    Chirping noise under load D2 V8

    I have a chirping noise under load, sounds like a manifold leak but I just installed headers and new exhaust. Noise was there before upgrade. MY props are 100% fine because when I removed them the noise was still there. I replaced all the pulley bearings and idler pulley, noise is there with serpentine belt removed. Could it be spark plugs? Revs fine when stationary.

    My shaft looks fine as well but both on car and on the test bed at metro Driveshafts it sqeaks/chirps away. I'm not risking the transfer for it. Did the research and unless the splines and cap holes are all ok and you do the work yourself a woods shaft works out cheaper than having it done by either of them.

    I have heard failing head gaskets squeak on older P76 motors, out the side under the exhaust manifold. Long nose pliers holding a strip of paper near the gasket line can help find the leakage spot. It also stops when you short out that plug.

    Water pump?
    Grab the fan top and bottom and try and feel for movement within the bearing.

    It seems like a intake or injector leak.
