ALL PLEASE BE AWARE……THIS GUY’s “UP A GOOD HILL” MAY CONSIST OF DRIVING ABOOT CRAZY ROADS IN THE LAKE DISTRICT….! IF HE INVITES YOU ALONG, THROW A SICKY……COVID 38 SHOULD WORK.
I'm a big believer in an "Italian de-coke" before the MOT as well. I'm a pretty gentle driver and I'm not sure it does the engine any real favours. The guy that recommended the Italian de-coke to me was a specialist diesel fuel system mechanic, his actual words were "so long as you put decent oil in it and keep it at the right level, you will do nothing but good giving it a run at high revs - ideally up a good hill!" The other thing that would be a good peace-of-mind check would be removing the EGR valve and giving it and the ports a good clean. I tend to do this every two years.
EDIT: I've a fairly early 4.3 without the watercooled EGR valve and bow to BigKevs knowledge on the water cooled ones - Thanks Kev!
