HTML-код
- Опубликовано: 12 сен 2019
- ► Even though it may be tucked away out of sight, your vacuum pump on the N14 engine is an essential part of keeping your engine running healthy. A failed vacuum pump can seize up and cause carnage within the engine block, as shown here by our own resident MINI addict and digital content producer, Ben Marouski. We're back with another video to take you through some of the failure symptoms, diagnosis tips and overall highlights of this MINI N14 Vacuum Pump replacement.

Thank you! I keep my oil just below the max line. I went through yesterday and replaced all of the gaskets on my pump, making sure everything was hand tight and my car is a lot happier. 😅
Exceptionally helpful video. Extremely grateful for the info. Thanks.
Very welcome!
Very good comprehensive video. Thx!
Great video , is water pump replacement ok to do yourself?
I like the video but you scared me and shared alot ,,,thank you..I am In South Africa
I been going nuts looking for this oil leak..glad this video helped before starving the vac pump.. Its been driving me insane lol thanks guys 🙏
Happy to help RICH! Let us know if you ever need any other parts as we continue to build our MINI catalog. Hope your MINI is up running soon.
@@fcpeuro just one quick question.. What is this part on the n12 cylinder head?..its on the driver side, rear.. 3 torx bolts and one connector.. Thought i was a hpfp but n12 doesn't have it. Mine was leaking some from there also..took it out to clean and reseal

@@fcpeuro it was the actuator !! Awesome.. There was a leak there.. It was tough to take out and reinstall
Dude...that was 6:10 of gold...Thank you
Thank YOU for watching!
Excellent heads up ! many thanks...Seems like a complete design fault or made to fail, Planned Obsolescence ? surly they could of been design not to do that as a fail safe?. looks like its just best to change it every couple of years and watch your oil level like an obsession!
You're welcome, Christopher, happy we can help! As you mentioned keeping an eye on your oil level and basic maintenance is great place to start. It doesnt help that the pump naturally ticks so its a little bit like the boy who cried wolf of car parts.
great vid !!!
glad you liked it!
Dang bro I’m about to order mine now!!!
Hi, if the vacuum pump not working properly, is it possible as a strong suction from the engine oil cup? Thank you so much.
Excellent video rhat
has it got any return valve to stop engine oil from coming off to the booster in case the one in booster failed ,I have one here gave me aheadache to find out how come the oil in booster , the brake booster literally filled with oil , I would assume this happening during engine shutdown as that vacuum on booster will suck any oil in pump if it has not got valve at the outlet where vacuum hose connected to it , can you elaborate in this please
Great video, I have a n12 and my vacuum pump ticks on idle, I thought I was the timing chain but it seems to be coming from the vacuum pump.
Glad you enjoyed the video! The timing chain is also known for the death rattle, but direct injection engines in general can have a bunch of "ticks" coming from them. The MINI engines it can be the hydraulic lifters, the injectors, the vacuum pump etc. all make ticking noises unfortunately.
Buying after Mini Doctor on Instagram spoke of saving your engine, RUclips search and found this. Thanks!
Geoff glad we came up when looking - As MINI owner's ourselves we know the pain points of N14 life unfortunately. Happy we are here to help!
@@fcpeuro Yeah was a great video so thanks. All swapped out yesterday. Found the old one had a leak on it too as it had passed the o-ring so another good reason it got swapped out!
@@geoffclement6138 no better feeling than finding a smoking gun to your issue and remedying it with something fresh and new! Glad it worked out for you Geoff!
Can you just hook up the vacuumpump and monitor the gage reading?
Are these failures also common for the BMW N13 engines?
I have an R55 non turbo that will not stay running and will not start without pushing the gas and holding the gas to keep it running. If I hold it at 2000 the tac bumps to 2200 and back and when I let off the petal it dies.
Can it cause code exhaust camshaft installation faulty for bmw n13 engine?
Hello !
What is the vacuum pressure this pump must do ..?
Can a vacume pump cause low oil
Pressure?
damn it.. same problem like mine.. new engine coming up.
Ben is on his 4th N14.... old broken Vacuum pumps claimed 2 alone so far 🙄 Atleast its an easy install and affordable part!
this catastrophic failure just happened to my JCW, finished rebuilding the engine and runs fine now. my car has only 30,000km from 2010, I barely use it but this happened, any tips to prevent this from happening again in the future?
how often did you change your oil? If you didn’t drive it frequently, your schedule would have been based off time (4 months or whatever number the shop put on the sticker) and not the miles you've driven.
