- How to replace the upper intake gaskets on a BMW m57 diesel. This particular car I am working with here is a 2010 335d. With age and heat from the engine, these gaskets will dry out, become hard and potentially leak. If leaking, they can cause issues on how the engine runs. #bmwm57 #bmw335d #turnermotorsport

Tools/Supplies Needed:
-8mm, 10mm, 11mm, 13mm sockets with ratchet
-e14, e18 sockets
-5mm allen wrench
-degrease
-clean rags
-side cutters
-long magnet
-new gaskets
-swirl flap delete kit
-silicone spray
-small screwdriver or pick
-t20 driver
Procedure:
It’s a good idea to disconnect the battery. This requires a 10mm socket, which I have already done. Remove the 6 8mm screws holding down the cabin filter cover.
Then lift off the cabin filter cover. Unclip the sensor for the hood. Pull out the side tabs and remove the outer covers by the hood shocks.
Remove the 2 8 mm screws on each side of the windshield cowl. There will be one on each side.
If you haven’t already, unclipped the wire that goes across the engine bay under that plastic trim piece above the engine cover.
Lift that plastic cover and then pull towards the front of the car. There will be a wire clip that also needs to be disconnected to fully remove this cover.
Before getting any further, it’s always a good idea to vacuum up any debris which can potentially fall inside the engine. Using an e14 socket, remove the two bolts on each of the strut towers for the strut brace.
Remove the plastic cover at the center of the windshield cowl, then loosen the e18 bolt here. There is no need to remove it as the strut braces as they have a slotted hole where they slide in under the bolt head.
Then remove the strut braces for each side. Make note of their orientation as they only fit in one position.
Remove the 13mm nut for the power wire that goes across the engine bay. As mentioned earlier, you should have disconnected the battery so there is no chance of a short here.
Remove the 7 5mm socket head bolts using a 3/8 drive ratchet. This engine cover comes out in two pieces, I will show you that in a moment.
Once those fasteners are out, wipe around the oil fill location, then remove the filler cap.
Lift out the first part of the engine cover. Reinstall that oil fill cap.
Remove the 3 10mm bolts holding on the center section plastic trim panel on the firewall. There are two styles of fasteners here, make sure you note their location.
If you haven’t already, pull out that rubber gasket. Then lift out the cover, you may need to pull up on the windshield cowl to help with movement.
Now remove the back section of the engine cover. This is a tight fit and will require some patience when removing. Make sure you don’t damage the sound insulation.
Remove the 2 10mm bolts towards the back corner of the intake on the driver's side. There will be one for the engine oil dipstick bracket and another for a bracket on the rear.
Disconnect the electrical plug for the MAP sensor. Simply press the tag and pull it off.
Disconnect the electrical connector on the rear behind the intake. And then disconnect another below the MAP sensor. Using cutters, remove the cable tie holding on the one wiring harness. Using a standard screwdriver, gently pry off the electrical connector for the butterfly flap motor.
Disconnect the wiring harness from the bracket. Disconnect the electrical connector on top of this assembly along with removing the harness from the wiring retaining clip.

Really underappreciated video here. I've got a friend with one of these cars and he's clearly got some leaks from the intake plenum, so this job is on the agenda. Immediate subscriber since it looks like you've got a few more videos on this engine. Thank you!
Thank you so much for the feedback and support! Yep, I definitely have some videos for the M57 and will be having more in the future.
@@4DIYers Thanks again for the great video. Job done on my neighbor's 2010 335d. He'd already had a DPF and EGR delete done but whoever did that didn't clean up the intake at all, replace gaskets, or clean/delete the swirl flaps. I thoroughly cleaned everything using a similar method to yours (giant plastic tub and cleaner), but we did keep the swirl flaps since no EGR means very limited likelihood of them getting gunked up again in the future and they do serve a purpose. I used some Honda Shin Etsu grease on the rubber moldings on those to re-condition them as best as possible. Definitely appreciate providing the torque specs as well - car runs great now and no signs of any issues.
Great video and thanks for the clear and concise explanations. I've used your E39 videos plenty also!
I'm going to use this in order to help me replace the glow plug regulator (under the manifold) on my 2008 335d Saloon, after 175k miles. Keep up the great content.
Thank you so much, really appreciate the kind words! Small world too, both of us owning the same cars. How do you like the diesel?
perfect video!
Thank you!
Excellent tutorial. Not too bad of a job. My back would hurt if I did all that bending over. Getting too old now 😀
Thank you so much! Yeah I know the feeling lol. There's definitely been a few times where I'm like "oh wait, I can't bent like this anymore" or I get the really annoying stiff neck if I move the wrong way.
thanks
You're welcome!
I should also delete the swirl flaps and install the blank kit.
