Hello everyone, any sorry for ur time I posted a video here months ago about weird noise under the hood (passenger side unde the motor) , and i tried to record it with som poor video quality, Now its much persistent and louder so i took this video , and i hope its clear this time It starts when the engine kicks in and stays at idle, and go away when i press the throattle. I tracked it to the passenger side just beneath the motor. I visited couple of mechanics and they offered to take the motor apart as they cant figure out what is it coming from exactly Any help will be appreciated and thanks every one
seems too young for engine problems. maybe start with the egr circuit and intake manifold. does she burn any oil?
Timing chain, that runs between the crank shaft and the two cam shafts at the top, is in there, behind a cover. it has tensioners and what not. I would hold off; the cure could be worse than the condition. Timing chain cover seal and reinstall is VERY tricky, and in tight quarters. Just monitor for a while longer.
Mendel could be on to something. Some cars with long timing chains use hydraulic oil pressure to apply tension to the timing chain. I did one many years ago and all it was was a piece of dirt clogged a small orifice not allowing the tensioner to work.
