crankshaft problem

hello friends & nbsp; sound from the engine of the car & nbsp; I showed 5 masters down 2 above & nbsp; said the big possibility from the thrusters & nbsp; & nbsp; others said from the crankshaft & nbsp; meanwhile compression test was done & nbsp; robust output is all in good condition & nbsp; if I say crankshaft for crankshaft & nbsp; if the crankshaft has a problem, how do compression come out, why do the crank sound? & nbsp; make my beds sound ??? Let's say that the crank & nbsp; if the upper block needs to be opened, does the bottom crank open & nbsp; cranked and the beds cannot change? tsk ler & nbsp; for your help

do not have friends with an idea of knowledge ??? a bother

for the crankshaft, the engine must descend, the top has to be opened, but I know it is more likely that the sound comes from the thrusters

I can't understand it, I want to see the crankshaft and & nbsp; piston rods, etc., when I open the crankcase, I can't open it, why do I need to open all the top covers and all of them & nbsp; I'm not a master of course I am not claiming, but & nbsp;
