Finally got my photos up regarding de-coke.
My car has done 74k, had one owner and FHSH , have changed and serviced it about 4 times and have done 16k so far.
Always used premium diesel when possible, and spend 75% of my time in traffic lights!
Mine seemed pretty bad compared with some people's:

Took about 3 hours to clean off all the soot- used 2 cans of oven cleaner and a special high pressure swirl nozzle on jetwash - really helped with the clean.
Used wire-wool to remove some of the fiddly parts and carb cleaner, then made sure no residue left, and bone dry.
Also sprayed inlet manifold in high temp black to keep temps down
and radiate more heat for denser air temp
well it looked nice.
Only annoying thing was 1/2 drive was too big , and 1/4 inch too weak to crack off some of the nuts (bust ratchet).
Ordered a 3/8 teng tools kit in end (needed an excuse !) and found it just the right size.
Also dropped a manifold bolt , and never found it again- really easy to have bolt fall off .
When ***embling I used new gasket for inlet (part number PFKL348435 ) £20 and 1 new bolt :angry:
Also put some duct tape in socket , and physically pushed bolt in before ***embly- it don't just fall off then if you touch something and certainly helped me in re-***embly.
Pushed a little bit of lint free rag in each of head manifold ports , and used a old 1/4 wide screwdriver , which I heated then bent 90 degree's to make a scraping crevice type tool.
Pulled a lot of residue out of head as you can hopefully see in photos - just took ages.
Did find torque setting for inlet manifold, but could only get to a few of them so just used experience I suppose, but with new gasket I did not really worry .
No pressure in fuel lines for me , and once put back together , just cranked it up and started no worries.
Left insulating cover off for a few days to see if high pressure lines leaked, but all fine.
Just order a gasket before you start,as I forgot and was out of action for a few days
The most time consuming part is undoubtedly the cleaning! just start first thing in the morning , and it should be back together by evening!
Hope this helps a little bit
