After bad oil leak, engine ticks. Help!

[dayspring_theory]

Well, I was driving home from work and my oil light came on and went off. Came on longer and went off. Finally stayed on and then my valves were all clicking due to only like 1 quart of oil in the engine. Got oil and put 3 1/2 quarts of oil in the engine. Went to close my trunk and it was coated with oil. Not good. Drove it home and found I had a major oil leak. Dropped it at the shop next morning and found out the oil sending unit busted. Got it fixed and now I notice when the engine gets warm I have a valve tick. No loss in power however. Not sure if this can be answered but will this clear up? I was planning on Sea Foaming the car to see if I could get it cleaned up. Any help is greatly appreciated!
