I hope it isn't the situation where the oil pump drive pin fell out - and you are not pumping any oil through the engine!
There is a small pin in the gear behind the clutch that can fall out when you take the clutch apart, and if it is gone you are not driving the oil pump. The knocking could be the parts without oil self destructing.
Find the gear behind the clutch and the other gear just forward of that - see if you can turn those gears without the clutch turning.
