In a small bowl combine oil, salt, pepper, minced garlic, brown sugar, paprika, and onion powder. Stir the mixture well until combined.
Rub the mixture all over the pork.
Wrap the pork with the bacon, I placed the pork on bacon slices to cover the bottom, after that, topped with more bacon slices, this way the loin was wrapped all around with bacon.
Use kitchen twine to keep the bacon in place if needed.
Place pork loin into the slow cooker and cook on low for 4-5 hours. Baste a few times with the juices from the slow cooker.
At the end of cooking, place the pork on a baking sheet and broil for 2-3 minutes to make the bacon even crispier.
Let the meat rest for 15 minutes before slicing and serving.
