Another great vid, and this one is good for my 2013 X3. I'm doing this now for my 2013 X3 which is 99% similar. I did drop the back most 11 mm nut but will get it off the bottom shield tomorrow (Got it). Also, those press on rubber wire hangers on the back are crazy nasty to pull up. Whoever put on the lower short E-torx on the housing way over-torqued it and I was worried it wouldn't come loose using 1/4" drive and socket, but soaked in penetrating oil for a while and got it, but had to undo the "mickey mouse ears" hose connection to make room for the socket. I couldn't get it with the ratcheting wrench, my hands not strong enough. I used a dab or crazy glue to hold the rearmost manifold bolt into the socket back there. It worked too good, had a hard time getting the socket out! I'm going to replace the serpentine belt and upper rad hose because they were soaked with oil and I dumped quite a bit of anti-freeze too. Tomorrow I'll finish up after a good cleaning and new gaskets. I didn't bleed the coolant, just added some. I'll do the oil /filter change tomorrow. Thanks again for a really quality effort. The job is done, no leaks and running well.

Great tutorial, I'm very glad to see you're back to making videos. One note for anyone doing this, the BMW blue coolant is not premixed (at least the type I've used), and should be diluted 1:1 with distilled water only. Of course, trust the directions on the bottle over me. I love the plastic bag trick to protect your belts, I wish I had done the same when changing the thermostat on my E46 328i (I used a plastic gallon water jug cut into a funnel like shape which only worked OK). I'd also recommend removing the plastic covers underneath the engine and putting puppy pads on the ground (or a large shallow container) to help contain the mess. Keep any kids and pets away as as the ethylene glycol in coolant is apparently both tasty and very poisonous.

[@AskTheCarExperts]

Thank you for the great comment! Very good advice! The under body panels can be a pain to take off on the ground but it is worth the time since you will not have to clean up the mess. I use what we call pig mats at work for spills and the puppy pad idea is fantastic! Also thank you for the notes on the coolant. This is a very helpful comment for everyone!

[@V10PDTDI]

Thanks for the video it’s very well done it’s not that I haven’t done any yet but it’s interesting to see if there’s a different way to do it and there is I didn’t know about the A/C flexible lines but what I do on all BMW now is replace the plastic coolant flange close to the short bolt on the oil filter housing I buy it from my German Car part suppler it’s made of aluminum I just cut the rubber hose close to the metal clip then you loose very little hose this is where I drain most of the coolant. One other thing I do is remove the oil filter From the housing then suck all the oil from it so it doesn’t leak as much when you remove the housing the broken cylinder head bolt I saw this for the first time not that long ago.

I will change the gaskets next week. The only thing that disturbes me in this video is the fact you cannot check if the intake manifold gaskets are still in place when you retight the intake

[@tteitei]

Hi, great video. Just wanted to confirm some of the tools that you used. Please confirm the size of the ratchet wrench you used on the lower bolt holding the oil filter housing.Was it a E8 or E10? You mention that it's a E8 but think its a E10. Also are all the torx sockets you used are E10/E12 and the socket you used for the manifold bolts/nuts a standard 6 point 11mm? Thanks.

[@AskTheCarExperts]

Hello, Yes the lower bolt is an E10 and you will need the E10 and E12 socket. Swivel sockets are helpful and the intake manifold should be an 11 mm 6 point. Thanks for watching and commenting.

[@voicevision3527]

Hello, what size of socket is for the hidden screw?

[@Berg1484]

Thanks for the very helpful video. Quick question...when I was putting the intake manifold back on, the second to last nut slipped and fell down before I secured it on the post. I reached down with a magnet but came up empty. The manifold was fully seated and it looks like it fell into an open area. Could it have fallen into a critical spot and do major damage or is it likely sitting on a rail or down on the splash guard? Thanks again.

[@AskTheCarExperts]

Hi Joel, Most likely it fell into a cavity outside the engine. If the intake was fully seated it is unlikely it fell into the intake port. But if it did find its way in then major engine damage can result. If you have any doubt you should inspect the intake ports and remove the plug and inspect the cylinder. That would be a very bad day to damage your engine over 1 lost nut.

[@Berg1484]

@@AskTheCarExperts Thank you for the quick response. Very helpful.

[@davechiluk9822]

Seems like there's a lot of stuff that gets removed for this one. Any thoughts on other good "while you are in there" type things? I'm thinking acccessory belt and possibly cleaning out the intake/walnut blasting.

[@AskTheCarExperts]

Hi David, That's a great question. The N55 engine does not typically collect carbon in the intake. That was common on the N54. Take a peak at the intake ports but you most likely will not need to clean them. I would recommend the belt tensioner as it is a common failure.

[@zhengzhengfeng4729]

Thanks for detailed instructions. Have you tried to remove the cooler with the OFH? Would that mix more coolant with the oil? About to try this and just wondering

Man I’m about done except the last bolt by the manifold. It goes in quarter way and then no more turn or very hard to. I tried a brand new bolt and the same happens. Any advice appreciate you.

