Done a couple of small things this weekend, I've managed to flip the coolant return on the back of the turbo 180 degrees so it now points down and also tried the same on the front one with little success.
Im going to make up an extension piece that will bring the banjo out from the centre of the turbo so it can exit horizontally which will make the centre of the turbo the highest point in the system besides the header tank, which i have no raised slightly to make sure its above the turbo.
A good bleed next weekend after i make this extension and hopefully its going to be solved.
Might look at the oil return today as well.
