My Series Rover has developed a new strange noise. It sounds like a power steering pump that is whining. Since I don't have power steering I know it can't be that. I have removed the fan belt to eliminate alternator and water pump bearings and the noise is still there. It seems to do it more after it warms up and I generally hear it at lower RMPs but the engine noise could just be drowning it out. If it is of any help my Rover is equipped with an oil cooler and I have just added a fan shroud since it didn't have one when I got it. It would seem to me that it can't be the fan shroud since the noise continues after the fan belt is removed even though it seemed to have started after I put it on. Oil pressure is good as is water temp. Any suggestions on what to check next would be greatly appreciated.
