High pitched whining...

Post by psburtis »

hey all,

when i'm running under 1500 rmp's, i notice a very high pitch whining coming from my engine. when i rev it to above 1500, whether i'm parked, in drive, or in neutral, it still whines. any ideas?

thanks

Could be a number of things, but probably the PS pump or another bad pulley. Remove the belt to see if the sound goes away.

dang, that sounds like a great plan... except i'm leaving st. joseph (a town about 10 minutes away) at about 9am for home (my school is just starting our easter break).... if you'd be thru before 9 that'd be great, if not, well, maybe next time...