[@AskTheCarExperts]

You may need to loosen all of the other bolts and put that one in first. Blow out the hole with air if you can. Hopefully it did not get cross threaded.

[@ismaeelzia5435]

Thanks for the video, only one question do i need to drain the engine oil?

[@AskTheCarExperts]

Hello Ismaeel, I would recommend performing an oil change as you may introduce some coolant into the engine oil.

[@RBPD92]

Could an oil cooler fail? and allow oil go into cooling system??.... I have changed both gaskets and coolant still gets milky and the engine runs good, so I don't think in a head gasket.... Thank you for replying.

[@AskTheCarExperts]

Hello RP, Yes you can get mixing from a failed oil cooler. When you did the gasket did you make sure there was no pitting on the mating surface? If there is you need to use JB weld to fill the pitting and sand smooth. Also once you get oil and coolant mix in the cooling system is is very hard to remove it. There is always some residual. Keep removing the top layer of the reservoir and top off.

[@fabiodarocha2842]

I didn't get the part that you have to use a battery charger. Did you disconnect the battery in the trunk by any chance?

How can you tell if your oil filter housing gasket is leaking? I can’t get a good angle to visually check.

[@AskTheCarExperts]

It's all by feel in the back. You can try a swivel with electrical tape wrapped around the pivot for better tension and control. Tap the end of the extension to help seat the socket.

[@benten6301]

@@AskTheCarExperts I might have to unscrew the barrier and move wires to get to that nut. I got a mirror but them wires blocking my view. It feels like the stud and nut are angle and not perpendicular. This is why I couldn't get in the 11 or 12 mm . My belt brokes due to leaking OHG. I took off the fan cowl and removed the crank pulley. Shredded belts was wrapped behind crank pulley. I removed the remnants and the seal looks new. However, some electrical wires is torn at the sleeve so I will have to wrap them with electrical tape. Thanks for the reply and the video is awesome. Much appreciate your time.

[@AskTheCarExperts]

Hi, yes there is a procedure I would recommend. The current procedure to do when the oil circuit is opened is to turn the engine over by hand 2 x and then with a charger on the vehicle and the fuel system disabled (fuel pump fuse or unplug the low side pump) crank the engine for 5 sec intervals letting the starter rest for 1 min in between and do this 4x. This re prunes the system. Also you should double up on your oil changes and try to avoid short distance driving that allows water build up in the oil. I hope this helps!

[@primoz990]

AskTheCarExperts oooh now i understand. So there may be a true connection betewen OFHG replacement and rod bearing failure. Thanks a lot for the life saving advice! It all makes sense now :)

[@AskTheCarExperts]

@@primoz990 Your welcome :) This should be performed on any repair that interrupts the oil circuit.

[@primoz990]

AskTheCarExperts Yes, you are 100% right on that. I see you have a lot experience with BMW N series engines in general. Any experience with spun rod bearings on the N55? Some people had this fatal issue on low mileage cars for no obvious reason. Any info on that maybe? I am thinking to preventive replace the rod bearings on my N55 with 125k miles.

[@AskTheCarExperts]

@@primoz990 I have seen quite a few bottom end problems on the N55. I would also recommend checking your oil filter and looking for any signs of copper. I think most failures stem from BMW's current oil change interval. People I know that do an oil change every 5,000 or less have a lot less problems. I have also seen failures from cold weather due to emulsified oil due to short distance driving. I know in Canada they install block heaters. I think this should be done in all cold weather climates. I have yet to install one though :)

Hi Dx, Yes this is the usually reason. When you remove the components check the sealing surface for pitting. If you see some you can fill with JB weld and sand down to correct. You will need to flush the cooling system a few times but keep in mind there usually always is some residue left. Just keep removing the small amount that comes to the top over time and it should help clean it out.

Hi Thank you for the excellent and in great detail video . great explanation and camera work. I have a 2013 bmw x5 35i 3.0 litre turbo. QUESTION>>> It seems this is a common problem with these gasket failures, Does BMW have these replacement gaskets made out of revised/ better composite material?? If not it will only be a matter of time to have to be redone again and again in the future. Or is there another gasket company (Felpro/McCord) that do obviously make a better revision gasket to replace these "known problem" gaskets. ty Sir in advance

[@AskTheCarExperts]

This is usually an age and time related failure due to expansion and contraction. Bmw does not make a different gasket. It is the same material as the original. You could try a different gasket but I am not familiar with other brand gaskets and longevity.

That's great Terrence! Being preventative is smart. Once the oil gets onto the drive belts they need to be replaced and I have often seen the drive belts come apart leading to engine damage.

@@AskTheCarExperts ok great it's a n55 engine, I took my car to the dealer for an airbag recall and they said I have a leak on the oil filter housing gasket. I dont see any leaks or any pooling on my driveway, is there any way to know for sure that's the problem? My mileage is at 87k, you think I should just get it done as a preventive measure. Also do you think I should change belt and tensor while I'm in the process? Sorry for the overwhelming amount of questions..

