No, knocking in an engine is normally more serious than a gasket leak. Depending on how heavy the knock sound is it could be the Big Ends bearings need changing or it if its fainter than that it could be the timing is out. Either way it can cause real damage to the engine and should be repaired as quickly as possible.
Have seen exhaust manifold gasket leaks that are described as a 'knock' by inexperienced persons. Normally a knock is piston connecting rod bearings that have gone out.
