Either your oil needs to be changed but most importantly The clearance in the connecting rod bearing have more clearance then tolerances allow. This could be due in part of low oil pressure. The gauge might show safe pressure but a manual gauge would give an accurate pressure. Hope this helps.

That could be only two things one a bad pistion or a bad rod. I would take the engine apart and find one or both maybe broken or in bad repair fixing. I would not drive it far it will throw the pistion or rod right through the engine costing ya more money or a new car.
