Great explanation sir,excellent job

[@muzzammildeen901]

Thank you so much for this excellent tutorial. My e90 320i has always had that cold start rattle and low oil pressure (5 years) and I always thought it was the vanos. I took the oil filter housing and cooler apart and found that they were both saturated with broken pieces of timing chain guides. Needless to say.. the check valve was completely seized. I did valve stem seals twice in the last 5 years (the valve guides were shot as well) I really think that this causes them to fail prematurely.

Thank you for your Great work and videos Do you have the torque in NM for the screws of the housing and cooler? Greetings Stefan from Germany

[@starchmed]

Great video, super in depth! Recently replaced the alternator, and had to remove the airbox as well. However, that small vaccum hose was very brittle and it probably broke while i pulled it out.. I tried to repair it with some cable insulation and zip ties, but its probably not 100% sealed. What sort of issues can I expect from it not being properly connected?

[@BimmerZen]

That vacuum hose leads to the fuel pressure regulator that is integrated in to the fuel filter. You can expect overpressure in the fuel feed line and probably rich idle and lean on the higher power requirement. Overpressure can result in damage to the fuel system.

[@starchmed]

@@BimmerZen okay, so for sure replace with a proper hose then😆 thanks!

[@jurkaa]

Hello, new subscriber here! I own a bmw with n42 engine that has same cold start rattle and I’m curious to ask have you solved this rattle issue? For example, my rattle is sometimes present, sometimes not.

If you bleed system coolant Do you need to unscrew the oil cooler screw ?

[@jeromegabriel1256]

Hi! I'm actually going to change soon my oil filter gasket and oil cooler gasket cause i'm having the same oil leaks on that part and also in the cooling system. But do i need to change the coolant system since it has now a bit of oil in it?

[@e30_lad_ireland]

Hey N42 Guru! Great video as always, thank you! Do you have any idea how old are those gaskets or how many motor hours done before they become so stiff? Btw, I see you use use some nice hardware like Milwaukee! Fancy to make some content for us of it maybe in the future - this would be also interesting. Take care! 🙌🏻

[@BimmerZen]

Thanks! Those gaskets are at least 11 years old. I own the car from 2011 and i haven't changed them until now.

Hi there, quick question on replacing oil cooler gaskets, there's 2 coolant pipes below going into that black plastic fitting, my n46 320i e90 has some corrosion on the slimmer pipe. Do you have the part number for those pipes or know exactly what those 2 coolant pipes are called?

[@NikolaHetfield11]

Awesome content as always! One question about intake rubber boot. Is there a rubber ring between boot and mass flow sensor? I have that on my car, don't know is that an oem, or somebody replaced that with aftermarket.

[@BimmerZen]

If memory serves me right, there really is a rubber ring there... i think it's OE.

No need. You might have to top of the oil after the job.

[@ezrinosman]

did you drain the engine oil and coolant before this job? im planning to do this too but not sure if the oil and coolant need to be drained. i hope not so it can make the job more simple

[@BimmerZen]

You dont need to drain the coolan or oil.

[@KhataarFelMataar]

Thanks for this video! Are you sure 10nm is correct for these bolts? I bolted mine to 11nm.. and its leaking again. I did clean the sufaces and replaced with a new gasket. On some forum I read people are torqing to 22nm and the issue was solved for them.. Is yours still holding up?

[@BimmerZen]

The documentation states 22 Nm but also M8 bolt. But the bolt is infact M6 and those are usually 10Nm. The seal is inside a channel and is sandwiched between housing and engine block. I dont think torqueing the bolts to 22nm will help much with compressing the seal. but you could try tho. Mine is holding up so far, but I do not drive the car daily.

[@KhataarFelMataar]

@@BimmerZen Thanks mate for your reply. I'm going to redo it and make sure the housing surfaces are spotless. All the best!

[@mr.matiss]

Does your gaskets hold the oil well and it does not leak? Because I've changed the gasket like 2 times and it still leaks about a tea spoon per half year. So I wonder should I change once again but this time in addition to new gasket use some liquid sealer that suits the purpose? Could you share your opinion?

[@BimmerZen]

I'm not having any issues so far, but I don't drive the car daily anymore, so I cant be 100% sure it doesn't leak... I don't recommend using any kind of sealer or silicone on the oil filter housing as the excess silicone will break off and go past the oil filter and in to the engine and clog oil lines.

