Clanking or knocking noises can be caused by bad rod bearings which are caused by oil deprivation. Check your oil quality and level.

the oil was changed about 3 months ago, i checked the oil level today on it and it's only slightly low. there was no knocking at all the night before. my mechanic is advising i get another engine. i'm just baffled why this happened.
