You have found your problem. The play in the crankshaft is enough to play havoc with a couple of things. It will continue to kick out the seals. I would say you may have a bearing that is bad or since the bearings are split that one has popped out. Either way there is a bearing or two that is gone. You will continue to have seal and oil leaks.
On top of that, those two sensors are not able to correctly tell the computer their position because there is too much play in the shaft.
Not really that great of a bit of news for the Christmas time period. You seem pretty savy, and with a torque wrench and a little elbow work you could lift out the engine and rebuild it. I have purchased an entire kit on ebay for about $125. I put on a new oil pump, water pump, timing belt, clutch and had just under $500 dollars in the rebuild. Only pain in the butt was I did not have cherry picker to pull the engine but with some digging you can borrow one.
Good luck and ask more questions as needed, we like to help!
