Technical Timing marks urgent!
I am not convinced myself to be honest, but willing to give it a go.
I don't fancy ignoring the instructions and running it for 2 weeks when it says 15-30 minutes, but once you put the new oil in, you then put Forte oil treatment in and run that until the next oil change, so maybe that's a similar idea.
The risk I suppose is that some crud doesn't get flushed out with the old oil, but ends up where it shouldn't be, or washing away the carbon build up on an old engine makes the compression worse, but I can't leave it burning half a litre of oil in 200 miles so I have to try something before resorting to pulling the engine apart.

Its worth a 'Try, even if By following instruction's on the 'tin.,

My 16v cinq had one plug looking like your number 4, and the other 3 looked like your first 2. Chased the problem and ended up stripping the top end down and found 10 of my valves were leaking, the one that looked like your plug 4 had by far the worst valves. At first, on reading this thread that was my inital hunch.
only 2 of your plug conditions match, 3 is suspiciously clean compared to 1 and 2 which suggests it's running slightly hotter than 1 and 2, or 1 and 2 have the same issue and 3 is "normal". 4 as you know is showing the combustion process or fueling is gubbed on that one.
A bit of a shame you didn't get 3, because it would be an interesting comparison compared to 1 and 2 given the difference in plug colour.
.
But yes, those readings are high, 16.6 bar is 241 psi, to put that in comparison my cinq with leaking valves was around/just over 150psi, "normal" on a 16v engine is around 180psi, So for you to be getting over 240psi screams rings to me.
Well I tried the jungle juice treatment. Revving it hard afterwards didn't seem to produce quite as much blue smoke as before, and I couldn't see any under load or on over run on a fast-ish run, but then again it has been a sunny day and oil smoke is not so easy to see. I will keep an eye on the consumption but I don't expect this has cured it. The oil I flushed out didn't bring any great clods of carbon with it either, which I suppose is a good thing. I will keep you informed.
The lastest news is that daughter has driven the car all week (10 mile commute each way, with about 4 miles of mway and 6 in traffic) and the car used no noticeable amount of oil all week. On Friday night she drove it down to Somerset (210 miles) so I told her to check the oil when she got there (which she did this morning). The result was 1 litre of oil lost in that journey. There is a slight leak from somewhere which results in a small amount of oil running on to the oil filter mount (and it's not from the rocker cover), but nowhere near enough to explain that loss through leakage.
I am wondering, is the fact that it has lost 1 litre in 210 miles of motorway, but near enough none in 100 miles of slower driving a clue to where the problem lies?
Just trying to figure out what to do next.

check the breathers.. it may be forcing oil out at sustained higher revs..,

That's what I was wondering, but the only breather I know of it the 3 piece pipe that goes between the air box, rocker cover and block and that was all clear.
Are there any others to look for?
