General engine health can be determined by testing compression, oil pressure and blowby. The noise you describe can be caused by several things. Check the "temerature riser", a valve that allows exhaust gasses to cross over the intake manifold to pre-heat a cold engine. Also check the EGR valve. If it's leaking it can sometimes make a sound that might be interpreted as tapping. It could also be a collapsed lifter. That often occurs if the oil hasn't been kept clean. There are a few engine cleaning products that help occasionally, but don't count on it. You might also want to check your exhaust manifold and gasket. If the gasket is blown, or if the manifold is cracked, it can also make that loud tapping sound.

Serious engine damage will occur if you continue to drive a vehicle with a blown head gasket. You can see any or all of these symptoms. White smoke coming from the exhaust, A sweet smell at the exhaust, Loss of coolant, Coolant in the oil, air bubbles in the radiator, engine miss.

What is the difference between white smoke and steam coming out the tailpipe?

You will see steam come from the tailpipe in the winter which is caused by the hot exhaust coming from the engine making contact with the cold metal in the exhaust system. This is normal and no cause for alarm. However if the white smoke does not dissipate almost instantly and seems to continue you may have a blown head gasket. If the exhaust smells sweet you almost certainly have a problem and the gasket is blown. A blown gasket will destroy the engine in time. If you are not sure have it looked at by a professional.

How do you tell if a motor is blown?

Your answers will vary on this, however I do not consider a motor "blown" unless it has a hole in it caused by an explosion or internal malfunction such as a rod thrown through the engine block, or if it has over heated ( extreamly ) and warped the engine. if the engine is not fixable I say its blown. Some others will call it blown if just the headgaskets are blown or maybe if the engine jumped timing. These are fixable and even if an engine piston rod is broke but has not injured the block it also can be fixed. each Mechanic has their own opinion on what is called blown, some will call it blown just because they don't want to work on that model. Get a second opinion always !
