DO NOT change multi air unit without using the specialist tool. You stand a VERY high chance of bending the valves in the cylinder head. Then it will cost more money to put right
@@itsaboutcarsyt If you dont get the buttons underneath the multiair unit perfectly in line with the tops of the valves in the head. If you push it down on a slight angle, the “buttons” can push past the valve stems and operate scraping down the side if the valve stem. I have learnt this the hard way😫😫. The tool takes the pressure of the valve springs so the unit can be sat perfectly flat to the head without any force to push it past the cam.
@@Dering79 so you mean the little pushers on the downside? Those seemed to be so light. Never imagined they could provide pressure to the valves without the engine running. The Alfa shop recommended me to just go very easy on the multiair, not pushing it but screwing it in as even as possible. I guess the best way is to lend the tool somewhere to be safe
@@itsaboutcarsyt Because the multiair unit doesnt need timing up, those springs are tight against the third lobe of the cam shaft. They are light with no oil in them. It is when you fill the unit with oil and run the engine that the damage happens. And if you dont take the pressure of the springs you cant guarantee they are lined up with the valve stems. Because those little “pushers” are in essence a small hydraulic cylinder. Which if not seated correctly will just rub up and down the valve stem. Fluid cant be compressed so they just bend the valve then it is a full head off job to replace any bent valves.
@@Dering79 that's good information thank you. I was either lucky or you were extremely unlucky back then... Hopefully the viewers will read this and decide what to do for themselves
Very nice exploration and information(it's a especial tool to install it,that help to keep the spring tension till you center the unit to avoid damage to your bolts,$220 dlls kit,engine actuator compressor PQY..
Excellent video! I have the DTC P1069, too. I was assuming it was due to the multiair. Now, with the syntomps you mention, I am sure that is my car issue.
good job bro. i guess I've been super lucky i use castrol oil in mine with no problems so far and i have to admit ive never replaced my multi air filter, my milage is over 100k... think i will do that as my next task. but i do service the car myself and regularly so i have been lucky. also thank you for revealing where that oil leak from the crankshaft vent is coming from.
Just going to leave this here even though it's an old video, but after replacing the unit you should calibrate it using special software, like multiecuscan. Nobody seems to mention this, but you should actually do that after an oil change as well.
The reason Selenia is recommended is because of a commercial arrangement between Petronas and Alfa. It’s not really special. The key is keeping the oil clean and using a good quality oil. The Motul was not responsible for the MA failure. In the US market, they recommend Pennzoil, which is the same as Shell Helix Ultra.
Heard a lot of similar opinions by now. Did exactly what you suggested, am the third owner though. What the reason for MA failures is will forever be a riddle I guess.
@@itsaboutcarsyt It’s no riddle. Poor maintenance results in carbon particles blocking the filter in the head and starving the unit of oil, and carbon particles blocking solenoids in the MA unit.. Some failures are electrical failures of the solenoid, that’s going to happen regardless of maintenance regimes. Early ones sometimes had a thread fail on the plunger that is activated by the cam. That was a manufacturing issue, solved now and also not a maintenance problem. If anyone tells you only Selenia, ask them what is special about that product and what failure mode does it protect against and how.
@@itsaboutcarsyt Your engine was not well maintained - the colour of the innards tell the story of far too many kms between oil changes. You were also not nearly clean enough in your work - should be virtually surgical and especially careful to cover/block off oil supply passages in the head. One tiny little bit of grit in there and your new MA is toast.
Greetings ... I have a Mito 135hp ... 70000km ... I used that selenia oil and I used to turn on the engine light all the time ... I replaced the micro filler (in which I found a piece of cloth) 😬, cleaned the oil pump sieve and poured Motul oil ... I haven't had a problem for a couple of months, the car is running normally, like new ... the oil needs to be changed at about 8000km and every 30-40000km the oil pump sieve and micro filter need to be cleaned ... and Selenia oil disappointed me how much creates dirt
Yeah I hear lots of stories like this. I guess you can say there is no correct answer to the oil question, it's like a gamble haha. Never checked the oil pump sieve that's a great idea!
with the selenia I risked losing the module, after replacing it with the motul xclean the machine had no more problems. with low temperatures the selenia becomes too dense
@@fabiosini848 a few months ago, I talked to a guy who is an mechanical engineering at Alfa Romeo, and he was very clear when it comes to Selenia oil has Alfa recommend But I respect your opinion Since you have the car, have vou had any problem using the selenia?
For some reason I often see the turbocharged MultiAir units failing, no idea why. The NA MultiAir unit I have in my MiTo has been working for 11 years and hasn't even used Selenia all the time (Q8 5W30 C3 since the last few years) and it runs fine.
Maybe the pressure chambers are affected by the additional power due to the turbo. I can't tell what the problem is so far, since I haven't opened it and others do run other oils with no issues. An official statement would be great but since this engine is quite old I don't think we'll get that
Did you know that there is a turbo oil strainer filter, the white plastic mesh insert gets burned or disolved since it is no longer around (happens to several people including myself). When ordering a replacement, the white mesh is there and fully visible. I wonder if that dissolved plastic is able to somehow get into the multiair? The multiair oil strainer filter has a similar mesh, it does not dissolve or burn of. Maybe the oil temperature is temporarily higher on top of the turbo.
