Hi,
Did this happen right after the spark plug/coil replacement? Also, is it possible for you to record the engine running and upload it for me to hear? That may help me.
In the interim, double-check if the ticking could be coming from a loose spark plug or if one may have been cross threaded.
If the check engine light is staying on while the engine is running or flashing, let me know that as well.
Take a look at this link. It describes different engine sounds and possible causes. Let me know why you feel there is no oil circulation as well.

Let me know.