@@infamous87ny Take a look at the underside of the housing. This is usually where the leak starts. Using and inspection mirror can help. Also check the coolant lines going to the cooler for any signs of oil which can make the hoses swell. I hope this helps. If your not a subscriber please subscribe :)

It is a good idea to prime after the repair. Disable the injectors or fuel pump and crank the engine over a few times for 5 sec intervals and wait a few minutes in between to let the starter rest.

No I did remove antifreeze hose partially blocking the bolt. Did want another job on top of that. I've heard the o ring break off inside of Housing. Creating another headache. I've done many jobs but this one kinda space limited especially tighting the lower bolt back in. Also off set hed ratchet would have helped. I Have more than enough tools that I've completed this job on. It's just space constraints. Don't be discouraged the job can be done just have patience

[@ChaosFetus]

This may be silly to ask, but do you need to drain the oil before doing this repair?

[@AskTheCarExperts]

Hi John, That is a good question. You do not need to drain the oil. Crack the oil filter loose and wait a few minutes for the oil to drain back from the housing. Then you are good to go. Avoid spraying any cleaner into the engine. If you do or you get a lot of coolent into the ports then you can do an oil change after the repair. I hope this helps. My best to you and your family.

[@Merlin5150III]

Here is the service procedure...... newTIS.info beta BMW E70 X5 M SAV / Repair Manuals and Technical Data / 11 Engine / 11 00 Engine / Repair notes on renewing the engine Engine damage due to lack of engine oil. Lack of engine oil after the oil circuit components are repaired or after the engine is renewed may cause damage to the engine. Do not start the engine after the oil circuit components are repaired or after the engine is renewed without following the repair notes. The repair notes on carrying out repairs on the oil circuit components or renewing the engine must be followed. For additional information, see: Repair notes on carrying out repairs on the oil circuit components or renewing the engine Problem After the engine is renewed, the lack of engine oil may damage the engine. Cause An exchange engine is not pre-filled with engine oil. An exchange engine may still have an unknown residual amount of engine oil in the oil sump resulting from the assembly of the engine. This residual amount of engine oil is not sufficient to operate the engine. A lack of supply of engine oil due to a low oil level may damage the engine immediately after the engine is started. The electronic measurement of the oil level is possible only if the engine is running and the engine oil is at operating temperature. The electronic measurement of the oil level therefore must not be carried out. Solution The engine oil must be drained fully after the exchange engine is installed. For additional information, see: Maintenance instructions "00 00 252 and 00 00 610 Engine oil service". Observe the sign in the engine compartment! Only pour in approved engine oil with the correct SAE viscosity classification. Fill the correct quantity of engine oil in the engine.

An excessively long and uninterrupted operating period of the starter motor may damage the starter motor. Note the maximum permissible uninterrupted operating period of the starter motor. Allow the starter motor to cool down before a new operation. Before the first engine start, the engine only needs to be turned with the starter (without combustion) for a few seconds.. The maximum permissible uninterrupted operating period must not be exceeded. Additionally, the starter motor must be cooled down for a few seconds before being operated again. Starter motor Maximum permissible uninterrupted operating period 10 s of the starter motor Minimum cooling-down period immediately after 20 s operation The fuse of the electric fuel pump must be removed to guarantee this. Turning the engine with the starter motor (without combustion) ensures that the engine has a sufficient supply of engine oil to start the engine regularly thereafter. Turn the engine with the starter motor (without combustion) for the stipulated period of time. Allow the starter motor to cool down for the stipulated period of time. Carry out the previous two steps 2 more times. Then install the fuse of the electric fuel pump. Delete the fault memory. Start engine. Bring the engine to operating temperature.

[@rollydoucet8909]

The rubber gaskets between the oil filter housing and the engine, and the oil cooler to the filter housing were changed on my car about two years ago, and now the leak has returned. I bought the two gaskets from my BMW dealer and they're quite expensive for a couple of pieces of rubber. Supposedly, the original equipment gaskets from BMW aren't the best quality, and the aftermarket parts are better. I guess I'm about to find out.

[@AskTheCarExperts]

@@rollydoucet8909 Glad you told me that. Make sure to check the sealing surface for any corrosion or imperfections in the sealing surface. If you find pitting it will leak again. The fix is to use JB weld and fill the pitting and sand the surface smooth. Just a small amount of JB. But it had to cure before you sand. Hope this helps!

[@rollydoucet8909]

@@AskTheCarExperts I had no issues with pitting. My car had only 23,650 miles on it in 2017 as it wasn't driven much by the previous owner. I store it every winter, and the leak started shortly after I got it out of storage. The factory warranty expired during the winter. Now, I've got just under 40,000 miles on it and the leak has returned. More than one person has told me that BMW outsourced much of their seals, rubber, and plastic components to the wrong manufacturer for a couple of years and that's why coolant and oil leak issues are so common. This time, I bought gaskets from an aftermarket supplier that specializes in German cars. Supposed to be better quality, we'll see.
