Smoke coming from exhaust but still driving

Hello, i'm hearing multiple different symptoms here that could need addressed. Smoking - could be due to oil burning, or a fuel / air mixture issue in engine performance, or a misfire concern. You have to test engine performance and base engine operation to narrow this down. Ticking noise, could this be engine related? The noise should be heard by a trained ear that can give good advice. You are saying that everything was perfect prior to adding oil? This would concern me that maybe your vehicle did not need oil and could now be overfilled?
