0w40 is going to be thinner than 5w20 at startup when youre having your problems.... the first number is viscousity at start up, and the second is viscousity after its warmed up...at start up you would be running 0w instead of 5w, and at operating temp you would be running 40 instead of 20...
i wouldnt do that if it was my car...if you wanted a thicker oil, 10w30 would be your best bet... whether or not it will help quiet things down though, i do not know

thanks for the feedback how about running just w40? again my oil pump seems to be whining is this common or is it a problem? it doesnt leak oil consume or anything is just that my drivetrain is really loud and i was just relating the pump whine to be the cause of this. i mean the idiot gauge is normal but the car runs rough and loud

If the engine is running rough and making noises, there might be something else going on. Have you diagnosed any of this yet?
A thicker oil will flow at a slower rate, reducing lubrication, increasing engine temperatures, increase engine wear, reduce power and also fuel economy.
Are there any other symptoms? How long has this noise been occurring? Has the oil pressure in the engine been checked?
