yes, but ? strange that it happens in the presence of increasing fumosit? and decrease in performance.

in fact,not ? that you have the turbine ko..........I give it a look
GALLO ORI + KESS V2 ORI
the whistle that you hear ? due to the exhaust completely empty, you have emptied both the precatalizzatore and both the DPF and the turbine therefore behaves as a whistle.. I usually precatalizzatore leave it always in order to avoid damage of the turbo compressor, of these changes I have made so many of them and honestly the first that I did I well I made the mistake of emptying it all with a consequence break the turbine and sbiellamento engine that remained high for the oil sucked to spondato all.. the fact is that if you don't want problems, you should rimontargli the precatalizzatore and insert in place of the Dpf with a straight tube, the so-called downpipe that is the original alpha.. cos? to avoid a nuisance of shit.. as for the power of your car or rolled ? went wrong or the machine does not make since? 200cv them must have eyes closed..
The patience and virtue of the strong..
then the system of the discharge of this machine is : precat attached to the turbine, after the dpf+catalyst. The prect of the left , have been removed dpf+cat together ( since they are enclosed in a capsule )
But the reason for which you can donneggiare the turbine if there is the precatalizzatore ? I thought it was better if the drain is******
According to me, the whistle and give some sleeve half broken .. or the link creppato between the turbine and the precatalizzatore
Because; an engine like this could not make it ? Or that it was the turbine, or if the compressed air that comes out somewhere before you get to the cylinder , or the map to hurt after the removal of the dpf.
To be honest, the engine is hot ( after 30-40 minutes of pull at maximum in the mountains ) you can hear a ticking ( tic-tic-tic ) from the engine compartment especially in making a steep climb starting from low speed in 3rd,so arriving at 1800 (pair) the rpm sticks to tichettare .. ****llo of sound is very perceptible, very clear .. just lower the window. I don't think that it is the injectors xke work on frequencies that are very high and not feel the tic-tic..What can be according to you ? tappets ?
I look forward to that I get the hw so here reading, thanks to all
I don't know what to think.. too much confusionOriginally Written by Backgroop
I tell you from experience, in fact I have a fleet of cars Alfa romeo 159 2.4 jtdm 210cv in the service will be about 120 and problems with this car come out of it are always new.. one of the many, and the breakage of the engine valves due to the malfunction of the injectors or excessive fuel injected with the consequence of breaking the engine.. I personally would advise you to leave the precatalizzatore to avoid facie leakage of the exhaust gas, which consequently result in increased rotation of the impeller of the turbocharger with a slight back pressure at the exhaust.. the valves swirl if you can delete them all..
The patience and virtue of the strong..
You're just giving advice all the wrong.
Remove the precat leads to rupture of the turbine? But when ever???
Remove the precat considerably lowers the temperature of the turbo, and, therefore, prolongs the duration.
Also on the 2.4 has a substantial increase in low rpm, as the turbo has a response pi? ready and ? pi? fast rise of pressure.
And the downpipe is not ? the straight tube to replace the fap, but ? just the semicurva to be put in the place of the precatalizzatore!
Then Sighline as I have suggested already? others read the current map that you have, just a mpps v5, and put it that we see if there are any errors.
Then check the turbo and maybe he has problems, and finally put safely to a downpipe, empty in the place of the precat, that helps you and that's it!
Hello...so...the first thing I advise you to buy the interface mpps v12 (also here on the site) and retrieve the file that you have now in the ECU...
I if I were you, I would make the effort to disassemble icolli suction and remove the swirl (on the 2.4 ? frequently that they are eaten by the engine).
As regards the smoke, check that there are no sleeves broken, and that the mass air flow sensor is in good condition.
Go quiet that do not break anything to remove katalizzatore and prekat and dpf...these are just urban legends...removing the kat, dpf and prekat, don't do anything that facilitate the evacuation of the exhaust gases, and then recoveries also something in terms of performance. For the speech in one piece and the turbine and the other..do not break anything..but...removing the prekat, you are going to greatly lower the exhaust temperatures, and this is just FINE to the turbine.
Do as you suggest, remove the swirl, control sleeves, accurate, control mass air flow sensor, read the map, and put it...you look at it gladly
PS: go quiet that with the mpps v12 clone on the site you will not have any problem...I have lost count now of how many times I read/wrote my stylus and 147 of my brother
Quoto what mario says, but if we eat the swirl, as it happened to me to hear the noise of metal if you okay, off,
Conclusion: the new Motor!!!!
By removing the precat the back-pressure decreases and this helps.
The turbo works at temperatures ir? and low ? much more? ready.
I removed it on different 159 is 1.9 which 2.4 including my and always with excellent results.
