Use care when adding oil to filter housing without a filter. Some folks have poured oil in the housing and didn’t realize bits of that foil seal were in the oil. The foil made its way through because there was no filter installed. It clogged a passage and spun a bearing.

[@herlegz6969]

Basic 101 oil usage is to always use a strainer to put any oil in an engine. But these days clowns destroy mechanical systems with negligence by not doing basics.

[@osagyefoghanaba]

Much appreciated for this useful information which sadly is not included in the ISTA+ repair guide but issued under BMW Service Bulletin (SI B11 09 15) March 2016 Technical Service. Thank you 🙏

[@HowToDoitright]

Glad it helped. Please like and subscribe as it helps my channel supporting charity :)

[@benten6301]

I pulled 2 of the ones by the battery, both are black connectors. Engine still turns over. There are 3 more bigger connectectors by battery, 2 black and 1 white. They are connecting vertically away from the battery. Do you think I should try them.

[@sajadeshahidpour2008]

Greetings from France, many thanks for your video ! Dumb question sorry : is priming the engine something that also should be done after a classical oil change ? Or if the car stayed in the garage for a certain long time ?

[@HowToDoitright]

If the car has been parked for a very very long time then maybe yes but I never did after an oil change. But it’s a good idea as it helps lubricate the engine.

[@sajadeshahidpour2008]

@@HowToDoitright Thank you for your answer! Cheers.

[@benten6301]

I am goinf to try taking injectors connector out. Could you do best to describe the technique. I did watch your cover gasket video. Do I use a small flat head driver and wedge it to the back of connector. I am not sure which side is the back.

[@HowToDoitright]

ben ten it’s hard to explain. Yes you have to use the small screw driver head. I suggest play my video I believe the process is in the middle of the video. Zoom in and see the connector. There you can see which side I inserted it. Remember as you insert you have to pull on the connector wire. It won’t break so don’t worry. They are strong. Just don’t yank on it like crazy but a decent pull won’t break it. Insert screw and keep pulling. It will come out.

[@aidenp5768]

When priming the oil, does the oil go through the entire engine or just a few spots? It would be useful to prime the engines after the car sitting in the garage after weeks of no driving.

[@HowToDoitright]

It mainly fill up oil in the filter housing via the pump. If the car has been sitting the filter housing still has oil in it but with changing the filter or removing the housing it removes all that oil that is needed for initial lubrication.

[@alanabt2494]

hello I have watched your video which is very interesting but after doing several searches in the bmw ista repair manual it does not mention this re-priming procedure ???

[@HowToDoitright]

lena aubertin interesting. Well this is the right procedure. You can either follow it or ignore it and take the risk of damaging your car. Up to you. If you do some research everyone will tel you to prime the oil. Your car bro so your call bro

[@sushipoushi67]

The reason for doing this, is due to air getting in the oil circuit and you can very well spin a road bearing. It’s actually a TSB that started from the N55 engine

[@jdelatorUIUC]

Any advantage of doing one method over the other? I can't imagine the first one being the recommended method if the second one is a lot easier.

[@HowToDoitright]

Don’t matter. The outcome is same. I go with the easy one

[@abraham1019]

Awesome! This will work for a 2011 bmw e92 with n55 engine same way?

[@HowToDoitright]

Yes engines r same

[@lytleric]

@@HowToDoitright Engines are the same, but the battery is not. This method will still work, but there is a different cable that must be disconnected. I just did this on my 2013 E92.

[@malteserwfj]

What is the different cable for the E92?

[@pencilcups3088]

So i dont have to fill the oil filter housing with oil if im priming it because its basically doing the same thing? or should i do both just incase?

[@HowToDoitright]

now you dont have to fill it but i do it as its a safe practice to do so. remember even when you are priming your oil pump may take some time for the oil to go in to oil filter and then distribute to engine so if you do both you are much safer. i recommend both but its personal choice.

[@shhhpark]

ugh my 2014 428i's engine just seized after an OFHG replacement...I suspect the shop didnt properly prime and now I'm screwed since they wont admit to fault

[@aimized1460]

Jesus Christ that’s so messed up to hear m, my sincere apologies

[@benten6301]

I will have to try again and prime oil. I can not remove the 2 plastic hose that crossed over to the manifold. I watched but your video shows far away not sure where exact to press and pull on these 2. I also could not unclip the top map sensor. I put a mirror to see behind, use plier to pull, I don't get the right technique it does not comes out. Then, I still have to remove the rear wire harness. I need help on the two hoses to the pipe, the harness to the rear, and the map sensor on top. What technique do you use? Because I had turn over , it ran then I shut down and did it 3 different times mighr have given me this problem. So my theory is to do the primimg to eliminate anything would help.

