how to eliminate the noise ?

[nakar]

HI...EVERYONE , I'M A NEWBIE IN THIS FORUM, i like to ask something about the noise in my engine, my TOyota Trecel 1991 . Every time i start the engine ,it make a rotating noise, and it goes away after a while and while i'm driving most of the time when i revv the engine it makes the same noise, at first i thought that was the water pump deffect , i did change it and that noise is still there..Anyone please share your info if you have a similar problems ? or what is the noise comes from .? or what should i do in order to get rid of that bugging noise ?
REALLY APPRECIATE and thank you in advance.

A rotating noise? Can you be more specific? Is it a clank, a rub, a knock? Try to give us a better description and also use a mechanics scope to locate the source of the noise.

Maybe a spun bearing? Maybe a bad piston ring? You need to get that scope and see where in the engine it is coming from. High, the piston, ring, or valves. Low, the crank or rod bearings.

my first assumption when you said rotating noise was that that was the sound of the engine running....sorry to disturb..
