Just got my 92 SC300, had her on the interstate doing about 65mph and i wanted to see what she had in her. So i punched it and she did good for about 2 miles and i started hearing this EXTREMEly Loud whinning noise coming from the engine. Pulled over and checked the fluids and what not and the powersteering was low. I fulled that back up and drove out of the auto parts store and its still making this super loud noise. My steering is tight now so im thinking that i have tons of air in the system or the pump is shot. Any ideas let me know!

 

 

Well if you think you have air in the system why don't your try bleeding it then get back to us? :P

 

I just got done trying to bleed it but thats still not the problem. The funny thing is the noise isnt coming from the pump it self. It sounds like its coming from something on the passenger side underneath or behind the distrubitor cap.

 

Still sounds like your power steering pump to me, mang.

 

I tryed recording it hopefullly the link works! When i give it alot of gas it get louder then what it is in the video.

holy crap that sounds bad. but by the problems your saying it sounds like power steering pump...

peace out

 

hows that whinning? i was thinking electrical when you said whinning, but that sounds bad engine wise..

 

you power steering pump might be leaking

 

Um, that doesn't sound like a PS pump.

 

Thats the same thing i was saying! The only reason i say its the pump is because of the tight steering and when i get some one to turn the wheel the fluid barely moves. Im to the point where i want to put a new engine in her but i have no idea how much it would cost and who would do it the right way besides lexus. At the same time i want to find the answer to this so if anyone else has this problem they can know what to do(the entire purpose of the forum).

 

It sounds way worse than a pump... sorry I'm not much help here

 

i had the same problem on my 1gen gs and it was the tension pulley

 

Im going to look into that pully problem. Will let you all know what the deal is in the next few hours!

 

That would kind of make sense, it does sound a bit like the belt is lagging or something.
