How to clean intake manifold Carbon cleaning BMW N57 N47 F10 F11 518d 520d 530d 535d 330d 335d X4 X5

Was going to clean mine this weekend, but then remember car is in with BMW for 3 recalls!

[@TheKeenMechanic]

It will be a great job when done🤝🏻

[@nemz7505]

This is a great idea but what's even better is soaking in a large container of caustic soda solution, rinse and repeat a couple of times and it looks like brand new with no manual scrubbing required at all

[@TheKeenMechanic]

This is very good to know. Thanks very much for letting me know buddy👏🙌🏻

I just cleaned my intake. 2 hours. Oven cleaner, brush on a screwdriver and dishwasher tablets. Then a long time with hot water + pressure wash.

[@TheKeenMechanic]

Nice one. 2hrs is very good. Glad to be able to help.

[@VIW3784]

Great idea, turned out really well. Did you test to see if the mechanism is worn, I see some people are putting a screw in the actuator to act as a stop when their manifold starts wearing out and the flaps go past the stop point.

[@TheKeenMechanic]

No wear issue on this one. It was well lubricated with engine oil😁

Great video, how did you clean the valves?

[@TheKeenMechanic]

Hi I have a video on the valve and valve ports cleaning🤝🏻

[@herrbrahms]

There are two broad categories of oven cleaner: those with and those without sodium hydroxide (lye) which is corrosive. I'm American so I am not familiar with that product. I did some research and it appears you used the corrosive kind. Did you notice any degradation in the ABS plastic or any aluminum or rubber parts?

[@TheKeenMechanic]

Use the corrosive one without any fear. I have done this so many times in the past 15 years I can't even count. I have never had any issues with either plastic or metal parts. Hope this helps.

@@TheKeenMechanic I greatly appreciate your quick response, thank you.

Did it make a big difference after the clean?

[@TheKeenMechanic]

Massive difference buddy. Engine sounds smoother, pulls better and better fuel economy🤝

[@G3516dude]

That’s an awesome job and great idea 👍🏻 thanks

[@TheKeenMechanic]

@@G3516dude Thanks for watching

[@thejudge-kv2jk]

You reckon the oven cleaner will be okay on gaskets? Might they corode?

[@TheKeenMechanic]

I would remove the gaskets if you can if you are going to reuse them. If you can afford replace all gaskets and seals after the cleaning. Thanks for watching and for your comment.

GREAT JOB

[@TheKeenMechanic]

Cheers bro🤝

[@antoniohinojos3808]

Right on mate 💯

[@TheKeenMechanic]

Thanks buddy🔧🔩🤝

[@bravebrowser261]

Is there a way to clean it without removing

[@TheKeenMechanic]

Not really, if you want to do a good job. There are services and chemical products that claim to clean it but it all goes through the engine and cloggs up the dpf and wears the engine out prematurely. It is not difficult to rwmove and clean it as I have shown

[@bravebrowser261]

@@TheKeenMechanic it looks a nightmare to take off lol never mind putting back on lol

[@TheKeenMechanic]

@@bravebrowser261 I have done it a few times this week and it really isn't too bad as long as you take care

[@bravebrowser261]

@@TheKeenMechanic I’m a mapper so we super lazy lol

[@TheKeenMechanic]

@@bravebrowser261 🤣 Can I ask you is it a big job to disable the EGR on N57. It makes a mess and cloggs up these engines so bad in no time.

Go Bad Boy !

Thanks again. You are a legend. Thanks for watching all my F10 videos. If you have never tried Mr.Muscle for cleaning heavy oil and carbon this will be a game changer for you. I can highly recommend this method as it is cheap and very effective
