BMW N52 Oil Filter Housing Gasket Replacement *COMPLETE GUIDE*

[@GP-ue5hd]

Hi, Great video, thanks. I'm a complete beginner but I decided to go ahead. I just went through the process and changed the 2 gaskets. But had unexpected issues that I'd like to share Old gasket were really broken, 15 years old. 1/ the middle length bolt is very difficult to reach, because the torx wrench and 1/4 to 1/2 adaptor were too large and ... too long. I used finaly a 6 pan classic wrench that is smaller and it worked fine. 2/ to prevent the bolts and wrenches from falling in the engine, I attached to each tool a rope to secure my work and I saved time. 3/under the air filter box there is a kind of one inch half sphere rubber support that needs to be readjusted when you put back the air filter. 4/ I emptied the the coolant reservoir in separate box to avoid to have the coolant leaking too much when I open the oil radiator. It worked great. 5/ best coolant temperature is 30 to 40°C, you can check the temperature on the hidden feature #7. !! make sure the engine is cool, that means you drove less than 3 minutes to avoid heating injuries. I didn't see the above in the tutorials, hope it helps, BMW E90 325I 2007

[@outofgasgarage929]

Number 4 is a great idea, I will do this too when I do this job, thanks!

[@pilotlars]

Excellent video. I'm replacing the seals on a friend's 2009 X5 and when I removed the thermostat hose I noticed the lip that holds the O-ring in place was broken off. The hose only costs USD 27+tax. Surprisingly easy repair, BMW charges around $850 for this. I could go into business for myself just doing that LOL.

[@evensisftw]

Thanks George, just finished this job along with doing the tensioner, idler pulley and belt. As a note, i lost a 250ml of oil doing this, which given how much come out, seems about right. Mine was hurrendous, hours of scrubbing getting all the caked on oil off. Pleased to say after a nice long drive, not a leak in sight! As always, your videos were invaluable - keep it up!

Great video, had mine replaced by myself 10K kilometers ago, and once again it’s leaking so will have to replace it another time. First time I’ve made the mistake to not flush the coolant before removing the whole part, and get oil and coolant mixed together into the engine ! What a pain to clean everything. So thank you for the advices with the coolant pipes and oil cap unscrewing !

Does the coolant go into the engine? Im worried now. I did this job and feel i have to change oil now

[@danielgonzalez2327]

@@AbdulHaq11901do you have to drain the coolant when you do this and bleed the system?

[@adrienlazac]

@@danielgonzalez2327 it all depends if you’ve have been able to managed to not mix oil and coolant while removing the oil filter housing. If you notice some oil inside the coolant reservoir, then your good for a proper flush of the whole coolant system. Same if your oil turn to a white cream such mayonnaise.

[@mattlesser7904]

[@mikedodd9294]

when you buy the gasket ONLY buy BMW or elring. They are the ones with the new formulation of the rubber and BMW has updated the part number. Yes its 4x the cost at the dealership but these gaskets never shrink or deform like the original formula. If the package does not say MADE IN JAPAN, don't put it in or you'll be doing it again in 25,000 miles. The best thing to come out of the BMW and Toyota partnership, gaskets that actually hold oil!

[@Asserti]

Elring 632.090 and not the 504.530 as I bought :p

Great job, its a good idea to make a video of the same job but on the N47, they are fairly more complex and have a chronic leak in the tubes inside with bad orings. I just did that recently.

[@GeorgeAusters]

Yeah a lot of people were telling me about it but I have zero leaks on my N47 👍🏻

[@LH17578]

Really enjoyed your informative video and all makes sence. When you started the engine was i hearing lifter tick?

[@TebogoMotlhale]

it might be a less messy approach to create your own cheap custom brown paper box container with soletape and have it fit snugly JUST BELOW the cooler so that the oil does Not spill all the way down dripping onto hoses and only be caught FAR away far below its spilling point ?

[@mshahid2898]

Top video on this issue with the N52 engine - if left it will leak oil and or coolant on the serpentine drive belt. So it’s fairly urgent if you have the problem. I would just add - ONLY use BMW genuine gasket to avoid it failing - the cheap ones are really bad so avoid them because you’ll be doing the job again in a few months - really. I also found that one of the aluminium bolts in the gap of the manifold can easily drop so I loosed it & put some bare copper electrical earth wire around it and then slowly loosened off completely - this of course held the bolt so it couldn’t drop - a bit like a copper earth wire lasoo. It’s a great idea for any bolt you fear may drop down into engine bay or is generally tricky to hold. This replacement is needed every 60K or less. Common issue solved in this Video. In the E60 you don’t need to remove the air box - but removing the fan gives you much more room to protect the back of your hands - good luck 👍🏼 & peace ✊🏼

[@GeorgeAusters]

Yep exactly what I said in the video!

[@mshahid2898]

Ahh did you.! I didn’t know you used the copper wire ‘trick - I skimmed though it as I’ve re-done it over lock down and 70K+ before it - every new N52 owner ‘should know this - 👍🏼

[@GeorgeAusters]

I have a magnet to retrieve bolts that fall :)

[@mshahid2898]

[@GeorgeAusters]

They’re steel not aluminium

[@waqarditta7297]

Excellent video, step by step, just what I needed and i'm sure others too. Would it be ok to apply degreaser to the engine components and jetwash it all to remove past oil leakage and debris?

[@GeorgeAusters]

Yes fine

[@philippe5249]

Have you heard about priming the engine before starting?

[@guitar007]

Perfect video! Thanks for sharing. My F10 has a slight leak on the cooler starting, so this will help to fix. I see you didn't drain any of the coolant first? Is that because the hoses are located high enough just to have not too much fluid in them? And I see u re-used the old screws? They are not for one-time-use?

[@GeorgeAusters]

Steel bolts are reusable.. it’s the aluminium bolts that are one time use like on the valve cover👍🏻

Great vid! How come on the n20 and n55 they tell you to remove the fuel pump relay and crank the engine after everything is back together - but people are not doing this on the n52?

I'm assuming that is to get oil flowing through the engine?

[@ShowMeWhatINeedToKnow]

@@GeorgeAusters yeah, but why is it not necessary on the n52?

[@Soravia]

Just drain the oil and put on towel on accessory drive belt, if you have a new belt. If your belt is old, use continental brand belts with ribs looking like running shoe soles. They have best traction to prevent belt slip. Tested on supercharger vs traditional V belts.

[@Soravia]

Continental Elite belts formerly Goodyear Gatorback belts.

Hey George! 2 questions for you. I flushed my coolant system a few weeks ago because the previous owner was running cheap bad quality green coolant, and I wanted to replace it with G48 blue coolant. When I flush it, there was some dark gunk in the coolant. I didn't pay much attention to it, but last Saturday I got a chocolate milkshake on my coolant reservoir and low oil warning. I diagnosed the issue to be the OFHG and the heat exchanger gasket. Do you think that dark stuff I found in the coolant when I flushed it a couple of weeks ago was oil from a bad OFHG? No coolant went into the engine (Popped the oil filter and all the oil there looks perfectly fine, plus the head looks good from the oil cap), just oil onto the coolant system. Is it ok if I just top up the oil after replacing OFHG and heat exchanger gasket? I'm dropping the oil pan in a month to change the gasket anyway, so I don't want to have to change the oil now and again in a month when I drop the oil pan

To anyone who undertakes this- worth buying an E10 1/4 drive socket for the bolt behind/under the manifold (the bolts are actually E10, not 8mm), if you strip that one using the 8mm socket it’s no fun. The 8mm isn’t actually the right size (but does work but can slip and round the bolt)
