Engine mechanical testing starts when you open the hood. So, The visible condition of the engine can tell you a lot about its performance. Consequently, Is the battery growing white fuzz on the terminals? Also, Are the drive belts cracked, glazed or worn? Furthermore, Are vacuum hoses loose, damaged or connected improperly? Do you see any wires that are broken or frayed? Finally, Are nuts, bolts and studs on manifolds missing or broken?

Before you even think about cranking the engine; look for signs of fuel leakage. Then, Remove the air cleaner and check the condition of the filter. Also, Examine the (PCV) valve and hoses for damage and wear. Then inspect the coil, distributor (if the engine has one); plug leads and terminals for carbon tracking and broken insulation.

Above all, Don’t forget to pull the dipstick and check the oil condition. Also, look for oil leaks at valve covers and other seals. Finally, Check the inside of the radiator for dirt; rust or other crud. Furthermore, Don’t overlook all the coolant hoses.
