There is a slight knocking noise and coolant seems to drain quick.

first thing to do is check oil level, and get an oil pressure test done, i would like to see the oil pressure readings at cold idle, hot idle and hot at 1500RPM oil pressure test is fairly simple you do need a mechanical oil pressure gauge that will screw into the oil pressure sender port. A cooling system pressure test will help locate any external coolant leaks.
