Stock KA24DE ? What kind of Valves did you use ? OEM Stock ? Aftermarket ?
Plain and Simple, it's unburnt fuel. Running way too rich, check if you got any oil leaks around. Might help if you lift the car up somewhere around a local shop. Check if Oil is entering an Area that is not allowed. Like for example, Spark Plug chambers. Plus when you replaced your valves, did you use a new valve cover, and head gasket, it can be a stressed valve cover gasket, or maybe a stressed head gasket.

Could be a faulty coolant temp sensor or a dirty connection. Cause your car to stay in open loop...
I'm sorry, I meant to say Valve Cover Gasket.
