  • Fwd engine squeeeeal, looking for tips..

    Gang-
    53 2R11 with a Commander 6. When warmed up, I have this annoying and (concerning) squeal emanating from the front of the engine.
    It only does it after being warmed up. And, only at (and above) a certain rpm..like a fast-idle and up.

    I thought it was the crank (no way! oil level good; good psi), maybe the water pump? It's low on the front of the engine, and definetley up front.
    A higher pitched: "eeeeeeeeeeeeeeeeeeeeee"...[xx(]beginning at a certain rpm and when @ idle -drops off *silent*. The slightest rev (increase in rpm) will introduce it once again. It reminds me of a small wire being drug across a dry chalk board.

    I assume you've eliminated belt squeal as the culprit?

      Yes, it is not the belt for sure.
      -It's not a slipping belt sound.

        Could it be the oil slinger inside the timing cover? Usually that is more of a chinging, bell-like, sound to my ear.

        Any chance the pulley bolts are working loose? That can generate all sorts of odd sounds, and can be load (and therefore rpm) induced.

          I was thinking oil slinger as well...it's a washer, if memory serve me correct. What the heck could it be contacting? I mean it's lived in the same 'neighborhood' for years!

            Greetings, danO,

            Just remove the belt entirely to eliminate the water pump and generator. Almost has to be one of them.

            You should hope it is not a wrist pin against a cylinder wall. Happened to me on a Champion way back when.

            thnx, jv.

              Packard-
              Will do...and it's too far forward to be a wrist pin...
              Will report result
              thanks

                Dan,

                Its a dished washer to my recollection, but I've not been insde a Commander 6 recently enough to remember what it could contact.

                  Take a metal rod, one end at the ear the other on water pump, etc. You should hear a smooth rotation sound on each component, if generator,etc is not the making the squeak. BE CAREFULL not to get the rod or yourself into the fan or other external rotating components.

                      maybe the alternator was going bad and it was making the noise? like a dieing pig or something hah.

                        Replaced said bad alternator. What a trick that was trying to explain to the Auto Zone boys!
                        Since the 'floods' began here in KS I have been way-limited in driving the ol boy around so plan to re-evaluate this weekend

                          OK I might be able to help you on this one! About 6 years ago, my Transtar started making a noise EXACTLY like this and while I couldn't pin it down precisely - I was SURE it was coming from the front of the engine. I was SURE it was.
                          Belt off - still squealed once warmed up.

                          Slinger was a suspect, just as some suggest here. Well, for it to be the source, this means the front hub has to have backed off and the crank end play will be causing other havoc worse than just noise. You're gonna laugh, but I actually ran it with the pulleys removed, the timing cover off and the front hub reinstalled. Messy as hell but it STILL squeaked.

                          What it FINALLY turned out to be was the damned manifold heat riser!!! Once warmed a bit to where it opened some, it's shaft had worn and polished enough that the pulsations of the exhaust gases made it squeak. Quiet at idle, but as RPMs went up it was there! Drove me NUTS trying to find it as for whatever reason (like a good ventriloquist) the sould seemed to come from someplace OTHER than where it really was.
                          Being in California, it wasn't really necessary so I just wired it open. Ahhhhhhhhhhhhhhhhhhhhh how nice not to have to listen to it's shrill serenade every time I went someplace!
