- I got a non-genuine valve cover replacement for my N14 mini R56 Cooper S. Found it has a manufacturing defect and so did the replacement. Here's how to fix it.
Also includes an explanation of the PCV system workings. - Věda a technologie
Note: Correct N14 crankcase / valve cover vacuum is 22 millibar.
This could be checked by making a DIY 'manometer'. See link below. 22 millibar is 8.8 inches of water.

Can you run a hose from the back of the valve cover to a catch can (1in 2 out) then on the outlet side of the catch can run a hose to the intake and a hose to the intake manifold and put a breather on the side of the valve cover that you would normally hook to the intake. Do you think that would lose any positive or negative pressure?
I bought mine for 100$ because I didn't trust ebay ones.
Well after I installed it my idle was higher than normal and after 50 miles the check engine light came on. It was p0507 (idle control system higher than expected).
After having this issue I started googling and I found you video. I checked the valve you were showing with a mirror and sure enough it was open.
Turn the engine on and it was sucking air....
I just wanted to thank you for helping with you video!
Jesús!!!! This is the best tip ever!! I got this problem with my mini Cooper, after too many diagnosis and testing I was prepared to spend hundreds of dollars to repairs and I stumbled into your video and did it as ultime resource...and it work like magic, and only spend 2 dollars of some plastic glue and a burn fingers tip..🤣🤣 an that was it... Thank you some much.
Hi what is the name of the plastic glue you use please, if you don't mine Mr. Acuna? Thanks.
@@jonasesguerra6738 also need to know this!
The large circular disk has another valve under it usually the main cause it gets gunked up sticks shut or open it shut fluctuate so oil doesn't come up most suffer with white gunk like a head gasket from huge rocker cover causing condensation so check that too it doesn't come open easily so buy a genuine new part will fix 99% of idling problems and gunked up inlet valves as the vapours burn on .. I put an extra oil catch in too works a treat
Thanks for the theory of operation. 99% of other videos are the physical installation and removal. They just change parts without confirming it is not working (or how it is not). This video is a gold. Make more pls as u are well capable of understanding how things work.
Fantastic and very thorough explanation of the R56 N14 PCV system. Thank you!
Yes, diaphragm works precisely as you described 🤩
Really useful video.
Thanks for sharing.
Thanks, first video of the inner workings. There's been a lot of debate over how the pcv system works on this engine.
Thank you for this. You certainly have cleared up the mystery surrounding this valve cover. Much appreciated.
I've shared this with so many people. You have cleared up the mini pcv mystery. Fixed my car for £38 using the Peugeot part and now it's great no more p1497 code for me.
Is that how much the valve cover costs from peugeot?? I have a 207 gti and bought an aftermarket "mini" item for double that
@@RaifRaif85 that's from eBay. The mould tool to make these parts makes them for the manufacturer and the spares companies. It's a myth that the quality varies depending on who you buy from. I worked injection mould tooling for four years.
@@emailandy79 I can belive that. I bought a "branded" European made part and it has the same issue as the ebay ones from the far east
it seems!
Superb and very informative thanks.. and thanks for no crapy music n crazy loud volume...... learnt exactly what I wanted to.. Thanks again
Thanks for taking time to make this video 😊
Thanks so much! I have this exact problem with the same aftermarket valve cover and was running out of ideas trying to find the unmetered air leak
I think the orange valve is where pressure enters. The hole in the middle is for deposits to return to crankcase.
Thanks very much for your practical explanation. I’ve just bought a Valve Cover from Neo Brothers and will follow your recommendations depending on how it performs. I’m looking to solve my high oil consumption and unsteady idle with a properly operating PCV system.
High Oil consumption usually sign of leaks. You can get a Oil Catch Can, that will help. Also, when you empty it, you can tell a lot about the Engine just by the Can.
@@JodBronson A bad pcv will create too much pressure and push the oil down past all seals and burn, creating the blue smoke. does not always mean worn rings
How did you get on with the Neo Brothers cover Harry ?
@Mike B
Good as far as I can remember hehe. I'm sure my notes will explain if I were to go back through it. I no longer have the car so I need to sell my Bentley publishers manual and timing chain replacement tools that I no longer need.
@@harrywilkinson444 Many thanks Harry 👍🏻
Thank you sir. Very well explained and saved me alot of time diagnosing this exact issue my 207 gti
Thx mate. Didn't know this part is built so thought out
Big big thanks for this video! It helped a lot for me. I had same problem by my Peogeot 5008. Nice finding and solution! Great job! Thanks one more time!
Good info. Thanks!
