With that much fuel coming out, are you sure there isn't a stuck injector that has washed the cylinder walls clean of oil? The oil in the vehicle is likely contaminated as well.
If you suspect compression, did you try a wet compression test to see if there is a major increase in compression?
As far as the engine vs year. It matters. If you find one with a "B" engine code in the VIN, they are the same. If it has an "M" engine code, they are different. Both are a 1.4L turbo but they are different engines.
I attached three pics below. The first is the 2015 engine. Pic two is a 2016 B code and pic three is a 2016 M code. I attached them to provide the manufacturer's part numbers.
Let me know if you have done a wet compression test and I would remove the fuel pump fuse, so it stops pumping fuel, but that's your call. LOL
Take care and let me know what I can do to help.