[@mr.matiss]

@@BimmerZen N42 engine is my daily choice, so I'd be happy to stop this leak. If I use some sort of strong, meant to be used for engine gaskets sealant and use it just a tiny bit to stop the leak. Would you still think it can get in to the engine? Also I believe there is positive pressure at the inside of oil housing that would push any sealant outwards. If you still does not recommend it. Should I just keep buying new gaskets until I get the one that fits perfectly?

[@KilliKonKarnage]

Hello, what can i clean the mating surfaces with. Brake cleaner is okay? I was worried about brake cleaner going into engine with oil. Should this be a concern? Thanks for the very informative videos.

[@BimmerZen]

Sure, you can use breakcleaner, just make sure you wipe it off and you're good to go. It evaporates anyway.

[@KilliKonKarnage]

@@BimmerZen ah okay that makes sense cheers

[@dyzio8034]

Hi,do u know if the gasket between the oil cooler can be the problem with oil mixing in the coolant reservoir? I’ve looked under the engine oil cap and there’s no sign of that there is any water in the oil but somehow oil gets to the coolant :/ . I don’t think it’s a head gasket , maybe there’s something easier to fix ;O My engine is n46b20a

[@BimmerZen]

That gasket is not sealing oil/coolant. It could be the oil cooler itself. You can probably test the oil cooler.

[@dyzio8034]

@@BimmerZen I’ll get one from bmw tomorrow and probably change it next week and after change I’ll flush the coolant so I’ll see if it helped , if not will it be the head gasket? Or there is something else what can leak oil to the coolant :/

Wow. This looks super easy to do. If that is the case why do some dealers charge upwards of $600-700 for this work?

[@BimmerZen]

It's easy on the n42/n46 engine, but a bit more involved on the m54 engine. Perhaps the quote is for the m54?

Hey, I have a problem with the same engine. The 3 mounting screws in this oil filter base cannot be tightened. They rotate. I took it out and it was a wound piece of aluminum. What should I do to thread the screw onto a larger screw?

[@BimmerZen]

Helicoil thread inserts is the best option. Just make sure that no debis go in to the engine oil channels. kzbin.info/www/bejne/Z2qZmn-hfcdjaKssi=S1XbXy6BEPR0bD1p

@@BimmerZen Thank you ! We can always count on you :)

[@BimmerZen]

And let me add this: I"ve seen incorrect torque values (20Nm) in the manual. Correct tightening torque for these three bolts is 10 Nm.

[@Rea-per]

I do have to ask. I've watched allot of your videos but you've never addressed the crank position sensor. Ive done all the other things on your channel. But nothing to find on a n42 engine

[@BimmerZen]

I did change my crank position sensor when i was trying to diagnose long crank start (kzbin.info/www/bejne/b6akfKFpZthji6s) but i haven't made a video on it back then... You basically need to remove the intake manifold (kzbin.info/www/bejne/q3OaaKyhq8ton6s) to get to the sensor.

[@Rea-per]

@@BimmerZen thanks so much! We burned some midnight oil to get the intake off. Actually removed the steering backed and bottom plates to get to the screws on the bottom of the intake. Struggled allot because we where missing allot of tools. But everything is working perfect now! Started with the valve seals, removed the head, cleaned it, surfaced it, new valve springs, then chain, replaced the coils, waterpump, cleaned out the double VANOS, accidentally mixed the connectors of the 2 VANOS actuators, that came with a heep of trouble. Did the belt, tensioner and dynamo. Filters fluids sensors ccv everything has been touched and replaced right before the 250k mark. Now focusing on the undercarriage, replacing everything with new. I really love this car (E46 316 1.8 touring 2003) and your channel helped me love it more. Its an intense car and engine to work on, but with your support it is a wonderful adventure! Thanks so much

Could oil in the coolant be a result of this gasket going bad? My coolant is like a caramel milkshake.

[@BimmerZen]

No. Does your coolant level change? Probably just moisture in the oil from short distance driving in cold climate... Here is an example: m.kzbin.info/www/bejne/aoaQZZ6Bjd-ZrcU

[@FlightAce100]

@@BimmerZen No coolant level change and not a cold climate. No coolant in oil, just oil in coolant. I've done some research and oil coolers seem to be the common culprit so I've bought a full gasket set anyway.

You might have clogged oil lines causing high oil pressure at the oil filter housing. I recommend you remove the VANOS solenoids and check if they are clogged. Also take a look at the bores and oil holes in the cylidner head where the solenoids are. sometimes you can actually see there are debris stuck there...