If i have to install an oil catch can (OCC) on the passenger side, can i just plug/close the intake manifold (no hose). So inlet side of the OCC will be the oil and the outlet side will just be an air filter breather (instead of connecting a hose heading to the intake manifold)? Thanks👍
Thank you for the great instructions good sir, is it possible to take off the cover that will expose the two valves and work on them, without taking the valve cover off the engine? I have a 2009 s model that has leaking oil on the cover and check engine light is on. I am suspecting that it is a cover issue.
Great video, well explained! Which glue did you use to get the cover back on?
Also, is the oil supposed to be just in the middle section?
Thanks for that in depth video, I’m currently investigating a weird (I think) figure of -2.80% additive mixture correction on tickover so wondering if PCV is to blame 🤷🏼♂️
Awesome video, helps to fully understand how it works. Some time ago I plugged the passenger side of the PCV just like you, becouse it was making my engine super knocking.
Would this cause oil debris to fly out of the tail pipe and cover the back of the car?
@@p1sstoph3 in my case - no difference.
Thanks so much, i replaced with cheap aftermarket rocker cover too. Will check for airflow.
Awesome video, much needed information in regards to these valve cover replacements. If you ever find out what the plug in the rear is for PLEASE let us know. The only info I could find was it has something to do with emissions with the Minis imported to the USA. Euro Austral/Asia don’t require that section I think.
Apparently it is supposed to be plugged. I don't remember where I read it, but the handle on the plug is designed to snap off so it can fit next to the air box. N14, plug the hole.
@@TensonUK i have a plug with and without a handle? I assume either is ok ?
At the end, did you solve your problems after that? Bte thank you very much for the video it really helped me
Great video - now I understand how that all works 🙂
I wish i had come to your video instead of wasting last couple of days on random videos and instructions, a big thank you. Could you please confirm if you manage to seal the cover properly airtight before I damage mine.
Thank you for the tricks. It solve my p1497 code. Everything back to normal.
What did you use to glue it back?
I've done this and it's not solved it. Still getting that code :(
Hi, I have seen some aftermarket aluminum valve cover, do you think aluminum valve cover would make any difference, as I think those can be disassembled and easy to replace pcv parts.
This Valve Cover is design for Turbo and Non-Turbo. Non-Turbo you do not need the hose from the right. Just plug it up and you will have no vacuum issues.
What is the effect if i block the pcv hole line ?
@@ahmadzambri6679 - Depend on your Engine. You will have oilly engine vapor issues. Waste gases exit the crankcase through the valve, but cannot enter and that is the main function. Also some cases, there are many lines branched off from that too, got to be careful, unless you do it right from the PCV itself.
me is turbo 207cc thp and right hose suck air on new non geniun oem valve cover.After replacement valve cover appeared p2279 code and coolant radiator fan run in full speed and no off even after engine off🤔🤔🤔
250th subscrober yeah!
I'd be interested to hear what you've used to install the OCC on the intake side (hose inner diameter, what type of collars, etc). I have one on the turbo side but the hose at the back is much less accessible, made flimsy plastic and connects to at least one plastic nipple _which makes collars tightening frightening....
I've tried three OCC setups on my N14: BSH, Moroso, and a name-brand I don't remember. The best, by far, is the Moroso. The finished installation is clean and trouble free. Brands that have good recommendations, but I haven't tried include Mishmoto and GTT.
Actual GENIUS.
Excellent video, please provide an update after 1 year.
Hello, so this doesn't have a pcv valve? Or does it have one at either end??
nice and instructive video. Did I understand correctly? when the engine is running in neutral position, the left side tube of the valve cover should be open valve and release gases through the hose in the inlet manifold, and the right side,tube is should be completely closed and should not emit gases or sucks air ??? ? For me, the new valve cover in neutral position, draws air a lot from the right side where the hose from the turbo is connected and shows p2279 error, and coolant radiator fan running in full speed & dont stop.It new valve cover,bat is not geniun part oem.
Fix it or you'll turn gay
Great Video, I too have high oil consumption but I think its tired piston rings as I only get a puff of blue smoke after a long overrun and I know its not the turbo and the valve stem seals as I have changed them.
Nope not the piston rings, its the crappy PCV system. Check the hose that goes to the intake for cracks first and then install two catch cans. Once the engine burns all the oil you most likely have in the intercooler you'll stop blowing smoke. You'll probably also want to clean your intake valves.
