It sounds like the oil is not getting into the top of the engine so i would suggest an oil and filter change to start with, making sure you use the correct grade and type of oil-this is vital, don`t be tempted to use cheap stuff.
Why not try flushing the engine with a decent engine flush then replace oil and filter,that may help matters.
Check oil pressure with a master gauge to verify if low pressure .