Question as to the oring to seal the block, should the oring fully fill the seat, or will it expand with heat?
It will pinch and expand outward a bit
Do you need to pre-oil the new pump before you fit it?
No need Jarryd, it comes pre lubed enough to install and run right out of the box!
Hi I have 283D,288D, 2870, 2891 code on a 1.6 cooper from 2007, both vanos have been changed but still the issue only when motor is hot, then the car is vibrating when the fault indicator appears,
when motor is cold there is no problem, please any advice ?
Thank you
So you swapped out the VANOS solenoid? Have you tried the Vac pump replacement as that can cause VANOS/timing related codes before its too late. The temperature fluctuation could just have to do with it being in cold start vs not cold start so once its at actual idle it begins to go out of time since its not receiving cold start throttle. Its rare but something could also be wrong with the VANOS sprocket found on the intake side.
@@fcpeuro Thanks for your response,
Indeed I swapped both VANOS (inlet and Exhaust side) but the issue is still there,
So i'm getting those errors :
283D - VANOS Exhaust Adaption Stop
288D - Exhaust camshaft to crankshaft correlation
2870 - VANOS inlet, flank adaption - permanent
2891 - Inlet camshaft to crankshaft correlation
The car is from 2007, so 13 years old, it have 147.000Km, it have been maintained normally, oil changed at the right km etc ...
When the engine is hot (after several km the engine reach is normal temperature) the fault light appears then the car is getting rough, like vibration and power loss. If I turn off the engine it disappears and then it appears again.
When the car is cold there is nothing, no noise, it is running correctly.
I saw that it could be the Vaccum pump as you notice,
I have some question like : why it could not be the distribution chain and the tensioner ? or an air leak ? or the wastegate on the turbocompressor ?
How can i diagnostic the vaccum pumps without vaccum gauge
Thanks a lot for your help
Are the pumps the same on the n18’s? Just bought a 12’ MCS and wanted to do some preventative maintenance. Thanks
Hey Xscalab 44 , lucky for your they upgraded the vacuum pump on the N18 along with the HPFP, so lucky for you it should not be an issue. Its not super rare to have one still fail on occasion, as it functions similarly to the N14, just keep an eye on the gasket (could replace just this), and be aware of any out of the ordinary noises coming from it.
Great thanks.
Could you please help me
I have a check engine light and the diagnostics says i have a failed MAP sensor and O2 number 2 sensor i allready ordered these parts but my vacum pump makes extremly noisy rattle and i can see a lots of oil under the pump leaking on the engine and for some reason my AC is allways empty i cahrged it before 3 months and allready it doesent blow any cold air.
The car allready consumed 2 litres of aditional oil and i have changed the oil before 8 months ( 8k kilometers)
P.s i have a MINI R56 1.6 88kw
Hi B. Dolic, well it sounds like you're having a grand old time with your N14 R56....We would start by replacing the o2 sensor and Map sensor since those are easy to do and you have the parts already. Remove the vacuum pump and inspect it, some noise/rattle is to be expected but excessive play/rubbing OR sticking when spinning the pump is not a good sign and could be symptoms of inevitable failure. It sounds like from the oil your'e seeing it is having an issue sealing to the head of your engine, which is in turn possibly starving the pump from getting proper lubrication (you can replace just the seal as well). Failure of the vacuum pump can be detrimental as mentioned in the video so it may be worth preemptively replacing it regardless. Oil consumption is fairly standard on these n14 engines so without knowing your mileage and how far you are driving in the 8months since the last oil change it is difficult to say for sure whats "normal or not". We suggest having a trained professional inspect your AC system as it can be dangerous to work with and expensive with all the necessary tools (it is likely a leak somewhere in your system).
Is the tapping sound that comes and goes at idle normal it sounds similar to like a knock. I have a Subaru with that type of pump
Ya it is not a quiet pump by any means even under normal working conditions. It should be a consistent tick though nothing like metal grinding etc
FCP Euro thank you for helping 🙏🏻
FCP Euro I heard it today I pressed my brakes a couple times and it went away
Do I have to buy the whole assembly? I just want that tiny black plastic piece that broke off on mine
Hey Lorenzo, you're honestly better off trying to buy a cheap second hand broken vacuum pump and swapping off that plastic nipple. We don't sell that piece by itself though it always comes as a whole assembly. Hope that helps!
I believe my vacuum pump leaked a bit of oil but then hasn't leaked any for a month or so. Would it be worth checking still ?
