    Default Z19dt bad noise maybe turbo?

    Hei. Well last night after revving 2nd fear over 3500rpm and not really warm engine, I never do I just had music and didn’t notice, there is a strange very loud sound, sounds like very loud turbo noise but it’s all the way from 1200 rpm. I can’t hear it only on idle. No black or white smoke though just a bit fried oil. Look really black and fried. Also slight loss of power, obviously something isnt working properly. Z19dt with 310.000 km. Last oil change was around 8000 km. Any ideas before I go to the mechanic? I just put some fresh oil in the engine didn’t take much. Car is revving fine but more the rpm louder the sound... like I put an huuuge turbo and the sound is now x10 louder...I would describe it like someone in your ear is making ouuuuuuuuuuuuyyy and getting louder as the rom goes up

    update
    big lose of power, engine revs very easily all the way which doesn’t feel normal, but like nothing is happening to the drivetrain, also black juice in the exhaust pipe and after revving found marks on the street of thick black powder thing. On low speed up to 2000 rpm feels like normal just when u push pedal the engine like revs freely with no results other than the loud sound

    Can the crankcase breather be a the problem? It’s wet and oily around while everything else is dry around there

    Oh, the post hasn't been up long but either way if you want help from the net your going to have to start looking at the engine closely and look or leaks. Plugging it into a proper reader to see what's going on might help to, that soot is unburnt fuel so whatever's going on its over fuelling. As its a Signum i think it has a DPF so could be trying to regen.

    Check which engine your on about as well as the one in your details does not exist, Z19DTH or Z19DT

    As Dog has said, black soot is unburnt fuel so basically car is over fuelling and not burning it off properly! Could be DPF but with the noise your saying it’s making and loss of power I would say Turbo is more than likely on way out and isn’t putting enough air in to burn fuel.

    Is there any smoke at all?

    could you take a video of noise?

    Im sure others will view and add their thoughts shortly...

    You need to add more info to help us help you.

    The noise is it a screaming sound?

    Is it worse when its cold?

    Are there any diesel smells inside the cabin?
