Hahaha, sounds like you've been there before!
Took a step back. Made a cuppa. The left hand long M6 bolt that clamps the head to front cover looked like the offending item. I removed the bolt, and the water leak immediately got worse. I therefore added a little Loctite 542 just in case the bolt travels through to the water jacket and tightened it up to 20Nm. The leak, so far as I could see, then stopped. I checked the torque of all other bolts and ensured they were tightened to 20Nm.
I went through the bleed procedure for the injectors, and once it started to leak diesel and intermittently fire (this did take a good 30 seconds of cranking), tightened them up. I then started the engine and it fired to life. After a few minutes the idle smoothed out and the hydraulic lifters quietened down. It now idles absolutely beautifully and there is no water leak from the head that I can see.
I ran the engine for 25 minutes as per RAVE, and then shut it off to cool down overnight tonight.
The pickup on throttle most of the time was absolutely spot on. I didn't want to put it under boost, even sat on the drive not moving, before the head is torqued the last 90 degrees, but blipping the throttle briefly, it felt torquey.
I did notice a couple of times a few minutes after starting, the engine didn't respond to the throttle at all. This seemed to instantly resolve itself when I fitted the intake runner across the top of the engine to the air filter, but this may have been coincidence.
A few things to check tomorrow in addition to the final head torque is a small oil leak from the camshaft vacuum pump o ring (it is new) and diesel leaking from No.1 cylinder leak off (the pipe that goes back to the pump, all others look fine).
and I'm afraid wammers passed away a short time ago,but his legacy lives on.
