Just an update four you, We did a exhaust pressure test and that was all fine the cat is fine, we replaced the post cat 02 sensor and still same problem (low power and hesitation)
I have inspected the turbo inlet fins and they are fine turbo spins freely.
Did a cylinder compression test that was fine
Did a full leak down test and that was fine, all three had a little loss that could be heard through the oil fill cap but it was on all three and very slight. No bubbling in the coolant during the test so I'm eliminating clacked head or head gasket for now.
So now I'm really stuck as still no fault codes and still the problem exists.
Was thinking next step would be to get a cheap boost gauge and actually check its making boost.
Then possibly try replacing the low pressure fuel pump as I've heard these can cause similar symptoms but not show a fault code.
If anyone wants to add suggestions or ideas feel free to comment and let me know as I'm really at a loss now!
The only other thing I'm not sure is normal is when the car is running its sounds very quite and normal but if i remove the oil fill cap there is a load tapping noise from the rocker cover does anyone else's ecoboost sound like this when they remove the oil cap?
Possibly a fecked tappet/follower/cam loab? would that cause the loss of power and hesitation? remember we are down about 50% on power.
