Hello drivers.
I need advice on jake brake noise. It's been 2 weeks...one day i have noticed my jake brake sound a lot louder than normal. So i checked for visible leak,holes, or disconnected exhaust pipe thru but everything was fine. Also i could hear air hissing sound when i let go fuel pedal at high rpm bet 1300 n 1500.
Checked air line for turbo but couldn't find
anything wrong.
if any of you had similar problems plz drop me an advice... appreciate
