Cleaning the turbo oil feed banjo bolt on T-Jet MultiAir engine - Alfa Romeo, Fiat, Dodge, Chrysler
HTML-код
- Опубликовано: 25 авг 2024
- The turbo oil feed banjo bolt on T-Jet and MultiAir engines has a filter mesh like many other cars have too and it's not mentioned in any service schedule. Over time it can start to limit oil supply to turbo causing premature failure. Found in my Alfa Romeo Giulietta, and many other turbo engines by Fiat like a Dodge Dart

Thank you. 99,000 miles on my 1.4 turbo. Until today, I never knew about this!
Changing this bolt should be included in standard maintenance operations done by the dealer, but I wouldn't be surprised they don't even know about it.
NOthing in the manual, also for the multiair filter , seems like they want to destroy the vehicle
Holy crap! Amazingly useful video, thanks from the UK 👍 🇬🇧
Thing with these turbos is that the oil line is often very close to the turbine housing. If you drive hard and turn off the engine immediately (or the start stop does), it'll cook the oil in the oil line...
was able to get this out after spraying the base of it with penetrating oil and leaving it a few hours, and lightly taping the head a few times with a solid metal tool.
It looked horrific inside, after 120000 km with no cleaning, and also spent a fair bit of time trying to clean the gunk from the inside screw threading, and making sure there was no hard bits that fell off in the turbo oil restrictor area just bellow the screw. Replaced it with a new one, so I hope it will prolong the turbo life somewhat, even if it was done so late in the car's life.
It is even better to drill that hole, in order to remove the small filter that is inside. That way you solve the problem with the oil supply to the turbine forever. And of course regular oil changes (prescribed) after that. Greeting from serbia!
Great advice. I might do it next time
Followed that advice (oddly mine didn't seem to have a filter), gently turned drill bits of ever larger sizes in the bold by hand (removed so much more than brake cleaner alone), started off with about 3.5mm diameter and ended up at a 6.5mm drill bit. Turning by hand removed so much baked on oil.
Think I'll have to take the oil line off at some point and clean or replace that too.
@@robstebbings3556 maybe you should do a few oil changes every few hundred Km with a cleaning treatment like Liqui Molly to get that motor clean. Did you clean the MultiAir filter while you were at it? That gets blocked too. I have a video on it as well
Great stuff, thank you.
No problem. Check out the video on the MultiAir filter as well
Just checked my 1.4l Renegade, no filter screen in the banjo bolt.
Some don’t for some reason.
Never heard this before...thanks my friend i will do it soon.....1 question where this cleanout helps ???
It helps your turbo maintain oil supply so it doesn’t blow up
Thanks. I manage to remover bolt without removing the cover. I just wonder about those 2 holes in that bolt. I supposed the oil have to go through one of them and it have to be aligned with oil pipe. Wonder if the is a risk to not align them properly?
@@rasier101 just get everything clear
@@TheEddysGarage As well I notice it fix my whining turbo noise and probably prevent damage so huge thanks again for this video. Couldn't find any solution for this worrying and annoying noise and it is completely gone now. This bolt filter still blows my mind. Seems like no one knows about this. Wonder how many more things like that in our Giuliettas xD
@@rasier101 good job 👍.
Thank you for this video im looking forward to cleaning it when I change the oil of my mito 1.4T multiair, but does the position of the banjo bolt when you re-screw it matter ?
Just wondering if you have the answer for your question?
@@filipsmorozovs625 it dosen't matter but make sure you use New aluminium washers and tighten with the oil line straight and not too tight
@@enidra5388 sorry, do you know the exact size of the washers needed for this banjo bolt?
The mesh isn’t present on a 2013 1.4T Multiair 500 Abarth. Just checked mine. Not sure about newer models.
That’s a good thing
1.4 t-get also has similar bolt down, to the oil filter housing. Does it worth it remove and clean?
It isn’t going to hurt
Does it come with a washer which will need replacing?
What are the torque setting when putting it back?
I reused the washer. I don’t have torque settings for this sorry
@@TheEddysGarage thanks
Why a filter at that place? It blocks the flow. The oil going to the turbo is allready filtered by the oil filter🤷 or do i miss something? I could be wrong🤔
Just Italian car things 🤷♂️
You can clearly see the amount of debris there that was trapped by this banjo bolt filter. Without the filter all that stuff would have ended up inside the turbo bearing section. You have to understand normally the entire engine only has one oil filter. So whatever impurities there are in the oil circulation do not get filtered out before the feed reaches the one single filter. The turbo bearings are the most delicate part of the entire lubrication system. That's why they have their own filter.
I can't find any information on the 2.4 multiair regarding the oil screen. Is it only on the 1.4?
Not sure sorry
Ok thanks
Great! I didn’t know this filter existed! Did you replace the washer or did it torque up OK?
I just tightened it up because I couldn’t get a replacement
@@TheEddysGarage any leaks since cleaning I wouldn’t mind doing this to mine Just can’t get the washers
@@adyg8221 no leaks at all on our
@@TheEddysGarage thanks mate 👍
Guys you should also check the whole pipe as I've seen videos where it's blocked with the gunk carbon stuff. I'll find video link and post it.

How many miles does your car have and how often do you change the oil?
90,000km on the car and the previous owner serviced it by the book.
This applies to 1.4L Renegade too?
Yes if it is the same engine. Check the MultiAir filter too ruclips.net/video/s5ZcjKI6Wys/видео.html
No filter there mate, the filter is in the other side of pipe.
It’s pretty clear that there is one in the top bolt because I clean it and I mentioned the lower one in the video as well.
