you could pull it and where the oil will drain out from?

Where is the washer and what's it's purpose? is it something which sits between the plug and the gerabox?

What's the sump lug?

I hope you will tolerate my my stupid questions since I am a beginner. :roll:


I just went to check the bottle I bought over the road. It's 4 litres. That means I have poured almost 2Litres in there. I am a dumb A?? man. I will check the dip stick next week, hope it will not go over the max line. If so, crap!

Yes, pushed it all the way down and keep wiping it and dip it a few times.

Ben we all started new here and asked plenty of questions...so ask away.
The Sump Plug (Lug :lol: ) is on the drivers side on the on the bottom side of the gear box. I can't tell you what size the socket you will need as my wife just went up to the shops in Morris.
You will have a copper washes on this hex sump plug. Most of the time it also has a Magnet on the end to collect bits and piece of Metal (Swoth) and should also be clean off also
If your just going to drain a little oil out don't worry about the swoth

Haha, Bat mobile, what about Bat man (would be the driver heh?)?

The mess can be cleaned up, but what really of concern is if it will do harm to the engine and the box.

Alrite, so the sump plug is where the oil comes out if you wanna change the oil.

shops in Morris? a shop for getting mini stuffs? cool where is it?


I guess the socket is where the plug goes into?

Why would you need a magnet for? Is it to attract the metal residuals in the oil to the bottom so that it will all be drained out when you pull the plug out?

Could I use an extractor to take some excessive oil through the cap at the top instead using the plug?

Yep Correct

Nope thats what my wife called our Mini..Its like calling a Cat "Cat"

If you want to drain the oil from the engine Yes :wink:

As you use your engine Specialy as the Box and Engine share the Same oil you will have Swoth (metal fillings) going all around the engine and this helps to stop this

Could I use an extractor to take some excessive oil through the cap at the top instead using the plug?
Nope...when you poor Oil in via the rocker cover it runs down the bottom of the Engine/Gear Box via holes in the head and the block


hope that helps

That's really helpful. Thanks.

But just another thing. If they all went down, then why could I see the oil level there inside the rocker after I open the rocker cap (both before and after filled)?

Also any precaustion/sugesstion if I were to drain some oil out? tools, etc?

two reasons....after pooring oil into the rocker cover oil will always settle in thier..also..oil does come up from the bottom of the motor into the rocker cover area/top of the head and around the engine....
2nd hope you didn't fill it that much then :?

With a manual Mini it's normal to check the oil level when cold.
This is NOT CORRECT for an automatic.

When cold, some oil always drains out of the torque converter back into the gearbox, so it will (and should) look over-full.
Automatics should be checked when warm. Stop the engine, wait 30-40 secs, check level on dipstick. :wink:
