Timing chain and sprockets changing.
I am in the process of changing timing chain and sprockets, engine has done 158k and the oil and filter have been changed every 6k.
Also changing oil pump chain .
Took sump off to aid process. Oil suction guaze was nearly blocked with hard carbon, every component is also covered in hard carbon.
I have decided to change the oil pump as its off.
All this black hard carbon is the result of EGR !
Looking for recommendations of the best engine flush to use to try and shift some of this carbon. Its never over in my land rover.

That is a bit scary. I had my timing chain done at 113k while a leaking fuel pump was being replaced. Garage didn't mention build up of carbon.

What sort of driving do you do? Many motorway miles or slower roads?

Do you use any additive with the fuel? I use Millers Ecomax with every fill up. My indie insists on using Forte flush at every service.

All sorts of driving long short medium journeys, off road.
Time on idle running winch.
Recently fitted a decat pipe that improved fuel efficiency by 15%.
Had Millers do an oil test in the autumn and that showed no issues.
This black deposit only shifts with macanical aid! Its never over in my land rover.

My experience is that the carbon build up is generally caused by the oil itself.
A while back, my father reported to me that his low oil pressure warning light was occasionally coming on (its a petrol toyota). Connected a pressure gauge, low and behold, oil pressure was practically 0. Sump off, and everywhere, strainer especially full of black 'carbon' particles, about 1/8" in size the largest.
Strainer off for a good clean, wiped as much as I could by hand (more difficult on a tdci due to the ladder frame) and did contemplate on an engine flush. Changed oil brand (went to Millers as that is what I use on my engines) and opted not to use any engine flush. Within about a month or so, low oil pressure light came on again. Sump off again, strainer clogged with more 'carbon' particles, but rest of the engine was looking much cleaner than previously... the Millers oil was cleaning off what I could not get to. On next service, I took the sump off again, engine was looking spanking clean. His driving habits did not change... just the brand of the oil had changed.
Note that I have no affiliation with Millers, but just reporting my experience. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

oil sludge is mainly caused by too long operating time of the oil or internal engine problems. One can/should determine the basic and acidic potential of the (changed) oil by oil analyses in order to match one's own driving profile with the oil used and at the same time confirm the functionality of the engine.

Indeed, this is highly interesting science but not yet understood in the last consequence. Therefore it always offers a lot of room for "opinions". But there are great forums where such things can be discussed in depth... Very Happy Thumbs Up