@@bluefordpickup It was the piston rings as I have just rebuilt the engine and no more burning oil 👍
@@darrenastbury5280 Roger that. Good to know. BTW, how bad were your intake valves when you pulled the engine apart?
hello .. the video is very interesting and I think you are the only one on CZcams that explains this problem and the operation of this valve cover and PCV ... I have also changed it as well as a plastic called polyamide because it withstands more heat but Unfortunately it comes with exactly the same problem...I want to ask you a question and I don't know if you remember the design of the valve correctly...instead of taking off the top cover, couldn't you push the valve with a screwdriver? the guide in the center of the valve is glued or is a joint piece and must be cut by obligation.... looking for a lot of information on this subject in some forum I have read that they come like this to avoid oil consumption and that the engine valves are not dirty ... in my car when starting in first gear I am noticing how the engine shakes a little then everything goes normally ... I have disassembled the tube that goes from the PCV to the turbo and everything is dry and clean...with the obd machine I get the same 2B64 code...could the engine be affected if it doesn't solve this? I await your response... greetings and thanks for your time
Check the hose that goes to the intake manifold for cracks. It might be broken. I hope you're still alive.
But the pcv hose is after the maf sensor so why would it cause an unmetered air code?
Hello, what kind of glue did you use to reseal this part? Thanks!
Upol Tiger Seal
Whale sperm
GREAT JOB THANKS FOR THE VIDEO
The air is getting measured as it goes through the mass before it reaches the rocker cover.
My new unbranded valve cover has the same issue. What did you use to reseal the cap?
Upol Tiger Seal. I had thought hard about what to use, then talked with someone who said they had resealed PCV systems before using Tiger Seal and still good a year later.
@@TensonUK If the seal is not air tight, would this bring up any issues? Picking up a error that points to a air fuel mixture error. I can hear a audible sucking where it should be sealed. Error code P2191 Too lean at higher load bank 1
That's a great video thanks
What glue did u go with to seal that back?
did you experienced oil leakage surrounding that pcv area?
great vid !!!!!
is this a EP6 engine? this valve cover looks similar to it
I've been having a p1497 issue since I did my timing chain and new valve cover Install. I watched your video and pulled the hose off the right side of the valve cover yesterday and at idle it sucks air in strongly. So is this the sign that my new valve cover needs to have this truck done?
Hey I'm having the exact same problem! Did you fix it I'm the end??
@@purelegend24 I got a p1497 after I change my new after market valve cover last week.
And I I did that fix today. Cut the pin of that plug. After this everything back to normal. I got the full performance again.
Thank you very much @TensonUK who share that tricks here.
Wicked! What did you use to glue it down?
the problem is on me 207cc turbo,new after market valve cover sucket air in the right hose when the attached turbo hose.And p2279code, radiator coolant fan working on full speed after start the engine and dont off even off engine😤😤😤😤
@@MultiXANTIA1 exact same for me on my 207 gti after fitting aftermarket valve cover!
Brilliant thanks 😊
Glue used was Upol Tiger Seal as confirmed in comments
The genuine cover has hard flaps instead of the rubber round seals I must add the cover must be stuck down with so seriously strong glue as the valve nearest the timing change is pressurised to what boost pressure is good luck
thank you
muy bueno !!
can i use a rtv to put the cover back on or does it have to be some kind of plastic glue
Upol Tiger Seal
So I have a question that I can’t fully figure out. My 08, r56, s, I got it used and it has this same cover on it. The left side is not connected to anything at all. I’m in the USA, so is that left side supposed to be attached, or have they potentially modified this? My issue is a lot of oil debris is getting thrown out the exhaust onto the back of my car
sounds like they deleted the intake routing for the positive charge side. Reinstalling this will allow the oil to recirculate and get burned as apposed to just spit out.
Yes it's supposed to be attached. Does it have an aftermarket intake? I would fix this issue immediately, you're over pressurizing your crankcase, you probably have oil leaks all over the place, including your valves and pistons.
The big thing is a orange diaphragm and they can split which causes problems also.
You can buy replacements i think 🤔
Hi what glue did you end up using
Upol Tiger Seal
Not only is it bad to block them off bcuz of less - pressure it's also bad bcuz water will build up in the crank case from heat cycles which will make goopy oil since the water is not being sucked out. Don't block them off if your not gonna change your oil at very short intervals such as 2000 to 3000 miles or every 3 to 4 months. This is not an opinion it is proven fact.
Do you mean capping the intake manifold pcv hose?
Do remember there will still be suction on the valve cover from the turbo inlet side. It's just not ideal as it encourages condensed oil and water in the intercooler.
@@TensonUK any effection come if i block/capping pcv hole?
Agreed, the whole point of the system is that the engine burns off the moisture and throws it out the exhaust.
