Pulled the manifold off one of our vehicles yesterday as the EGR valve was making unusual noises and a mate had advised me to remove and clean the inlet manifold while I was on the job.
This is what I found! Lots of carbon build up. Vehicle has nearly done 110 thousand kays.
Makes you wonder why an engine would have such a thing fitted to it!
Hardly clean burning.
Cheers, Mick.

The noise was abnormal Mick.
EGR valve was leaking.
