Thanks for your replies guys!!
Clarky,
I will give the MANN filter a go!! Then try an oil change also if that doesn't fix it. The oil I used is MB 229.5 approved, I believe the MB229.51 is for the models with a DPF, my WH doesn't have a DPF. I am also currently using CEM's AW10 its awesome stuff I must say!!
Bloke,
My WH has 235,000k's on the clock and I have disabled the EGR about 15,000k's ago.
roscoea26,
Does the FTC Decarbonizer work well? I also use CEM's CRD fuel enhancer every fill up and I also used there FOC flush every service (except the last change as I ran out) I also only fill up at BP or Caltex outlets using their ultimate or vortex premium diesel!
Hopefully the new oil filter will sort out the noise as I don't think its a big end as a big end would never go away!! Please correct me if i a wrong!! It may be lowering the oil pressure due to restricting the flow past the filter? Hopefully....
Thanks again for your replies fellas!!