[@HowToDoitright]

ben ten watch my other video where I replaced the valve cover. It’s shows there how to remove the hose. You have to press on clips and pull it outwards while pressing. May need to pull hard. Watch that video.

[@benten6301]

Where did you get the oil prime instructions. Could you help us by posting where you get it on here.

[@HowToDoitright]

BMW repair manual

[@enayetkhan9397]

Should the engine still be primed when replacing just the oil cooler O rings? Thanks!

[@HowToDoitright]

I would just to be on safe side. Won’t hurt

[@ssingh2525]

Wouldn't removal of fuel system fuse/relay serve the same purpose as removing those plugs?

[@HowToDoitright]

Technically yes but I don’t know why BMW suggested this way. They designed it so there may be a reason. Not sure

[@fiatlux4265]

@@HowToDoitright could be because of added safety; someone may pull the wrong fuse/relay without knowing, which will then start the car. If you have all the injector connectors disconnected, that's a 100% sure way of preventing the car from starting, as you can't really mess that up.

[@alexr.9623]

I believe the reason is that method 2 needs to be done before you begin work. Since fuel will still be pressurized and in the system, if you performed the work, then used method 2, the engine might still turn over at least for a few seconds. With method 1 the engine even if there is fuel in the system, as you've cut power to the injectors. If you plan on performing the OFHG, use method 2 BEFORE you start working. Once the car stalls and will not start, you disconnect the battery and begin the OFHG procedure. When it's time to prime, the fuel system will not have enough pressure to turn the car on.

[@benten6301]

So as I try priming but engjne turn over, I got a train malfunction on dasb board. I hope this is temporary from unplugging battery and fuses.

[@HowToDoitright]

ben ten yes that’s normal. I got it too as you can see in my video.

[@dappa311]

Why not just disconnect the fuel pump fuse?

[@HowToDoitright]

You can if you 100-% sure it’s the right fuse. Otherwise you will regret it

[@NoEmotionsPodcast]

This was my thinking, like why are we in the engine bay?

[@dresito28]

Where did you get the instructions for the oil priming? You mentioned that BMW provides it, was it from a service center or online reference?

[@HowToDoitright]

Yes BMW service manual

[@dresito28]

Awesome, how did you get your hands on it? Also, I will be doing an OFHG replacement on my E84. For the "easy" option, did you find which cable was responsible for engine start and will this also apply to an E84?

[@HowToDoitright]

Andres Reyes I cant guarantee if it will work on E84. On mine it kills power to injectors. I would recommend before you start the job just disconnect power and try starting the car. If it doesn’t start it will work for you. The main purpose is for the car not to start and only for oil pump To come on to circulate the oil in the engine. Just make sure your oil pump comes on and that you can check by removing the oil filter just like I did. If you see oil in there then yes.

[@dresito28]

Awesome, I will do that...I'll do a vid of my E84 specific OFHG change

[@benten6301]

Will the easy second method works on F25 x3, 2014 n55 , 35i?

[@John-qc1zv]

I have a 2014 535xi. On my battery, I got a Red and Blue plug that I can pull. Any idea if they are the same ? The red one is same place of your black one, but the blue is down there.

[@HowToDoitright]

You can pull both. It’s safe to pull the cables from the battery.

[@John-qc1zv]

@@HowToDoitright I went to check again, and the black one is going in the fuel tank. I think it's likely to be disconnecting the fuel pump. Will give it a try. In the mean time, I wonder why you have a white plug and a wire on the 3rd spot, mine F10 does not. Do you mind checking where this cable is going into ? Just curious. Thank again for your help.

[@HowToDoitright]

@@John-qc1zv i would have checked for you but unfortunately I sold the car. Enjoying my Tesla now.

@@HowToDoitright I guess you have more battery now.

This procedure avoid engine failure after OFHG change ? Because I read lot of guys who get engine failure aftet OFHG change.

[@HowToDoitright]

Yes that is correct

[@sechszylinder8055]

@@HowToDoitright thank, I done the job but I didn't start the engine yet, I'm reading and asking on forums before doing a mistake. Strangely engine failures are reported only on US forums, 0 case on european forums (I'm from Germany) Some people says also the engine failure occures mostly on N55s which have external oil cooler. I have a square radiator attached to my OFH. Is that an external cooler ? Thanks

[@benten6301]

How did you take out the fuel injector connector? Did you just pull straight out or did you mention a flat head driver to push in the clip to release?

