I should probably update about my issues actually.
Phil and I ran it up with a pressure tester the other day, and whilst the pressure never went above 1.3 bar it is losing a lot of water into the oil.
This is after a 15 min idle at running temp -
Luckily for me the South West is full of helpful/wonderful VAG owners and Russ (slowcoach) had a head for me in his garage. So we went and picked it up on Monday night and had a good old chin wag. I can't thank Russ enough, knowing that we can just throw a head on it and not have to worry about pressure testing and skimming is a huge weight off my shoulders.
The head has done very few miles since being totally reconditioned with all new parts
Can't wait to get it all sorted on Sunday and have him back
New water pump, cambelt and head
