Start with misfire on number three cylinder. I have changed the plugs and plug-leads and coil-pack. Combustion chamber stays black and spark plug, if take off cylinder head, but valves is white.

Did you take the head off already? Then you have to re-time cam etc. On misfires I always recommend that you take to a professional because it can be a basic engine problem, injector or any sensor messing up causing this. It is the cheapest option so you do not end up dumping money into good parts like you already have and doing unnecessary work. We do not list a 2012 on a 2013 head bolt torque is 16 ft lbs + 82 degrees. See picture.

So you cannot tell me definitively on number three all of them doing it. That it is an injector.

Unless you do a freeze frame and go through all the sensors and check fuel pressure with a gauge you wont know a thing other than it is misfiring.
