The leak appears from the near side of the car and drips off the underneath near where the crank shaft sensor is located. It is not a significant leak but is getting worse and is doing my head in!
I have replaced the HBV with a new genuine VX one, I have replaces the washers on the coolant bridge, again with VX, I have also replaced the o ring on the coolant transfer pipe - such a lovely job to do!
When Darth replaced the cambelt recently he noticed a bit of steam coming from the thermostat area.
So the plan now is to strip off the plenum, injector rail etc so that I can see the top of the oil cooler and other bits in the V, I am going to put pressure into the system (my local garage has offered to loan me a tool to do this) and hopefully I will be able see where the leak is.
The purpose of the post... If anyone has any advice I will happily listen.
