Could be tensioners cracking, or one maybe loose. Better do more research and get someones head under the hood!
It's most likely the hydraulic lifters. Over time the oil leaves deposits on lifter surfaces and it make them gummy. Sinthetic, mineral and additive oils will all do it. Short runs don't help either. Warm the oil, drain it, fill with flushing oil. Run it as per the flushing oil instructions, drain it, change the oil filter, refill with a quality oil that won't emulsify on short runs, and change it at regular intervals.The loud tapping sound can be caused by a complete heating of the engine. Worn tappets can also cause the tapping sound.
the first lifter facing on the letf makes a tapping sound sometimes
The house pest often associated with a tapping sound is the carpenter ant. These ants create noise by chewing through wood, which can result in a rhythmic tapping as they establish or expand their nests. The tapping sound is typically more noticeable at night when the surrounding environment is quieter. If you hear this sound, it's a good idea to inspect for signs of an infestation.

A tapping noise might come into the engine because of heat damage to the lifters of the motor. You might also hear a tapping sound if the engine has been damaged due to a blown head gasket.
It COULD be caused from the lifters bleeding down after the enginge has set for 2 months. Lifters make a tapping type of sound. Oil has a tendency to drain away from parts after sitting for a while.. It may even be your bearings were making noise. Bearing make a knocking..hard rapping type of sound. If the noise went away after a short time, it ain't no biggie. If it still makes noise you may want to have a tech inspect it.
