Default Cold engine knock

Switched back to Havoline.There wasnt any change.There werent any foreign materials in the oil.It looked great no grit no grime, and no metal.One thing I did notice was during warm up the engine surged a couple of times and each time the knock went away for a split second.This happened once before I switched oils and twice in a row the next day after I switched.

Any ideas with the new symptoms?Im about ready to take the plunge and take it to a mechanic.Its out of my league.

Anybody know anything about this? Thanks