[@HowToDoitright]

ben ten watch this video of mine how I removed it. It shows in detail kzbin.info/www/bejne/aYWufJaolNtmqJo

[@luisvargas4577]

I came up with my own simple tool that allowed me to easily remove 5th and 6th fuel injector connectors nearest to firewall without having to remove plastic and metal bracings by making an L shape out of a metal hose clamp, then taped that together to a large sized L wrench torx key. I was able to use the tip of hose clamp to carefully push plastic connector tabs to release fuel injectors. The tool provided enough stability and strength for those tabs. I did have to pull on the wires to remove them since It’s a super tight spot in there and not much room for anything else. I made sure to pull upwards gently. I can remove both fuel injectors connectors in less than 10min

[@HowToDoitright]

Oh wow nice. You may want to make a video and share with everyone

[@benten6301]

Could I pull the fuel pump fuse which is 189 -20amp to purge and do it? I try pulling it but afraid I break the connector.

[@HowToDoitright]

Yes it should work the same.

[@benten6301]

I stepped on the brake and pushed start. Engine turn over. What did I do wrong. Am I suppose to step on the brake.

[@HowToDoitright]

ben ten yes but you may have not pulled the right fuses then. I suggest just pull the ones on the battery like I showed. You won’t break anything. It’s just held by a clip

[@benten6301]

Maybe there are residual fuel that keeps engine running. I don't want to take chances of waiting to burn out fuel then no point of priming oil.

[@HowToDoitright]

ben ten nope. There is no fuel that can supply once there is no power to the fuel injectors. It’s a procedure by BMW and trust me I did it. You have to kill power to injectors.

[@benten6301]

Question. Today I started the engine it started then died, it did this multiple times I tried with battery maintainer shows full. Any suggestions. I checked all plugs and fuses connected.

[@HowToDoitright]

ben ten check the cables you removed from back side of battery and make sure all plugs are inserted to the injectors.

[@HowToDoitright]

Did it work?

[@benten6301]

@@HowToDoitright it turns over , runs one second, then dies. I scan code fuel pump is not fault. Also, alot of code but no sensor code. Codes that's non related. I might have to remove air intake again and check fuel sensor in the back of the fuel rail. Do you have a probable fix to this? By way, I am not going to prime engine because I might break the connector if J pull on it.

[@HowToDoitright]

ben ten make sure you have enough gas in the car. Can’t suggest anything like this. Could be multiple things

[@benten6301]

I might called a mobile canic cost 38 to diagnose and 28 to not do it. TOTAL $70.

[@sonvfave]

Do we always need to prime n55 with an oil change??

[@HowToDoitright]

No but not a bad idea.

[@chewybacchus5918]

I do

[@benten6301]

It's been a month in my garage. I was able to turn it over after I replaced broken belt and oil -cooler gaskets. But I just want to I prime oil. However, I did not do it. Now. It cranks, starts, then dies. Maybe a relay to fuel pump under dash board. KZbin had a video but not on x3.

[@HowToDoitright]

Your belt broke while you were driving the car?? I winder if belt particles entered your engine. It’s a major issue causing damage to engine.

[@benten6301]

Yes. I removed the fan cowl, removed the crank pulley, I clean up the front seal and snap photo. It looks crisp and clean. So I think it should be fine.

[@aimized1460]

N55 is a complex engine

[@Matice21]

Prime the system when you do a ofhg change but you do do it when you change the the oil and filter....makes absolutely no sense at all

[@HowToDoitright]

When you change the oil filter there is no oil in the oil filter at all. Turning the car on the car will struggle with no oil very very short time maybe seconds but it takes milliseconds for engine parts to get Wear and tear without enough lubrication. Yes your engine won’t die but it’s good and safe to prime.

[@Matice21]

@@HowToDoitright this process involves cranking the engine over a 10 sec span and you just said that it takes milliseconds to wear & tear. This process absolutely defeats the purpose of “priming” just because your pistons move up & down & perhaps does even more damage than just letting the engine run to circulate the oil. I asked my former roommate who just started working for bmw over jus a year now & he said he never heard of that process & have done that job plenty of times without this procedure but let the car idle to let the oil circulate throughout the system which is common sense bcuz when you do an oil change, you’re supposed to let the car idle as well.

[@lmc333]

Looks impossible

[@HowToDoitright]

It’s not

[@shotamaisuradze9838]

Why not just pull the fuel pump fuse?

[@HowToDoitright]

In some cars the fuel pump fuse isn’t clear so it gets confusing. Also some fuses are on the rear battery side and fuses are non removable. Weird setup

[@allmycarsisbroke]

The high pressure fuel pump is mechanical and pulling the fuse won't prevent it from operating, and also won't prevent the remaining fuel in the fuel rail from being squirted into the cylinder by the fuel injectors.
