Get a clear diagnosis first, pull the motor last. It's a process of elimination. I would get a PST2 on there and dig deeper into the problem. If you are getting a bunch of random error codes in might be damaged DME wiring by rodents or maybe it got wet or overheated. Little car computers don't like water or excess heat.
Any oil/coolant intermix?
Make a list of possible causes and check them off starting with the easiest one first. Don't swap any more parts until you are sure you found a bad one.
