The problem of butterfly valves on the intake manifold Alfa 159 150 HP

[jared_poe]

Hi everyone I need an opinion: last week we lit a failure on my 159, a check is made in the workshop they told me that the problem ? on the butterfly valve (the plastic ones), located on the intake manifold, it seems to me that the call SWIRL.
Given that a colleague of mine on the same car has spent around 2500? for the fault of those valves which are separated and arrive on a piston, I would like to know if you have any advice to avoid this.
In these cases ? fitting better metal ones or just remove them and change the map?

[magi1984]

if you don't want to spend anything toglile, if you want to spend some money, put it in the metal

[rego88]

I have a 147 1.9 150hp, the same engine.... on my swirl I deleted.... ? was a ammattimento.... I had to disassemble the fuel pump, a lot of things.... after that I pulled off the manifold.... edited, removed the palette, attappati the holes and then I put under the motor of the swirl ******.... without anything connected ? them' and not bother.... but' I in diagnosis nn I had errors, I don't know how do you get errors....

[mecdoc]

togliele and put the caps I usually do so? and I have no more trouble

[jared_poe]

what kind of plugs should I put? then I have to change the map?
thanks for the replies guys :D

[rego88]

no no... no map change!! just leave the motor plugged in....

[blackwolf76]

The same change that is also on the mercedes CDI since 2000.

[mecdoc]

1448io I make them this size

[tezzero]

I confirm the removal of the butterflies with motor connected..no error and no map

[Team electronics]

I confirm no error and the change of the map

[jared_poe]

thanks for the replies guys, mecdoc I can not download the file why? I recently joined, you can send it to me via *****?
Instead, if I remove only the butterflies without attappare the holes, there are issues of combustion?

as required by the regulations and is absolutely forbidden to be send by registered users in the forum with certain system material of the same forum,the sanction to ban both are completely user otherwise would not make sense, the restriction applied to new members.

Sorry, I thought that in this case there were problems because the file had posted just for me to see, anyway it doesn't matter to me I explain here if you can.

[jared_poe]

according to you, if you leave open holes on the intake manifold,which among other things is put under pressure from the turbo,there are no problems??
the combustion problems are the last of your problems.....
however, for writing so I think that you have not understood well how to do....or pu? be that I have not understood anything...
No No most likely the problem ? that I am ignorant on the subject, can you explain to me how to make the change, and since you're at it, tell me what problems I face if I leave it open

[jared_poe]

Thanks Munro for the explanation ;)
You physically as you do to close the holes where before there were the palette? Take a bell?
The file that I posted mecdoc I can't open it why? I don't have enough messages, you can scrivermele qu? the measurements?

[blackwolf76]

the streets + short and simple are two. Or are the caps to the glass, of the type that are located in the holes of the blocks of the engine of a specific measure of the holes of the pin valves, or you thread the holes and is screwed a bolt or a tapered plug. Of course, in both cases, the outside of the caps will put a bit of silicone paste.

Lately, I did a couple of mercedes and I used bolts 14mm.

[jared_poe]

am I wrong or the holes where the palettes are not circular?

[blackwolf76]

Maybe write Arabic.

Don't have to plug the holes in the blades, but the holes of the pivot of the vane. It seems to me that Msport just above is very clear.

excuse the question, but are you sure you do this work alone?
look at that, you have to disassemble a beautiful p? of stuff , including distribution, for what little evil, but as far as the change of the manifold if you caxxate risk of dropping the engine , if you end up with something in the intake pipes

Quiet the do I do I do in the workshop ;) it was just to understand how to make the change, however, munro now I finally understood, I had not seen it taken apart and I thought that the caps were put in the place of the palette... thanks guys, you just do the work maybe place the photos

[jared_poe]

are electricians in the workshop iveco, we have to do with different engines ;)

unfortunately my work does not only concern the engines ? all the rest of that ? a casino...

Not ? to know the facts of your own, but with what you enjoy?? Air system?? Abs?? Brakes??

Alias caps melting!!! ;)

closed off the topic, thanks.

[checcosassu]

or you could put the collector of the 150 hp euro3 without valves swirl

[sportknight]

sorry,better to disassemble the valves and saw the post,right?cos? it remains part of the post as the cap

[blackwolf76]

which post do you want to cut???

The valves are in communication with one another with a stick, while the individual valves have how to post a metal plate with fixed above the valve in plastic, as well as the bushings that rotate in the manifold.

To resolve, if they are not broken, removed from the motor and the fixed or otherwise (the ideal solution) disassemble the manifold and remove all, and in the holes of the bushings, put the caps fuzxione used for the blocks... I seem to have a diameter of 14 or 15, to the limit you can spend a drill bit and make them accurate to the plugs..

[James]

does not work more clean by changing the manifold with one without swirl

[blackwolf76]

but what you have to pay... and pay, the caps cost 2 euros all;)

[checcosassu]

no saw nothing :)

[michele30]

can it be that with this problem to the valves, the machine will put us a few more to go?
why? I have a customer that complains of this problem.

[checcosassu]

you could also impact power

[sportknight]

Of course, it also depends on them

[marco]

I wanted to ask a question, but if the swirl take it off in the map, the butterflies I have to physically remove?

[hyrosat]

it seems to me you can remove or leave them open from the ecu, however expect the advice of someone more? expert I had issues with the swirl on my manifold 3 were broken and they were metal

[marco]

ok, thanks a diagnosis of what it gave you?

[blackwolf76]

The important ? rimuoverele physically, being that sooner or later they break and they always end up in the engine, causing serious damage. From the map it would be appropriate to togleirle, but when they are in good condition to avoid disassembly.

[hyrosat]

even why? I seem to have figured out that if you take but you leave the actuator plugged in the car no errors

[marco]

removed intake manifold, but the butterflies are in good condition the remove and remove from the map?

[blackwolf76]

I recommend you to remove them and leave the motor connected. It is a matter of time and you'll go anyway, with the same routes and the risk of breakage to the engine.

[marco]

thanks for the reply but if I leave the motor connected to the I have to change the ecu?

[blackwolf76]

not c'? need... if you want to do it ? for your care.
