The two are not related but I have seen bearing knocks so bad the engine jumped and twitched like it was missing, about ten seconds later it threw a con rod though the side of the block
And engine knock is normally caused but I worn crankshaft bearing or rod bearing.
A knock probably means a bearing has already gone.
bearing on crankshaft worn or damaged, caused by lack of oil. start engine if it will and pull plug wires off one at a time and you'll find out wich one. do not rev up engine too high. do not sell car to a friend. motor has to come out and extensive repair on lower end required. if you do not know what a rod bearing knock is then it is not a do it yourself fix. major repair.
