White smoke coming from exhaust smells like fuel

Fuel in the oil and white smoke and it is a SIDI
HPFP (high pressure fuel pump) passenger side at rear is driven of the cam and if it leaks internally it does everything you have mentioned.
Pull the passenger side rocker and you will have a really clean top end from all the fuel cleaning everything and if you keep driving you can say goodbye to your engine as you start fitting a new one.

No but you need to find the fault and fix it before it does anymore damage.
Get enough fuel in the oil and it can destroy a engine quicker than you can blink.
Passenger side rocker cover off and check and change your oil pronto.

Remove the radiator cap & run the car for 30 minutes. If it doesn't explode or keep producing bubbles, it's not a head gasket failure. Car will also misfire like hell at idle if coolant is being sucked into the combustion chamber (fuel, the water in coolant & air don't make for an efficient burn/explosion).
Fuel smell generally indicates a problem with the catalytic converter.

None of that explains fuel in the oil though which is problematic.

The problem with that on an Alloytec is there can be trapped air in the cooling system as many don’t maintain them too well, or service them correctly. The end result is seeing trapped air releasing and thinking it confirms a fault.

Do a compression test.

The most likely way the fuel is in the oil is as mentioned, via the high pressure fuel pump on the motor.

Attached is my compression test.
I did it dry and it was pretty chilly outside.
Numbers ranged from 150 - 130. Is this okay?

140 is as low as I would like so the 130 is a worry and no more than 10% between cylinders you are around 15% between highest and lowest.
Really should have done a wet test with a squirt of oil in each cylinder to see what they bounce up to as that would give you more of an idea if it is a bore & piston problem or a valve & head problem.
But it also can depend on how accurate your gauge is and a number of other factors but I wouldn't be pulling anything apert based just on that one test without doing a follow up wet test.