Very nice and concise can you please provide the crank ventilator gasket part number number And also part number for the rocker cover bolts? I've unfortunately snapped mines and need to get it out of there
Hey, sorry for the late reply. If you couldn't find it so far: here's a link to the website where I usually find out about part numbers alfa-romeo.7zap.com/de/mit/qz/145q36101000-010/101/1+10101-030+2-0/ However, the OE Number for the Crank ventilation gasket is: 14457880 The cover bolts: 55199486
Tightining up the multi air filter that hard is one of the reasons to damage your multi air unit simply..it just need to be tightened gently with a specific torque turns
I am writing from Hungary, using Google Translate!The car throws error codes P0302-98, P0300-98, apparently 3 cylinders are firing. I changed transformers, candles were changed. I dismantled the 3rd transformer wire as much as possible, there is no break. Multiair error?
what oil Brand you are using, could you please give me the name? I have a fiat with the same engine and I us ligui moli full synthetic 5w 30 . I'm always trying to get the best engine juice for this engine. Now what grad are you using and are you using full synthetic
what year is yours? mine is from 2010 and the same problem, they say that since 2012 they have modified it and it won't break now I have to replace it too an important expense for a small car that the FIAT of my country that is Italy has made a bad impression on us in the world ! thanks for the tutorial
hello can you tell me wher the oil comes out to feed the cam ive done my head gasket and now have zero oil coming to top of engine but it is pumping strong to top of turbo i think its failing to start as the multiair unit isnt primed ????
Hey man... Great content... A few of your vids actually helped a lot... However I'm hearing a ticking like noise, how do I know if it could be my multiair unit? There is no check engine light appearing.
Hi! Having cylinder misfires more and more often (P0300, P0301) and now the P1062 code is constant, can't use the DNA switch also. That's gonna be a multiair issue right?
Hi i have a punto 1.4 16v turbo.and a ratling noise.kan it be the multiair unit.i was thingking that my.pistonrod berings war gon.and i fixst them.but the noise is stil ther
hey, sehr cooles video :) bei dem fehlercode p1064 (Magnetventil blabla), den du am ende einblendest, reicht es da erstmal den filter zu wechseln? und geht irgendwas am motor kaputt, wenn man den fehler eine weile ignoriert und er ab und zu Fehlzündungen hat?
Hey danke :) Bei mir ist bis zu dem video nix gewesen, multiair Filter tauschen und eine Motorspülung von Liqui moly reinkippen bevor man den anschließenden Ölwechsel macht sollte die Zeit überbrücken können (habe ich so lange gemacht) Die Abstände zwischen den Fehlermeldungen werden von Zeit zu Zeit dann aber geringer
Hi. Can a damaged multiair flood the cylinder with oil? In my car, the second cylinder is flooded with oil, there is a spark before flooding, so the coil is operational and gives a spark. Thank you for the information. :)
But give me a oil with the full specs other than selenia. The others don’t have the fiat spec well they don’t here in Australia. I’m sticking to the recommendation of selenia KPE
Where do you buy your multiair unit? I have the same problem (i think) on my Mito 1.4 MPI Multiair Distinctive and I don’t know where to buy one except the Alfa Romeo dealer
There are different multiair units out there and i cannot say for sure if the process is exactly the same. If you have the 0.9 in the 500L it's a smaller component, but I guess your renegade has the same 1.4 engine as the Mito and therefore the same multiair component
Nice vid! On ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E7Tg5VEN7Xk.html you say T45 which is torkx, the bolts you show are Ribe bolts. A lot of Fiat / Alfa / Lancia's use them on the engine.
How did you loosen the shield of the vaccum pump? It has 5 bolts, but the lower bolt on the front side is really difficult to reach... did you undo the big hose?
Hi, my new multiair unit is in. Actually, it's nine RIBE M8 bolts and the torque setting seems to be 20 - 25 NM. This would explain why your bolts did break. I reused mine.
@@itsaboutcarsyt awesome ty sir, I was having trouble finding the info. Exactly the issue I’m having. Ty for the video as well the response. Have a great day my friend.

Are those Multiair units reiablel at the end or not?
At this point I wouldn't continue without someone who knows about multiair installation. Maybe you should grab the specialized tool to perfectly align everything. It's about 100-200 bucks and saves you from bending a valve as stated in another comment under this video. Otherwise you can maybe lend it from a local friendly Alfa shop, worst case tow your vehicle there to prevent anything bad from happening.
@@itsaboutcarsyt hi, danke für die Rückmeldung. Also alle Magnetventil der Sensor und die Zündspulen sind eingesteckt. Da dürfte alles passen. Aus der kleinen Kugel kommt auch Öl beim drehen. Der Motor dreht bis es nach Kraftstoff stinkt obwohl ich das Gaspedal durchgelesen halte
Try a different Alfa shop, maybe the one you went to is just rude.. don't know anything about the code you mentioned sorry. A quick research on the internet tells me it has something to do with your steering column
