Often when the oil pressure needle starts to oscillate wildly, that is a "definite indicator" of a bad oil pump or a possible faulty oil sender.
What I am concerned about is a knocking noise from engine. That to me sounds like "insufficient" oil supply.
These "clowns" have had your explorer for almost 3 weeks? !
To eliminate the oil pressures possible bad sender all they need to do is check it with there equipment. If they are receiving acceptable oil pressure, it is the sender. They should replace it and you will be all set. If the oil pressure reading is insufficient it is the oil pump. They should just drop the oil pan and replace the pump (one of the two. Plain and simple).
I am wondering about another thing. With "only" 80,000 miles ! Why did they pull the engine out to change the timing chain/chains.
If it "was" the chain/chains, why did they need to pull the engine !
Almost 3 weeks with it. What are they doing rebuilding the engine. Even that would not take long at all.
Something is not right there ukmex !
That is just my opinion.
Just for giggles, let me know what happened.
I hope you get your explorer back soon.
