1991 Honda Accord Squeal Engine Noise

    I have a 1991 Honda Accord SE that recently started a high pitch squeal
    coming from the engine bay. When sitting at idle, nothing. When
    starting to drive, a squeal that starts for awhile and then dissapates
    to start all over again. I have searched and searched and read that it
    could be anything from ABS motor, timing belt, Distributor, and
    alternator bearning. It is coming from the passenger side of the bay
    and tried running next to car to isolate but cannot. Distributor
    housing, rotor, ignitor, and cap all replaces last year so don't think
    that is it?

    Can ANYBODY Help me?????

    Remove the distributor cap and look for Red Rust. Check google (groups)
    if you find red rust.

    If you're running next to the car I would assume the brake pad
    wear sensor. If it's from the engine bay maybe spray some WD-40
    on the distributor bearing.

    I could be mistaken, but I believe that they are sealed bearings. In order
    to lube it, one would need to remove it and pop the seal out, clean it up,
    put some grease in it, put the seal back, and then reinstall it back into
    the distributor housing. It's not a terribly complex job, but certainly
    more involved than just spraying some wd-40 into the distributor (which by
    the way probably isn't such a great idea since it's particularly flammable).

    well, it's not that easy either. the bearing is non-standard [and not
    cheap] and the housing sensors /should/ be recalibrated on reassembly.
    unless you really know what you're doing, replacement of the whole
    housing assembly is a much safer thing to do. and if you price your
    labor on trying to replace the bearing, there's probably not much in it
    on cost either.

    sounds like an accessory belt. bearings don't usually get quieter as
    revs go up.

    when you say "passenger side" is that left or right? depends on the
    country you're in!

    Does the noise start again when you press the brakes to slow down again?
    Then inspect the brakes.

    Also have all the accessory drive belts checked. Does the noise appear on
    the first startup in the morning?

    Thanks all for the responses - but I know it is not the breaks per se
    or the accessory belts. The "squeal" is like a fan hitting the shroud
    or the radiator and grinding on metal and goes for about 10 sec and
    stops and then goes again a few seconds later and stops. It never does
    it at a standstill or idle but always does it when driving (whether you
    are accelerating or not). Breaking has no impact on the change in
    noise other than when you get the forward momentum of the car stopped.
    Then no more awefull grinding noise.
    I read a post listed 2 years ago that indicated the ABS fuse was pulled
    and a noise exactly like the one I have stopped. So in that case -
    maybe the anti-lock breaking system has malfunctioned. I'm thinking
    more along the problem with timing belt or possibly a malfunctioned
    distributor. However, I have questions about distributor making such a
    noise- since all is new less than a year ago. And why wouldn't the
    distributor make the same noise at standstill if reving the motor up??
    Very baffled!!!

    Thanks Curly. I see just barely some red dust. Hardly noticeable.
    And if it is the distributor, wouldn't that grinding noise increase as
    I rev up the motor??

    Exactly what I'd say. I'd ripped the distributor apart on a 92 Civic only to
    clean, grease and seal it with clear RTV silicone. These bearings are sealed
    and not standard otherwise I'd swap the bearing. Overall, I'm expecting the
    car to last over 200k.

    From a flashlight I can clearly see the distributor bearing on a 92 Accord
    after removing the rotor. Get a nice, long nozzle and get a clean shot at
    the bearing (sealed or not) while agitating the shaft. The WD-40 molecule
    is penetrating enough to stop that squeak.

    Not as flammable as aerosol starter fluid.

  11. Just a thought - my daughter's '93 made an intermittent squalling noise when
    the coolant was low. None of the other symptoms, just a squall like a seized
    bearing. Weird.
