brera 2.4 jtdm unusual sound from the turbine [file included]

[blackwolf76]

The filter is located in the fitting that connects the hose to the engine block.

I for prevention every time that I have to disassemble some of these the remove always, by fitting a simple fitting diesel with holes larger scope unlimited. In this case, the lubrication ? assured, and certainly that type of problem is not the avr? pi?. Although lately I've been unfortunate in a connection like ? finished a piece of motorsil left in the engine from somewhere? those who which to me anyway is quite fitting and ruined na turbine of a 147 140cv.

For prevention here do I mount a turbine, I always do a dry oil in the lubrication circuit with a blower from 1 bar that I have the car built in that free of any impurities? and do 2 schiavettate the power to purge a bit of oil that may have residues corboniosi, then the horsemanship, the other 2 sxhiavettate to fill the circuit and go and never had a problem, the current turbine 150, which I mount on the 120 hp is a slight whistle from 0.1 to 0.4 bar only cold, which then attenuates much when the oil is heated, what more? that normal

in fact, my behaves in this way, in the cold, whistling slightly then as it warms up it feels less...

[tidus1985]

the 1.9 are famous for a slight howl of the cold, but up to 0.3 0.4 bar, as well as the part with the push to chill and then, however, over the covers, the noise of the air sucked by the impeller

Thanks to all for the answers..
Munro, the filter circuit of lubrication, and it was checked when I changed the turbo

Yesterday I was in the shop and I did remove the precat and the sleeve turbo-IC ( it was a bit fesurato saw that he was touching a bolt of the form of the turbo)
I did 20 euro of blue diesel smoke and it's gone .. in spite of this, the whistle still persists..

I realized then , that smoking is neither a result nor the cause of this whistle...

Having checked all the points 'critical' that could cause the whistle the only place to be reviewed, and the tube luca stanca .. which according to me it was mounted wrong

Also because I started to feel 'I'm whistling at a time when I've removed the fap.. then turning with the straight tube

I I were you I formalizzerei too if you've checked all of the system. I know of a car of our customers in the workshop that whistle from the na life and are not ever stops.

So much to say lately I ? happened na croma 150 that has had problems with the swirl, so I had to remove both manifolds, intake and exhaust, and then also the turbine that I have checked and verified in all its parts do not observe any anomaly, at least from a visual point of view. In the context I also defappato and increased a bit of horses and I can tell you that whistled before smontassi and whistles is still very evident even with the engine at idle sometimes, and in spite of all traveling that ? a pleasure without any worries of several thousands of KM.

According to me what type of whistle ? caused by some slight ripple of turning the turbine, or by the blades of the geometry adjust evil that create a flow of air crash that does effect a whistle, accentuated by the removal of the Fap that attutiva substantially the same whistle...
