I did wonder myself with the pump timing, as you say its just a high pressure pump being common rail system I finally have the head stripped off now and what I found was on number 4 cylinder the liner had a crack about 30 mm long next to the water jacket, its was pitted and I could see where coolant had seeped through The gasket had a dark stain in one place and also on the head , all the others had a clean unbroken ring mark on the head , checked the head with a straight edge and there are no signs of warping but I am going to have skimmed to be on safe side while its off plus grind in the valves and fit new stem seals Removed the sump to gain access to no4 con rod to find these engines have balance shafts that are timed to the crank , just more to take off According to VM information the liners can only be removed when engine is out and disassembled with crank removed , I made a puller/plate that just fit between the bottom of the liner and the crank and a bridge that cleared the top lip of the liner , with a long M20 bolt through the bridge and screwed into the lower plate I tightened the bolt and the liner came out with not too much effort New liners are about £80 inc vat then a set of rings , just got to measure old liner with shims and make sure new one is set the same TBC
