159, 1.9 Jtdm heavy ticking noise
Hi everyone, hope someone out there can shed some light on this,
My 159, 1.9 Jtdm has developed a heavy ticking noise/knocking sound , you can hear it inside the car, and sounds like s**t on the outside, The ticking is linked to engine speed.. seems to be loudest between 1000 - 2500rpm. The sound developed slowly and is getting stronger over time,
Could it be the injectors? or tappets/hydraulic lifter??? it is blowing a bit more smoke than usual. its driving fine just the noise is ****ing me off, it is due for a service. I have had DPF remove, EGR blocked, ECU remapped, belts and chains replaced.
would just like to know what you guys think it could be.
Any ideas most welcome!!