We'd suggest just pulling it off and inspecting the o-ring/replace the o-rin while its off to ensure a fresh seal and make sure the pump is in working order.
@@fcpeuro thanks
Is it the same for the N18? I would hope they changed the design for the N18 a little.
Brian they indeed redesigned it for the N18, switched it over to this 11667586424 www.fcpeuro.com/products/mini-cooper-vacuum-pump-cooper-11667586424 . Sometimes they smarten up ^.^
FCP Euro Do you know what they did differently? Do the new designs not break the cam if they fail or freeze up?
Mine is held on by 2 8mm bolt, not 3 10mm bolts. Yours looks to be the exact same
You're correct Project Mini , further down in the description we actually noted that ! "*note, it was mentioned it's 3 bolts to take off the Vacuum pump (that is to un-assemble it), it is instead only 2 bolts to remove it from the cylinder head!" When looking at it Ben mentioned the 3 bolts that hold the pump together, not actually the 2 that bolt into the head. Good catch!
FCP Euro actually it’s 4 bolts that hold it together lol i just rebuilt mine last night. It’s my last uploaded video
A common mistake people make is not pre-lubing the new vacuum pump before installing it.

there is suppose to be oil inside the Vacuum pump??
Oil is what is used to lubricate the vac pump from seizing. That's what the tiny passage hole on the head and pump is for!
Hi there! I have this same car, and my issue was that I heard a harsh knocking sound coming from the vacuum pump (almost like a hammering). I took off my pump (lots of oil came out, is that normal?) and I noticed some scoring on the inside of the vacuum chamber cover, but nothing seemed broken. When the cover is off, I am able to move the shaft back and forth, and in the non normal position it will lock. Also, the part that should have some play (the part that connects to the camshaft) can go left and right, as well as up and down on the shaft, is that normal?
The hammering sound is not normal, a small tick is what MINI says to not worry about. Scoring should not be there, that means its running dry and starting to likely fail. The movement in the part that attaches to the cam is normal as you can sort of see in this video as well. Not sure which part you're referring to in regards to the shaft though. How many miles on the car?
So does it suck air from the engine to produce vacuum?

@@fcpeuro thanks 👍🏻
I have just experienced a hard brake pedal and was informed was due to a failed vacuum pump is this true???
Hey Robert, yes this can very much so be true, this vacuum pump is also responsible for your brake booster, and one of the signs of a failing vac pump is an overly hard brake pedal.
@@fcpeuro thank you very much!! Looks like I’m buying a pump haha
@@robtcrider Happy to help let us know if you need anything else for your MINI !
@@fcpeuro thank you I’m sure I will. Plan on attempting to remove it later today I just pray I didn’t destroy my Engine 🤦🏻♂️
@@robtcrider Good luck, I'm sure youre fine if it was completely seized you'd for sure know!
the old vacuum pump failed at 40k? was the oil topped off regularly or neglected? jw if that's from owner or just bad bmw engineering
I've been looking at getting an older MINI (to save money) but now I'm not so sure.
saving on a used mini, forget about it XD
Very disappointed, I don’t recommended it I replaced my vacuum pump in July of 2022 it literally lasted 6 months. This part is very difficult to replace and time consuming but if you have to pay a repair shop because you are not mechanically incline it will be very expensive. Patrick reminder me that their parts are not o.e.m but FCP Euro advertise their parts as being just as good quality. Honestly I saved about 150 dollars not buying from BMW but at the end it will cost me more cause now I have to rent a car while I ship, receive, and replace the new part then hope it last more than 6 months. In conclusion pay more buy OEM at the long run it will be cheaper.
Two 10mm bolts. Not three. lol. 😂
"diagnosis". Takes pump off and spins it by hand. How about hooking a vacuum gauge to the pump while the car is running and comparing it to specs?
It wouldn't spin at all with a gauge on it since it was completely locked which again causes the actual failure. The goal was not show how much vacuum the pump was or wasn't generating but instead testing if its locked or has noticeable grinding. Hooking a gauge up would have been a good idea though to see if there was any difference between the old (working) and new on a car.
@@fcpeuro Then title the video "How to check for a failing vacuum pump and what happens when it fails". If you are going to make a video titled "diagnosis" then you should present all methods of diagnosis not just what your particular situation was. These pumps are expensive and showing the viewers all methods of inspection and testing might save them from changing a part that is not faulty.
Appreciate your insight @@rob3071
@@rob3071 Shut up.
Mini's are garbage!
